5 things to consider about tyres

5 things to consider about car tyres

There may be more than 5 things you can consider about your car tyres but today we will be mentioning the top five talked about topics and give you our advice along with some key references to consider.

Type of car

It doesn’t matter whether you own a car out right or drive lease cars on business or personal finance, you will at one point want to consider the tyres within the package before making that final call. If you are opting for a performance vehicle or a powerful engine then upgrading your tyres to something more suitable is definitely one of the options to consider.

TIP: Always look for the spare tyre and ensure you have one before getting a car. In most cases you would probably find a space saver that would temporarily do the job if you ever come to need it but if you have full size replacement wheel fitted with a road legal tyre then you’re in a for a treat.

Driving style

The tyres you want should suit the way you drive. For instance if you drive a performance car and like to take the speed to the limits wherever you are your tyres may wear out quicker than you expect. In which case you may want to choose high performance low profile tyres to better suit your driving style.

If you drive a luxury saloon and enjoy taking it easy in cruise mode than you may enjoy a smoother ride feeling less of the road in which case higher profile tyres with more rubber would probably satisfy you better.

Weather conditions

This one is important and could take you off the path if your tyres are not suited to the road conditions. You can be over the legal limit but still pose a danger to yourself and others so make sure your tyres are safe before you travel.

It is recommended that you either use all weather tyres or if you want the optimum performance from your driving then you could choose to change your tyres as per season requirements. High tread profiles for the autumn and winter months and Low profile slicks for the hot summers.

TIP: Some countries or areas could surprisingly change in weather unexpectedly. Using all weather tyres may be a safer bet.

Budget

Buying cheap budget tyres doesn’t always end up being cost effective in the long run. The quality of the rubber, manufacturing quality and design of the tyre play a big part on longevity and reliability. Choosing brands like Michelin could take you a longer distance and may even have a better resistance to minor punctures. But you must consider the unexpected and unfortunate tyre puncture and cost of replacement before forking out on premium tyres.

Legal requirement

The law states that the tread on a tyre must not be less than 1.6mm to be road legal. As unconventional it may sound, if you don’t have the professional tools or time to pop into a local garage you can quickly check your tyre tread using a 20p coin.

The Highway Code also mentions how important it is to maintain the correct air pressure in tyres for different vehicle loads.

Meeting the minimum tread requirement is not only a legal requirement but it must be met by the car finance companies before you return the vehicle at the end of your term otherwise they may be surcharged for the replacement of tyres to meet the standards.

Tire Failures and Tire Blowouts

Tire defects, such as tread separations that may cause blowouts, will severely limit the control a driver has over his or her vehicle.

When a radial tire suddenly loses its tread, the driver suffers a far higher risk of control over the vehicle. A tire blowout, or rapid pressure decrease in the remaining core, is often associated with a loss of tire tread, and drastically increases the chance of a dangerous rollover, particularly when it happens to rear tires driving at highway speeds. Loss of control can result in the rear of the vehicle swinging around to become perpendicular to the direction of travel, also known as yawing. If the yawing is not immediately reversed, then the sideways motion often leads to the tire bead separating from the rim, allowing the rim to dig into the pavement, which can propel the vehicle into a roll.



Rollovers may also happen if the vehicle comes into contact with grass, dirt or other drastic surface changes while in sideways motion.

Grass or dirt actually “trip” the vehicle, launching it into a rollover. “Tripping” occurs when there is a sufficient amount of sideways movement while the vehicle transitions into a grass or dirt median from normal pavement.
Tire manufacturers have known for a long time that a leading cause of tread and belt separations is inadequate design and placement of the belts and overlying tread. Poor adhesion of the tire components can also be at fault, and may be the result of the following factors:

  • Old and expired adhesives
  • Improper temperatures
  • Unclean manufacturing facilities
  • Contaminants introduced during manufacturing (rust, moisture, oxidation, grease, sawdust, gum wrappers, cigarette butts, etc.)

Of all the known problems that can cause belt separation, failure of the metal tire components to stick to the rubber is the most common. The method frequently used to bond these parts involves plating the metal with brass, then applying a rubber compound containing sulfur. If the mixture isn’t properly balanced, then incomplete adhesion occurs. This can also happen when brass plating oxidizes. Check for a shiny appearance, as it may indicate a deficiency in the tread bonding process, which could also be compounded by other defects.

Could These Tyre Care Tips Save Your Life?

Tyres are obviously one of the most important components of any vehicle, as they are the only point of contact between your car and the road.  Road safety is a serious issue, and it’s extremely important to take good care of your tyres as this might actually save your life one day.

Here are our top 10 tyre tips:

Ensure that your tyres are properly inflated in line with the manufacturer’s recommendations. Recommended air pressure values are usually stickered in the driver’s side door sill and also in the owner’s manual.
Under-inflated tyres will not only use more petrol, but they are at risk of overheating and becoming damaged, compromising your safety. Overinflated tyres reduce the contact patch, affecting your grip levels and handling, which can cause you to lose control of your vehicle.

When checking your tyre pressure, remember to do it when the tyres are cold and – if possible – invest in a good tyre gauge.

Regularly checking the tread depth of your tyres will ensure they have sufficient grip. Most tyres have tread wear indicators which show when a tyre is close to its minimum, so that you know when to replace them.

Monitoring the tread levels and adjusting your driving habits accordingly (for example, if it’s getting low you should take it easy until they are replaced).

If you have hit an object with one of your tyres, your wheel alignment may have been thrown out. This can have significant handling implications, which can be dangerous when driving. Furthermore, this can cause uneven tyre wear, which can affect your tread and cause premature wearing of your tyres.

Properly balanced wheels will allow your tyres to wear in an even fashion, saving you money on tyre replacement and ensuring that your car’s suspension does not wear prematurely.

Ensuring your tyres are rotated regularly (usually at each service but can be more frequently) will allow them to wear evenly and maintain good tread. A front wheel drive vehicle will wear its front tyres more quickly, and a rear wheel drive vehicle will wear its rear tyres more quickly. Therefore, regular rotation can help prolong the life and condition of your tyres, resulting in greater safety on the road. You wouldn’t want to let the tyres that drive power to be bald, as this can cause loss of control.

Whenever you wash your car, use soap and water to clean the tyres as well. Many people neglect the tyres as they are the things that are always on the road, however over time the tyres can pick up debris and even chemicals which can cause damage to the tyre compound.

If your tyre needs repair (for example, if you’ve noticed a slow leak or you’ve sustained a puncture) it’s important to let a professional assess the damage and determine the best course of action. Repairs should always be done by a licensed professional, as sometimes a tyre which appears to be sound is actually structurally compromised.

When it comes time to replace your tyres, ensure that the new tyres are in line with the manufacturer’s specifications. This includes size, maximum speed rating, and maximum load rating. Fitting tyres that do not meet the same specification can compromise the safety of your vehicle.

Despite popular belief, tyres actually have an expiry date. Whilst it’s hard to predict the life of a tyre, it is recommended that tyres over five years old are inspected at least annually by a professional. If a tyre is over 10 years old (from its manufacture date), it should be replaced even if it appears to be in good condition or repairable.

Most of us don’t store tyres, but if you have the need to the conditions in which you store tyres can affect their performance and longevity. Tyres should never be stacked for extended periods unless they are assembled and fully inflated.

It is also vital that tyres are kept away from flames and excessive heat. The area in which they are stored should be dry, well ventilated, and away from direct sunlight and any chemicals.

Tyres and their condition can often be the difference between life and death on the road, so it’s absolutely essential that you monitor and maintain your tyres on a regular basis. If in doubt about the condition of your tyres, always ask a tyre professional.

Hankook Survey: Car care still baffles some vehicle owners

WAYNE, N.J. (April 1, 2016) — With April marking the start of National Car Care Month, Hankook Tire America Corp. recently conducted a survey that revealed gaps in car maintenance.

The company asked American driversabout their plans and ability to spruce up their vehicles after winter’s harsh weather — including getting their cars in peak condition, from the interior to exterior and under the hood.



According to the Hankook Tire Gauge Index quarterly survey, many Americans focus on vehicle clean up, with a full two-thirds (67 percent) indicating they clean the inside and outside of their cars — ahead of both cleaning house (59 percent) and closets (59 percent). The company cited the Car Care Council that washing and cleaning a vehicle helps protect a motorist’s investment while preventing the buildup of damaging chemicals and dirt that can harm a car’s finish.

(Don’t laugh, but Hankook reminded drivers to make sure to close their windows if they plan on getting their vehicles washed — noting one in 10 Americans admitted to leaving their car windows open during the wash.)

Wayne-based Hankook’s survey stressed the importance of automotive maintenance, finding that 66 percent of respondents said they encounter potholes on their daily driving commute.

“If your vehicle is not properly maintained, a pothole can cause significant damage to one’s tires, suspension, steering system and even engine,” the tire marketer said.

Considering that 46 percent of Americans estimate they expect to hit at least 11 potholes this spring, Hankook offered a checklist for drivers to follow as National Car Care Month kicks off:

  • Check your tires — Provided they are properly maintained, tires can help prevent potholes from damaging a car. The company’s latest index revealed that 51 percent of Americans do not regularly check their tire pressure and 33 percent do not know how to do that. For best performance, Hankook recommended inflating a vehicle’s tires to the vehicle manufacturer’s recommended pressure — the information can be found in the vehicle’s owner’s manual.
  • Learn to change a tire — More than one-third (40 percent) of all drivers on the road do not know how to change a flat, the company index found. Among female drivers, that number increases to 60 percent. “A flat tire is one of the most frequent car mishaps, yet 17 percent of drivers ages 18-34 do not have a spare in their car or they are not sure where it is located,” Hankook said. “Take the time to learn the process so you are ready the next time a pothole sneaks up on you.”
  • Choose the right tire — The company also recommended that, with the change in seasons, motorists switch to more season-appropriate tires for their vehicles.

“Our quarterly Hankook Gauge Index helps us understand what is top of mind for American drivers around the country,” said Henry Kopacz, public relations and social media manager for Hankook. “As we head into National Car Care Month, our latest survey highlights the importance of vehicle care and tire maintenance to ensure safe driving.

“There are simple actions that drivers can take to improve the safety of their vehicle, and we want to make sure drivers are equipped with the proper tools and knowledge to do so.”

Hankook said it conducts its quarterly surveys to uncover American drivers’ attitudes and opinions about all things related to driving. The spring installment of the survey was conducted March 21-22, polling 1,020 randomly selected Americans on spring driving.

Pot hole damages to Tyres

POT HOLES – HOW THEY DAMAGE TYRES

Pot holes, unfortunately they are a common problem with a majority of the roads we commute on each and every day, a problem that’s made worse by bad spells of weather and a problem that’s not always fixed as often or as quickly as we would like due to local councils being affected by spending cuts from the Government and simply not having enough cash to fix road damage as and when it happens.

RISE IN DEFECTS

We have seen a steep rise over the last couple of years in the amount of vehicles that have been presented to us with defects or damage that has been either directly or indirectly caused by pot holes. Sometimes this damage can be very minor, maybe only a superficial scuff on a tyre side wall, but more often than not the damage can prove to be much more serious and even dangerous for the driver and his/hers occupants or other road users. And that’s not to mention the costly repair bill that usually comes with it all!

SIDE WALL DAMAGE

wall-damage-300x195The most common problem after hitting a pot hole is usually sidewall damage, as the tyre goes in and then comes out of the damaged road surface, the sidewall of the tyre can pinch itself together, this in turn causes a separation of the internal structure of the tyre and will usually present itself as a bulge or egg shape in the sidewall. Usually, this will result in some vibration felt through the steering wheel or through the chassis of the vehicle when driving, but not always so it is very important to have a visual examination of the tyre carried out after any sort of impact or after driving through a pot hole.

IF YOU HIT A POT HOLE, EXAMINE YOUR TYRES

If left unattended, a bulge of this type could result in a sudden deflation of the tyre, usually when the vehicle is travelling at speed and the tyre is heated through use. This can obviously have disastrous consequences for those involved.

POTENTIAL WHEEL CRACKS CAN EASILY BE MISSED ON VISUAL EXAMINATION

Another common problem we see after impact with pot holes is that of wheel damage. With many vehicles on the road having low profile sidewalls or run flat tyres fitted where the sidewall is very heavily reinforced, the shock of the impact travels through the tyre and can cause a crack in the wheel itself. This may not always be visible after a visual examination of the tyre as sometimes the tyre can come away unscathed, but this crack will slowly release the pressure from tyre and then we get back to the problem of the tyre suffering a sudden deflation or even possible total wheel failure, again with potentially disastrous consequences.

The only way to be sure that the wheel has not suffered this type of damage is to have the wheel and tyre assembly removed by a specialist to be properly examined, with the options if damage is found to either replace the wheel, (most alloy wheels can cost from £200 upwards depending on size and manufacturer) or in some cases the wheel can be repaired by a specialist wheel repairer which is much cheaper but not always possible depending on the severity of the damage.

SUSPENSION DAMAGE

The next items to suffer damage after pot hole collision is usually the vehicles suspension. All too often we see bent or damaged track rod ends, (which are the ball joints and metal bars that connect the cars steering to the wheels), broken coils springs (springs sit at each corner of the vehicle and carry the vehicles weight) and broken or bent suspension wish bones. Again, all of these problems often come with a costly repair bill!

WHEEL ALIGNMENT OUT

Even if after collision with a pothole you have managed to avoid all of the above scenarios, there is still the danger of the vehicles wheel alignment been knocked out. This isn’t something that can always be spotted just by looking at the vehicle, and it is not something that you would always notice when driving the vehicle (although common symptoms of the alignment being incorrect include the vehicle pulling to one side or the steering wheel not being straight when the vehicle is travelling in a straight line).

Misaligned tyres can wear out much quicker than they should, and can also have a detrimental effect on road handling and fuel economy so it’s always wise to have a specialist check the alignment after any form of impact, even if the vehicle feels ok to drive.

TYRE INSPECTION TIPS FOR AFTER A POT HOLE IMPACT

After any form of tyre impact it is always best to firstly carry out a visual check on the tyre, (remember that any damage wont necessarily just be on the outside of the tyre – the inner sidewall could also be damaged), be very aware of how the vehicle drives after the impact, listen out for any noises that were not present before and see if the vehicle handles differently. Also, keep a close eye on the tyre pressure, any drop in pressure should be checked out as soon as possible.

If after checking all of these items something is found to be not quite right, it is always best to let a professional check the vehicle over.

LOOKING AFTER YOUR TYRES


BY LOOKING AFTER YOUR TYRES, THEY IN TURN LOOK AFTER YOU

Tyres are often perceived as a consumable item, those black and round things that we have to replace every year or so, but tyres are in fact a feat of exceptional modern engineering, and they also play a vital part in us living the lives we do today.


SAFETY AND PERFORMANCE

Good tyre maintenance is absolutely critical in making sure that tyres perform to their best and get whatever vehicle they are fitted to their end destination or to carry out their role safely. The following tyre care tips are aimed mostly at car, van and 4×4 drivers but are also relevant to farmers and truck operators etc.


TYRE CARE TIPS

1. CHECK PRESSURES

The most basic but probably the most important tyre maintenance job is simply to check the tyre pressures, this is a job that ideally should be done once every 2 weeks, using an accurate gauge and always setting to the pressure recommended by the vehicle manufacturer. At any point, a car tyre only has a contact patch with the road surface that is roughly the same size as the palm of an adult hand, if the tyre pressure is incorrect, this contact patch reduces, ultimately resulting in a loss of grip.

In some cases with tyres that are dangerously underinflated, the tyre can build up a lot of heat which can accelerate the wear of the tyre and also in extreme case cause a sudden and total deflation of the tyre.

Tyre valves and dust caps play an important role in keeping air in the tyres, missing caps should be replaced straight away, and any damaged or perished valves replaced.

2. VISUAL TYRE CHECK

It is also important just to simply have a visual check of the tyre, any cuts or lumps/bulges in the sidewall should be inspected by a professional immediately, its all to easy to drive through a pot hole or scrape a kerb whilst parking and cause damage to a tyre.

 
3.VEHICLE MAINTENANCE

Keeping your vehicle in good mechanical shape can also help keep tyres in top condition, a car with slightly worn bushes, bearings or suspension for example can quite quickly cause rapid tyre wear and have a negative effect on the vehicles handling.

Regular alignment checks are also important, an incorrectly aligned vehicle will have an adverse effect on road handling and even fuel economy.

Tyre History

Tyre History

GOOD TIRES ARE VITAL for safety and performance. Unless the tires "grip" securely on every road surface - when it is wet, when it is dry, on rough roads and on smooth - the car cannot stop, corner, or even accelerate effectively. Tires must also give a comfortable ride, run easily, and wear well.

They have improved dramatically over the years, and modern "pneumatic" (air-filled) tires usually do this well, as long as they are in good condition. Careful design of the strengthening cords and webbing keeps the tire the right shape, no matter how it is squashed or pulled. The tread (the pattern of grooves) pushes water out of the way and keeps the tire in contact with the road.
Riding on Air
Old but not obsolete
ANOTHER FLAT!
A flat tire once meant a roadside repair.
BRUTE FORCE
There was no spare wheel, so the tire had to be levered forcefully off the wheel rim, and the inner tube repaired.
TIRE AID
Once cars carried a spare wheel, the wheel could be swapped and the flat repaired later
by a professional.
RE-TIRING
When early tires went flat, motorists often repaired them by "vulcanizing" with a sulfur mixture.
SOLID RUBBER c 1915
The first tires were solid rubber. They gave a hard ride, but never punctured and were used on trucks long after cars went pneumatic.
CUSHION TIRE c 1903
Long used on bicycles, pneumatic tires were first fitted to a car in 1895. They gave a much softer ride and soon replaced solid tires.
EARLY TREAD c 1906
Smooth early tires skidded wildly on damp roads. So drivers tried leather wheel covers and different tread patterns.
DUNLOP c 1909
Early pneumatic tires had an inner tube and were narrow. They were also pumped up to high pressure to help keep them on the rim.
Tyre Tread History
Rubber knobs to stop the wheel sliding and spinning on mud roads
Bumps to improve traction a little
Grooves angled in direction of rotation to aid traction on hills
BALLOON Tire c1930
By 1930 cars were using wider "balloon" tyres that ran at much lower pressure than earlier tires and gave a softer, smoother ride.
TUBELESS TIRE c 1947
In the postwar years, strong, broad, airtight wheel rims made an inner tube unnecessary. Now low-pressure, "tubeless" tires are almost universal.
RADIAL-PLY c 1972
In earlier tires, strengthening cords ran diagonally across the tire ("cross-ply"). Now most cars use "radial-ply" tires with cords running radially out from the wheel's center.
RACING SLICK
In dry weather, modern racing cars use huge, smooth tires called "slicks" to put as much
rubber as possible in touch with the track for good grip.
Long channels let water flow quickly out from under the middle of the tyre
Side channels allow water near the edges to flow quickly
Little incisions in the tire mop up water like a sponge
Water can accumulate in small ponds before it drains away
Tires have become wider and more squat " low profile" to increase the area of tire in contact with the road for good grip
Slicks get extra grip as the rubber compound gets hot and sticky during the race

Tyre Change

CHANGING A TYRE AND RIM EVOLUTION

A CAR WHEEL has a demanding role to play. It needs a good airtight rim to hold the tire in place. It must be strong, too, to bear the car's weight. And it has to be tough to stand up to the forces of braking, acceleration, and road bumps. Above all, though, a car wheel has to be as light as possible, for easy starting and stopping, and to keep the car's "unsprung weight" (p. 55) to a minimum.

To meet these demands, wheels have evolved steadily since the pioneering days, when wheels were big simply to give the car sufficient clearance over rutted roads. The first car wheels were adapted either from horse carts and were very heavy, or they came from bicycles and were weak. The car wheels of today are made from pressed steel or light alloys and are small, light, and strong.
Changing wheels
HURRY, THERE, JAMES!
Carrying a spare wheel in case of a flat was still such a new idea in 1912 that it was a major selling point for wheel and tire manufacturers like Dunlop.
RIGHT WHEEL
Horse-cart origins are unmistakable in this World War I truck wheel. The spokes are cast iron, but the rim is wooden. The wheel is immensely heavy, but strong enough to carry heavy guns. Wheels like this, and the bolt-on wheel to the right, were called "artillery" wheels.
Bolt-On, Bolt-Off
Flat tires were common in the early days, so the launch of the Sankey wheel in 1910 was a godsend for drivers. It could be unbolted and replaced with a spare in minutes. made of pressed steel, it was strong and light compared with wooden wheels.
WIRED UP
For many years, cars used either Sankey-type steel wheels or wire wheels descended from the bicycle. Early wire wheels were very light and the spokes absorbed some road shocks. But the simple radial pattern of spokes meant they were not very strong. On larger wheels the spokes would bend and "whip" at speed.
CHANGING WHEEL

Detachable wooden  rim pieces, or "felloes"

Cast-iron hub

Iron binding 

Hollow steel pressing
Simple radial spokes prone to "whip"
Five-bolt hub mounting
With spokes crisscrossed for strength, as on this 1913 Argyll (left), "whip" was no longer a problem. In the 1920s and 1930s, strong, light, wire wheels became the Wire wheel norm. Even apparently solid wheels like the 1937 Lagonda's (right) are actually wire covered by an "ace disc." A splined hub made changing a wire wheel easy; the wheel could be slid on and off the hub and held in place with a single "knock-off" nut.
STRONG WIRE
Crisscrossed spokes radiating from the hub take braking and accelerating forces
"Knock-off wheel lock
SPINNING A DISK
Wire wheels are costly to make and, since World War II, most mass-produced cars have had pressed-steel disc wheels. These are light, strong, and, above all, cheap to make. The wheel pictured is from a 1949 Morris; modern wheels are very similar.
WIRED FOR STYLE
Long after wire wheels were dropped for cheaper cars, they were used on sports cars for their lightness, strength, and good looks. This is from an early 1960s Jaguar E-type.
ALLOY THERE
In the 1950s, some racing cars had expensive disc wheels made from special alloys. This fits the same Jaguar as the wire wheel on the left, yet is even stronger and lighter.
CASTAWAY
Tough, ultralight wheels cast from aluminum and magnesium alloys are now widely used, especially for sportier cars, with a broad rim for low-profile performance tires.
