Summer Tires Are Afraid Of Heat-proof Guide - Tires, Maintenance - Auto Repair And Maintenance
Temperature rose gradually, hot weather, cars Tire As the temperature began to get restless
. According to relevant data, traffic accident occurred on the highway, because Puncture Accidents caused by accounting for over 70%. The main reason is that flat tire caused the tire temperature, tire material mechanical performance. How to prevent car flat tire, raise Travel Security has become the most critical issues, summed up the industry to prevent car puncture method, for your reference.

Recent years, the performance of cars and tires have a very elevated to require tire speed rating and the maximum speed to match the capacity of the tire quality and compatible with the set. According to GB2978-89 "car tire" series provides car tires with a total of 10 speed signs LH symbols and the maximum speed corresponding to the different rim diameter tires have a maximum speed of corresponding regulations. The capacity of the tire, now widely used internationally, "load index" notation. Such as the sidewall is marked with 9.00R20140/137, that a single tire load index for the 140, load value of 2500kg; twin load index was 137, the load value of 2300kg.
2 to maintain the correct tire pressure
Tire tire inflation pressure is to determine the life and work of the main factors of good or bad. Pressure is too low, the matrix deformation increases, resulting in increased internal stress, and excessive heat to heat up, accelerate rubber aging and tire cord fatigue, resulting in cord broken loose and ply delamination; tire pressure is too high, the cord over tension, increased tire stiffness, dynamic load increases, easy to produce burst tire crown. Therefore, the use must be strictly in accordance with standard front and rear wheels under manual pressure to inflation.
3, to prevent tire overloading overloading traffic
Overload driving, the tire deformation increases, cord and cord stress increases, making it easy cord broken loose and ply delamination, while the contact area increases due to an increase of fetal shoulder Wear and tear , Especially in the face of shocks, it will cause tire burst crown. Must be in accordance with the calibration of the capacity of many passenger loading, and pay attention to cargo load balancing, vehicles in place to prevent the movement of goods and tilt, causing the tire to bear the load due to traffic accidents caused by uneven.
4, to prevent speeding High speed because of friction between tire and road surface increase, the load increased, the frequency increases tire flexing, tire temperature and internal pressure to rise, likely to accelerate rubber aging and tire cord cord fatigue or even early delamination and blasting, to shorten tire life, prone to traffic accidents. Therefore, the need to avoid prolonged high speeds, in strict accordance with the highest set speed highway driving, speeding is strictly prohibited.
5, with vertical pattern of the radial tire
Radial tire strength, carrying capacity, rolling resistance, good adhesion, slip tread less heat low, matrix thin, heat dissipation, low running temperature. Vertical pattern of tire rolling resistance, due to friction between tire and road heat generated less heat dissipation.
Six, not to use excessive tire wear and tire retreading
According to GB1191-89 ,9743-9744-88T and GB516-89 requirements, the tire should be set equidistant along the circumference of not less than four of the wear mark, when the tire wear to here, the tread groove disconnect , that tire is no longer used. If continued use will cause excessive tire wear, easy to cause a puncture due to decreased strength. Renovation of the balance of births, poor uniformity, and easy to make high temperature reduces the strength cord, affecting the ride comfort, making the tread wear increased, the temperature rise.
7, to keep the chassis a good technical condition, maintenance of the tires in good time
If the chassis technology in poor condition, such as the front wheel misalignment, wheel imbalance, axle or frame deformation, such as leaf springs to improper installation vehicle handling and stability will deteriorate, the car would swing in motion occurred to increase tire wear, easy to cause traffic accidents. Chassis should be maintained good technical condition, in a timely manner and tire balancing tire conversion work.
