Look at the tire to diagnose car problems

(Baonghean.vn) -During operation, car tires will wear out quickly under the impact of the car's weight as well as the friction with the road surface.However, different forms of tire wear also indicate the errors that the car is experiencing, thereby allowing timely repair measures.

Below are signs of tire wear related to "diseases" within the vehicle's structure.

Center tire wear

This phenomenon is a sign that the tire is over-inflated, so that only the center of the tire is in contact with the road surface. If so, the vehicle's traction is also affected.

To find the correct tire pressure, look for information on the sticker on your car door or in your owner's manual; check the pressure when the tires are cool and before driving.

If you have the correct pressure but still see center wear, it may be a mismatch between the tire and rim. Some rear-wheel-drive cars can have some center wear on some tires even when properly inflated and cared for. But that’s only true for high-performance sports cars.

Sidewall wear

If the tire is worn on the edges but the middle is fine, it is a sign of under-inflation. A tire that is too soft will bend more when the vehicle is driven, and the heat build-up can cause the tire to explode.

Under-inflated tires will not be able to absorb shock and can damage the suspension system over time. To avoid under-inflated tires, simply check the tire pressure weekly if the car is driven a lot and monthly if the car is driven less. If tire pressure is consistently around the standard level but the tires are still worn on the sides, you need to take the car to a workshop to check the steering system.

Wear in clumps on the tire surface

In addition to reducing tire life, dents on the tire surface are also a sign that the vehicle's suspension or steering system has a problem, causing the vehicle to "bounce" on the road and become unstable.

Tire wear on one side

This is a sign of a problem with the steering angle, causing the tire to lean too far outward or inward. In this case, the wheel needs to be re-aligned.

Problems with the suspension, knuckles, and leaf springs can also cause one-sided tire wear. Other causes include carrying heavy loads, poor wheel alignment, and infrequent tire rotation.

Sawtooth wear

When you run your hand over the tire surface, if you feel sharp wear marks horizontally (only in one direction) or vertically, you should take it to a tire garage to realign the wheel alignment.

* Some operations to check and detect tire problems

- Observe the tire edge:Look for areas of corrosion, deep scratches, bulges or bubbles, small gaps or punctures. Check that the tire fits snugly and evenly around the rim.

- Look closely at the tire tread:Most tires have a wear indicator, or TWI. These are hard rubber pieces that are invisible on regular tires but appear in the treads that are worn about 0.16 cm from the tire’s surface. If this indicator appears in 2 or 3 different places on the tire’s tread, replace the tire.

- Check tire tread wear:To check for tread wear more accurately, place a thin ruler in the tire tread and measure the distance from the base to the surface of the tread. This distance should be greater than 0.16 cm (If the front tires are worn more than the rear tires and the tread pattern looks unusual, have your wheels re-aligned).

-Deflated tire:If your tire continues to deflate, take your car to a nearby service station to have it checked for punctures. Sometimes a rim that is not properly installed can cause a puncture. A service station can fix this problem using specialized equipment and tools.
