4. Should I adjust the tire position?

Because the weight of the car body is not evenly distributed among the four tires, frequent transposition definitely helps to ensure the uniform wear of the tires, thereby extending the service life of the tires. Please follow the vehicle manufacturer's tire adjustment recommendations in the "Vehicle User Manual". If the manufacturer does not specify a specific tire adjustment period, usually front-wheel-drive vehicles should be replaced every 8,000 kilometers, while four-wheel-drive vehicles require Change positions every 6,000 kilometers. The first adjustment of the vehicle is the most important. The inflation pressure of the tire during tire adjustment must follow the manufacturer's recommendations. The specific methods are as follows:

Rear-wheel or four-wheel drive vehicles: adjust left front to the right rear, right front to the left rear, left rear to left front, right rear to right front;

Front-wheel drive vehicles: adjust left rear to right front, right rear to left front, left front to the left rear, right front to the right rear

The positioning method of single guide tires is different from this. For example, Goodyear Ducaro GDi, Eagle Ventura and Eagle F1, etc., can only adjust the front and rear wheels in a straight direction, and cannot cross left and right.

If your vehicle is a four-wheel drive, China International Tire Fair recommends that all front, rear and left and right wheels are cross-swapped, that is, left front to right, right front to left, left rear to right, right rear To the front left.

If the spare tire on the car is the same size tire, you can also join the swap. In addition to swapping the left front/left rear with each other, please move the spare tire to the front right, front right to rear right, rear right wheel. Become a spare tire rest.

Uneven tire wear may also be caused by improper positioning or mechanical problems.

5. What is positioning?

When the vehicle's suspension system and driving system are in a standard state, and the tire and the rim run straight, we call the car correctly positioned, which can effectively ensure the uniform wear of the tire and the steering precision.

If the vehicle hits a road cliff or drives on rough roads, the positioning will be destroyed. Poor positioning will cause uneven tire wear and rapid wear. In addition to regular inspections as required, when you notice irregular wear on the front or rear wheels of the vehicle, or abnormal handling performance or steering response of the vehicle (eg, deviation or bumps), be sure to do a positioning check. Depending on the symptoms of the vehicle, you can choose "front-end" positioning or "four-wheel" positioning. The money you spend on the positioning is totally worth it because good positioning can extend the life of the tires, improve performance, and can Improve comfort.

6. Is it safe to repair leaky tires?

China international Auto wheel show reminds you: If the tires show a lot of air leakage, they must be removed immediately for a thorough inspection to confirm whether the carcass is damaged. A flat tire can be damaged even for a short distance and cannot be repaired. Most of the tread needle punches, nail holes, or cuts less than 6 mm can be repaired by trained professional technicians. However, tire punctures larger than 6 mm and any sidewall punctures, as well as tires with a remaining groove depth less than 1.6 mm, must not be repaired. Once the tire is found damaged, the safest way is to replace the spare tire. For your driving safety, be sure to check the tire pressure and appearance regularly.

7. Will the tires be corroded?

Sunlight, oil, acids, and hydrocarbons can attack tires. All tires should be stored in a cool, dry and darkroom to avoid the risk of moisture deposits in the tires. Organic matter and sunlight will cause the chemical reaction of the tire rubber, resulting in shortened tire life or reduced performance.
