Diagonal Wear On Tires

Right here on Buy and slay, you are privy to a litany of relevant information on tire wear chart, tire wear indicator, tire wear patterns guide, and so much more. Take out time to visit our catalog for more information on similar topics.

Diagonal wear is caused by one tire running over a curb or pothole, which causes the inside edge of the tire to be worn away. This causes a vibration in your vehicle, especially at higher speeds and when turning. Diagonal wear is most commonly found on the outer edges of your tires.

Diagonal wear can also be caused by improper installation of your new tires. If they are installed with the angle of the side wall facing inward, it may cause diagonal wear to occur.

Diagonal wear can also be caused by a poor alignment or improper balance after replacing your tires.

Why You Should Be Wary Of Diagonal Tyre Tread Wear Patttern

The most complex tyre problems are uneven wear patterns. However, reading wear pattern is not an impossible task. We need to understand that uneven wear patterns are symptoms rather than being the problems. More often, it is the result of worn, loose or broken chassis parts, misaligned wheels or extreme service conditions.

One of the unusual wear patterns is the diagonal tread wear on the rear tyres of a front-wheel driven car. It is caused when the wheels of the car do not align correctly and do not follow the vehicle’s geometric center line. Now, you know that if the rear tyres of your front-wheel drive cars are showing signs of diagonal wear, then it is due to misalignment.

To narrow it down further, it is due to your vehicle’s incorrect axle toe settings. Because of this, the tyres will be pointed further towards (toe-in) or apart (toe-out) from each other compared the manufacturer recommended settings. The tyres will be positioned in a way that it simulates the condition of being on a gentle but a never-ending curve.

Generally, while cornering, pneumatic tyres grip the surface running at slip angles. Therefore, the misalignment of the front wheels may cause the rear tyres to grip and slip contact repeatedly while the front wheels are pulling the car in a straight line. This repeated grip and slip is what result in diagonal tread wear pattern.

Getting the alignment checked periodically goes a long way in ensuring better handling, good ride and less tyre wear. To catch the uneven tyre wear early, it is recommended to run your hands along the tyre tread to feel the uneven pattern. This method helps to detect the problem earlier than it can be noticed visually.

Tire wear patterns can tell you a lot about the health of your vehicle — from poor wheel alignment and tire pressure to worn shocks and struts. When neglected for too long, certain tire wear problems can lead to hydroplaning, blowouts, less efficient braking, spinouts, and so much more. 

Learn about common tire wear problems and what they mean for your ride.


If your tires’ inner or outer edges are wearing quicker than the rest of the tread, you may have a wheel alignment issue. This wear pattern often indicates a maladjusted toe (the inward or outward angle of your tires when viewed from above) or camber (the inward or outward angle of your tires when viewed from the front). 

Alignment problems can affect your vehicle’s natural ability to drive straight and can cause car pull — to the left or right — when you let go of the steering wheel. If you notice any of these issues, visit Tires Plus for alignment services right away. 


If you observe excessive wear down the center of your tires, there’s a good chance they’re overinflated. When tires are overinflated, the center of the tire gets more road time than the rest of the tread, leading to increased center wear.

Driving on overinflated tires can lead to loss of traction, premature tire wear, and make for a rougher, bumpier ride. If you notice excessive center wear, check your tire pressure to ensure the PSI falls within the recommended range. 


Excessive edge wear on both sides of a tire often indicates underinflation. Underinflated tires may start to lose their proper shape, leading to uneven weight distribution across the contact patch. With more weight over both tread edges, they may start to wear down significantly faster than other areas on the tire. 

Driving with uneven tire pressure can reduce fuel efficiency and increase your risk for a major tire blowout. If you encounter excess wear along the edges of your tires, check your tire pressure immediately and add air as needed. 


Diagonal scalloping wear of the tire tread or “cupping wear” often indicates compromised suspension components — typically the shocks or struts. Your suspension system keeps your tires from bouncing up and down as you drive by maintaining their constant contact with the road. And when this system becomes compromised, your tires may move more erratically, creating a scalloping pattern in the tread. 

If you notice this cupping pattern — or if your vehicle seems less stable, “bounces” as you drive, or is noisier than usual — consider having your suspension system inspected by a knowledgeable technician at Tires Plus. 


Patchy tire wear can indicate tire imbalance. This wear pattern often happens when a driver goes too long between routine tire rotations and balancing. Fortunately, if caught early, resolving this issue can be relatively simple. You’ll minimize the patch wear, extend the lifespan of your tire, and avoid risks like heat buildup, reduced traction, and susceptibility to punctures.


Cars can’t talk, but our tires’ tread often communicates when something has gone awry. So, what do the patterns in your tires say about your vehicle’s future? There’s no need to purchase a crystal ball. Bring your vehicle to your local Tires Plus, and we’ll diagnose and repair the issue for you.
