How to delay tire life

The service life of a tire is related to its own quality, but if the following points are achieved in use and storage, its mileage will be greatly improved.

1. Strictly control the tire temperature during driving. Kill

When the vehicle is running, because the tread and sidewall are constantly stretched and compressed, the rubber molecules and molecules, the cord and the rubber, the inner tire and the outer tire, the tire and the rim, and the tire and the road surface Between the friction and heat. The temperature of the tire will continue to rise during long-distance driving or driving in the hot summer, which will reduce the mechanical properties of the tire material, increase wear, and easily cause ply delamination and loose cord breakage. If the tire temperature rises to 95°C There is a danger of bursting.

Generally, when the tire temperature rises from 0 ℃ to 100 ℃, the strength of the Kaplan cord of the tire decreases by about 20%, while the strength of the rubber and its adsorption force with the cord decrease by about 50%. Therefore, it is necessary to ensure that the tire temperature does not exceed 90 ℃.

2. Master the tire inflation standard and ensure that the tire pressure is at the specified value.

Too low tire pressure will increase wear and tear and reduce mileage. When the tire pressure is lower than the standard value, the wear of the tire shoulder increases sharply; when the tire pressure is higher than the standard value, the tire contact area decreases and the unit pressure increases, which increases the wear in the middle of the tire tread and increases the tire rigidity At the same time, the dynamic load on the wheels increases, which is prone to carcass burst. The impact is more serious when driving on uneven roads or at high speeds.

3. Strictly control the load of tires and prohibit overloading.

Overloading will increase the deformation of the tire, increase the stress on the carcass, increase the contact area between the tread and the road surface, and increase the relative slip.

4. Maintain good vehicle steering, braking and driving mechanism technology.

If the toe and camber of the front wheels are too small, the inner edge of the tread will be severely worn; if the toe and camber are too large, the outer edge of the tread will be severely worn. Brake assembly is too tight, so that the tire rotation is not smooth and produce slip, drag, wear and increase. When the imbalance of the wheels is too large, the tie rod ball joint is loose, and the kingpin clearance is too large, the vibration of the steering wheel during driving will increase, and it will also accelerate the wear of the tires.

5. Reasonable selection and matching of tires

The tire size should be adapted to the vehicle type. If the size is too large, the propulsion force of the vehicle will be reduced, and if the size is too small, the tire will be overloaded. To consider the tire pattern shape, pattern height, old and new degree and road conditions and other factors, reasonable collocation, the implementation of tire rotation on schedule.

6, strictly abide by the driving rules.

Do not start too hard, try to avoid frequent braking and emergency braking. When turning and driving on bad roads, slow down appropriately. When overtaking obstacles, prevent the tires from partially deforming or scratching the tread. Do not park the car in a place where oil and steel slag gather, and do not turn the steering wheel after parking.

7. Do a good job in the storage of vehicle tires to prevent the tires from being exposed to rain and direct sunlight and accelerating aging.
