Passenger Car Tyres Temperature Change

Nov 02, 2017

Bus tires are one of the important parts of the bus, it is directly with the road contact, and bus suspension to ease the impact of bus driving, to ensure that the bus has a good ride comfort and ride comfort; to ensure that the wheels and pavement Good adhesion; to improve the traction of the bus, braking and through; bear the weight of the bus, the tire on the bus played an important role in more and more people's attention.


(1) Bus start can not be too much, both empty and heavy vehicles should be low-speed smooth start. Avoid tires and tows on the ground to reduce tread wear.

(2) on a good road, should keep straight forward, in addition to the car and avoid obstacles, prohibit left and right swing and sharp turn to prevent tires and rims between the horizontal cutting damage tires.

(3) vehicles under the long slope should be based on the slope size, length and road conditions, the appropriate control of speed. In the case of long slope, steep road, complex road conditions, should be hanging gear, and the use of a slight brake control speed downhill, so not only to avoid emergency braking, reduce tire wear, but also safe driving is also guaranteed.

(4) vehicles uphill, should make use of inertia, timely speed, timely shift, uphill to keep the vehicle after the appropriate spare capacity, do not wait for the car to stop and then start to reduce tire wear.

(5) Driving turns should control the speed according to the curve, do not turn high speed, otherwise the vehicle produces a large centrifugal force, so that the vehicle cargo tilt, center of gravity offset side, unilateral tire overload drag, Was cut off by copper, causing damage.

(6) in the complex circumstances (will be car, overtaking, through the town, crossroads, over the railway) should be the appropriate driving speed, reduce frequent braking and to avoid emergency braking, or between the tire and the ground Sliding friction, resulting in severe tread wear.

(7) in the bad road should be slowed down, and carefully observed, through the road, after the parking should be checked whether the twins are sand, if any should be promptly excluded.

(8) vehicles on the way parking and parking, to develop a safe taxiing parking habits. In the parking before the choice of ground leveling, clean and oil-free ground parking, each tire should be a smooth landing, especially the vehicle loading overnight, should pay attention to choose a good place to park, if necessary, the rear wheel up.

In order to avoid these abnormal wear conditions, we should pay attention to the following matters:

1, pay attention to tire pressure.

Pneumatic pressure is the tire of the door, too high and too low will shorten its life. The pressure is too low, the carcass deformation increases, the sidewall prone to cracks, while the resulting flexion, resulting in excessive heat, to promote the aging of rubber, ply fatigue, cord broken. Air pressure is too low, but also increase the tire ground area to accelerate the shoulder wear. Pressure is too high, will make the tire cord by excessive deformation, the carcass elasticity of the decline in the bus in the load by the increase, in case of impact will produce cracks and blasting, while high pressure will accelerate the crown Wear, and to improve the performance of rolling resistance.

2, regularly check the front wheel positioning.

The front wheel positioning has a greater impact on the service life of the tire, especially the front wheel front and front wheel camouflage as the main factor. Front wheel eccentricity will mainly accelerate the wear of the shoulder that is partial wear; front wheel front beam too small is too large to accelerate the tire inside and outside the wear and tear.

3 master the tire temperature changes

Hot weather traffic, due to the higher temperature outside the tire, the tire heat dissipation difficult, due to the speed, long distance, poor road conditions and other reasons, the tire temperature rose sharply, the tire pressure also increased, thereby accelerating the aging of rubber, Line and rubber adhesion, resulting in ply hollow or blasting damage, so hot weather traffic should pay attention to control the tire temperature. In the heat when driving, in addition to the appropriate reduction in speed, the conditions can be in the morning and evening when the temperature is low when driving, or the vehicle driving a certain distance after the parking break to prevent tire temperature is too high. It is strictly forbidden to use deflated antihypertensive practice because the tire deformation increases after deflating, which causes the tire temperature to rise and finally the tire is damaged by overheating. In the low temperature season, because the tire in the use of heat dissipation fast, not easy to produce high fever, tread more wearable. In the low temperature season, especially in cold weather, vehicles overnight or after a long time after parking, in order to improve the tire temperature, it is best to start in the first few kilometers to low speed driving is appropriate. Therefore, it is important to master the temperature change in tire travel.
