8 signs to know to change car tires at the right time

(Baonghean.vn) - Car tires are extremely important parts. To ensure safety when driving and save costs on replacing this part, car users need to know how to determine the wear and tear and replace tires when necessary.

1. Apply manufacturer standards

Every tire has a tread or tread pattern, the main function of which is to conduct water to improve traction and prevent hydroplaning on wet roads. According to most manufacturers' standards, a tread depth of less than 1.6 mm means the tire is worn and unsafe.

2. Based on the number of kilometers traveled

Depending on the type of tire and brand, tires have different durability; therefore, you need to consult the manufacturer's advice for the number of kilometers the tire can withstand.

Normally, motorcycle tires usually have a lifespan of about 15,000 km, with the road conditions being standard and flat. If you often travel on bumpy, rocky roads... then the tire lifespan will be shorter. Therefore, depending on the type of road the vehicle often travels, depending on the type of tire to estimate the tire lifespan.

3. Depth of grooves

Each tire has a logo embossed on the side of the tire, indicating the location of the tire wear indicators in each main groove of the tire surface. The tire wear warning is a small raised edge at the bottom of the tire tread grooves (tire tread). Normally, the grooves of the tire tread have the lowest allowable depth and reach the safety limit of 1.6mm. If the tire thickness is lower than this limit, you need to replace the tire immediately to ensure safety.

4.Bulges or bulges on the tire sidewall

Sometimes the sidewall is the first place to wear out. This results in blisters or peeling on the sidewall. These can cause the tire to suddenly explode. Therefore, if you do not replace the tire as soon as you notice a blister or peeling, the risk of a serious accident is very high.

5. The wear indicator bar begins to appear.

Modern tires have a valuable feature that older tires didn’t have: tread wear indicators located under the grooves. These are small rubber ridges located under the grooves, and are not visible (or difficult to see) when the tire is new.

After a period of driving, they will gradually appear. When 1 or 2 of these bars can be clearly seen, it is usually time to replace the tire.

6. Cracks appear

Not all signs appear on the tire surface - they are also concentrated on the sidewall. Due to changes in pressure, tires can develop small cracks on the sidewall surface.

In addition, during operation, the tire may rub against sharp edges somewhere or sharp gravel may fly up, causing cuts. If these marks appear too much or too large - this is the time you should not "regret" the old tire and replace it with a new one as soon as possible.

7. Steering wheel shaking

When driving, steering wheel vibration is inevitable, especially when moving on gravel roads. However, after a while of driving, you will train your conditioned reflexes and be able to recognize what vibration is abnormal.

There are many reasons why the steering wheel of a car vibrates a lot, but nIf the tire is worn unevenly, the driver may feel vibration in the steering wheel while driving. At this point, the vehicle should be inspected and balanced. After checking and balancing the tire, if the steering wheel still vibrates, the tire should be replaced soon.

8. Tire expiration date

The National Highway Traffic Safety Administration recommends replacing tires every six years. Tires have symbols and indicators to guide users when to replace them under normal use without any problems.

After 5 years or more of use, inspection must be carried out at least once a year. If necessary, follow the manufacturer's recommendations when replacing the tires that come with the vehicle.
