Tyre wear patterns

Abnormal Tyre Wear Feathered directional wear pattern. What is a tyre tread pattern? The tread will feel smooth when rubbing your hand across it one way, but rough when. Cupped wear pattern.

One of your tyres could be out of balance. Shoulders more worn than the centre.

If you examine your tire and discover that the inner or outer edge of the tire is wearing down faster than the rest of the tread, your vehicle’s wheel alignment is likely out of specification. This wear pattern indicates that your wheels are leaning too much to one side, which can typically be blamed on misalignment. Over-inflation Wear. Too much pressure can cause the contact patch to shrink and the center of the tire to carry all of the load.

Under-inflation Wear. One-sided wear – probably caused by incorrect toe or problems with the car suspension system. Spot wear – probably caused by sudden braking, incorrect balancing or alignment.

Feathering is also a frequent tread wear pattern.

Sidewall wear can weaken the core of the tire. Air pressure can exert greater force in this section since it is “thinner” than the rest of the tire.

In severe cases, the tire can buckle and lead to tire failure. Many of these tire tread wear patterns are due to bad driving habits, poor tire inflation practices, and improper balancing of the tires. Symmetrical tyre tread patterns deliver smooth driving, high directional stability, and low rolling resistance.

Directional tyre tread patterns provide high protection against aquaplaning, excellent handling on snow and mu and very good road-holding at high speeds. Whether tire wear patterns suggest something as simple as an overinflated or underinflated tire, or point to a more serious problem with the car’s suspension or alignment, by understanding what the tire wear patterns and molded-in markings mean, you’ll be better able to determine the overall health of your car.

Balance Issues: Improper balance will cause the tire to spin with a wobble due to unbalanced centrifugal forces. Bent Wheels: A bent wheel, in addition to. Driving over road debris or rough rocky road is what causes tire cupping as the wheels move and bounce irregularly, resulting in those scalloped patterns.

There is a likelihood of loose, worn and misaligned suspension parts with tire cupping. There is excessive contact with the outer edges of the tire, and the road surface as the vehicle travels down the road. The Fix:If the cupping isn’t very ba you can even out the wear after you rotate the tires. The effect of this causes a gradual and progressive irregular wear pattern.

A similar wear pattern can result from mismatched twinning of tyres. Solution: Identify and correct mechanical fault or defect on vehicle.

An accurate tread depth gauge can detect developing wear patterns earlier than simply looking at the tread. This often allows the cause to be identified and corrected before excessive or irregular tread wear ruins the tire.

If one or more of your tires are worn down the center — but not on the sides — the culprit is most. If you have consistently under-inflated tires, you’ll often find that your tread is worn on the sides, but.

The first thing you should check is the tire wear indicator (TWI), which is a triangle imprinted on the side of the tire. It points to a line of rubber that is built into the tire that runs across the tread. Tread wear indicator. If you notice this line is level with the top of the tread grooves, you will need to replace the tire.

Heel and toe wear is a pattern caused by normal usage and suspension settings.
