Speed restriction
Increasing the speed of the vehicle, especially when it is often driven at a high speed, the service life of the tire is significantly reduced. Because when the vehicle is driving fast, the more contact the tire has with the ground in a unit of time, the more frequent the friction, and the more the deformation frequency of the tire is increased. At this time, the circumferential and lateral distortion of the carcass is also increased. When the speed reaches the critical speed, the vibration of the crown surface appears as a wave deformation, forming a static wave. This static wave can lead to tire blasting a few minutes after its generation, which is due to the hysteresis loss caused by the tire deformation too late to recover, and its size is related to the time of load action, the faster the speed, the shorter the time, most of the kinetic energy is absorbed into heat, thus increasing the tire temperature, accelerating the aging of rubber and reducing the fatigue resistance of the cord layer. Tires are therefore prone to empty or burst, so limiting driving speed is very important.
Drive according to road conditions
The type and condition of the road surface have a great impact on the service life of the tire, and the driver should choose the road surface according to the road conditions and master the appropriate driving speed, which has a positive effect on increasing the mileage of the tire.
The vehicle driving on the flat, spacious and good vision of the road, such as highways, national highway lines and provincial highway lines, can be based on the technical conditions of the vehicle itself and the performance of the tire to improve the speed, but it should not be too high, otherwise it will affect driving safety and reduce the service life of the tire. Driving on uneven gravel roads and mining roads, due to the exposure of sharp stones or sharp roadside stones, easy to damage the tires. When choosing the road surface, pay attention to it and drive at a lower speed to prevent tire blasting damage.
Keep track of tire temperature changes
When driving in hot weather, in addition to reducing the speed properly, if conditions are available, you can drive in the morning and evening when the temperature is low, or stop and rest after the vehicle travels a certain distance to prevent the tire temperature from being too high. It is strictly prohibited to use the practice of deflating pressure, because the tire deformation increases after deflating, the tire temperature will rise, and finally, the tire will be damaged due to overheating.
In the season of low temperatures, especially in cold weather, when the vehicle is re-driving overnight or after a long time of parking, in order to improve the tire temperature, it is best to drive at a low speed for the first few kilometers after starting. Therefore, it is very important to master the temperature change during tire driving.
Use proper driving methods
(1) The car can not start too fast; whether empty or heavy, cars should start smoothly at low speed. Avoid dragging the tire against the ground to reduce tread wear.
(2) Driving on a good road, keep a straight line forward, in addition to the car, and avoid obstacles, prohibit the left and right swing and sharp turning, to prevent the tire and the rim from being cut by the transverse cutting damage.
(3) When the vehicle goes down a long slope, the speed should be properly controlled according to the slope size, length, and road conditions. In the case of a long slope, a steep road, and complex road conditions, it should be in gear and use slight braking to control the speed downhill, which can not only avoid emergency braking, reduce tire wear, but also ensure safe driving.
(4) When the vehicle is going uphill, it should try to make use of inertia, timely speed change, timely shift, and keep the vehicle with appropriate spare power when going uphill, and do not wait for the car to stop and start again to reduce tire wear.
The driver should control the speed according to the curve situation, do not turn at high speed, otherwise the vehicle produces a large centrifugal force, so that the vehicle's goods tilt, the center of mass offset to one side, unilateral tire overload drag, accelerate wear, but also make the tire by the wheel copper transverse cutting, causing damage.
(6) When driving in complex situations (meeting, overtaking, passing through towns, intersections, and railways), the appropriate driving speed should be mastered to reduce frequent braking and avoid emergency braking; otherwise, the sliding friction between the tire and the ground will cause serious tread wear.
(7) Should slow down on the bad road, and carefully observe, choose the way through, after passing, should stop to check whether there are stones between the twins, if there are, should timely exclusion.
(8) Parking on the way and parking on the scene, to develop the parking habit of safe taxi. Before parking, choose a flat, clean, and oil-free ground to park; each tire should land smoothly, especially when the vehicle is loaded overnight. Pay attention to choosing a good parking place, and lift the rear wheel if necessary.
