In terms of wear patterns of the tire«breakdown» refers to a series of regular expenses that appear on the outer edge of a car’s tread. tire. Also called «irregular wear», these expenses, from the outside, look like an ice cream container that someone has spooned the rubber into several times.

Why does a car tire come off?

incorrect pressure

Rotating with the tire below the indicated pressure increases the contact area with the tread, generating faster wear on the tire’s shoulders (extremities), makes the vehicle’s steering heavier and can generate an eventual breakdown of the tread (part that touches the soil) due to the excess heat generated.

How to know if the tire is defective?

When one side of the tire is almost bald and the other side is still rubbery, it can be caused by misalignment (geometry) of your tires. Poorly aligned tires reduce the control and performance of your tires. This is when the tread grooves have lost their depth.

What is a flat tire?

When block wear is uneven, such as uneven wear on a shoe sole, scaling occurs. For example, on a misaligned car, when one tire touches the ground more than another, the chance of having a flat tire increases.

When the inner or outer side wears out faster than the rest of the tire, wheel alignment is necessary. There is excessive camber in the front suspension, causing the wheel to lean too far in or out, putting too much load on one side of the tire.

When is the tire on the wire?

3. Exceeding the TWI limit (protrusion in the tire groove) is what indicates tire wear. … The appearance of the layer of wires, which requires the rapid replacement of the tire. However, the right thing is not to allow this to happen, as the tire can burst, as well as impair driving and braking.

What are the signs that the tire shows if it is used with high pressure?

On the other hand, in cases of high pressure, which means more air than the maximum supported, the biggest problem is the fact that the tire is more susceptible to cuts and impacts, making the car much worse to drive and changing the dynamics of vehicle stability.

How to disguise bald tire?

A grooved or beaded tire is nothing more than a tampered bald tire. A tire repairman from Porto Alegre shows the technique: with hot blades, he makes new grooves, on top of the almost erased original marks. “If I get the right blade from him, nobody notices”, says the tire repairman.

How to identify the tire’s TWI?

Firstly, at the bottom of the grooves they have the TWI (Tread Wear Indicator), an indicator of tread/tread wear, which if the tire has already touched them, then it is time to change it. If you haven’t noticed these indicators at the bottom of the grooves, know that the minimum groove thickness is 1.6 millimeters.

Why does the tire wear more than one side?

One of the main reasons that make the car spend more tire on one side than on the other is wheel misalignment, and there are several reasons that can cause this, such as the impact when falling into potholes, forcing the vehicle against the curb. , in addition to bushings, stops and even damaged springs or shock absorbers.

Which tire wears more right or left?

The recommended thing is to move the front to the rear with a maximum of 10 thousand kilometers and continue alternating. The front wears out three times faster than the rear, explains Quadrelli. “The difference in wear can generate imbalances between the axles in terms of handling and braking, especially in the wet.

Which side of the car tire wears the most?

Why do front tires wear out faster? It is inevitable that your vehicle will show uneven tire wear. One of the main factors for this is the higher consumption demanded by the tires installed in the front of the vehicle, which can degrade three times faster than the rear tires.

How many miles does a shock absorber last?

It can last up to 150,000 km and is only replaced even if it is damaged. The loss of car height, for example, indicates a problem with the spring. Also pay attention to your painting: if there is a crack or something that has damaged the paint, the piece can rust and have compromised durability.

Which tires are most important?
