How to fix uneven tyre wear?

what can cause excessive or uneven tyre wear

Since you’ve known what can cause excessive or uneven tyre wear, you need to know how to resolve this type of wear. Drivers should check their owner’s manual to adjust their tyre pressure up or down as recommended by their car manufacturers. Once done, as time passes by, you will notice it helps tyres wear and prevent weak points.

Tyre wear patterns and causes

When you look closely, you will know they look basically the same. But vehicle tyres all wear in a different way from one another, even on the same vehicle. Below are the most common tyre wear patterns and causes.

Scalloped Wear

This is a bit different from center and outer wear, it happens in patches and looks like a cup. It normally begins from a faulty uneven tyre wear suspension system that doesn’t regulate your vehicle’s vertical momentum properly. The only answer for scalloped tires is to keep up with your suspension system when you observe your car is getting bumpier.


Even though an over-inflated tyre can cause center wear, an under-inflated tyre will lead to outer wear on both tyre edges. This is a common practice to air down the vehicle’s tyres to get more traction. So what can cause excessive or uneven tyre wear is that driving with lower air pressure will increase the edges’ contact with the ground.

This is because the outside carries more load than a well inflated tyre. Note that to minimize the risk of having outerwear, make sure you keep up with tyre pressure inspection especially when temperatures drop.

Feathered Wear

This one is a tad less intuitive. Whenever you have poorly aligned wheels, it will cause one corner of the tread to wear out roughly, and the other side to remain smooth and seemingly untouched.

Center Wear

When you find wear in the middle of your tyres, it indicates an over-inflated tyre. Whenever tyre pressures are beyond manufacturer recommended size, the tyre will bulge in the middle. When this happens, it will expose the center of the tyre to the pavement, which leaves the outsides relatively unworn.

So for you to prevent center wear and quicker-than-normal tyre change, ensure you retain your tyre’s pressure within the manufacturer recommendations, and use a pressure gauge whenever you want to add air.

What can cause excessive or uneven tyre wear?

An uneven tyre wear inside edge and uneven tyre wear outside edge can be caused by the condition of your car. This is most likely to be caused by the condition of your car in the following 4 areas:

Worn suspension components

Whenever a wheel stays too much to either side when running normally, it will put maximum load on one side of the tyre, and this can result in excessive wear. Sometimes this may happen because of worn ball joints, weakened springs, or problems with other components of the suspension system.

Air pressure

For a tyre to have the right amount of air is very important. When a tyre is properly inflated, then it will help in improving the driving quality and handling ability of the car. However, it is possible for tyre to get damaged when it is over or under-inflated.

It is possible for lots of air pressure to distort the tread and minimize its contact with the surface, which increases the wear in the center. When there’s under-inflation, problems will occur such as improper traction, increasing rolling resistance, and hard cornering besides the tyre wear.

Steering and wheel alignment

Whenever your steering becomes off because of misaligned wheels, then uneven pressure will be applied to the tyres on your car. When this happens, it can lead to uneven and excessive wear in different areas of the tyres.

Driving style

Your driving style is what can cause excessive or uneven tyre wear. Whenever you hit a kerb while you’re driving, things can be knocked out of alignment, and this will cause uneven wear. Note that sharp turns and fast-cornering can also result in excessive tyre wear. When you drive your car over a pothole, it can affect your alignment and make your tyre wear out.
