Several Reasons Affecting the Service Life of All-steel Radial Tire?
1. Air pressure is the main reason affecting the service life of all-steel radial tires
1) Air pressure is the main reason that affects the service life of all-steel radial tires (80% of the problems that occur during the use of tires are caused by air pressure.)
Low air pressure: The large amount of tread activity means large deformation, large heat generation, and increased wear and tear. At the same time, tire performance is correspondingly reduced. Shoulder hollow, carcass crushing, abnormal abrasion and spigot cracking are prone to happen.
High air pressure, scientifically increasing the air pressure can effectively increase the bearing capacity of the tire at little cost of service life of the tire. When the air pressure reaches a certain level, it reduces the elasticity and cushioning performance of the tire, and the tire body becomes rigid. Meanwhile, belt wire and carcass wire also increase. The balance shaft moves up, which increases the stress and worsens deformation of the sub-hole, which consequently causes the sub-hole to crack. High air pressure can also likely cause patterns to fall off quickly, as well as tire punctures and irregular wear.
2. Other reasons affecting the service life of all-steel radial tires
When the service life of normally used tire is 100%
Tire service life is 60% of the normal
Tire service life is 40% of the normal
5) Outside temperature
6) Tire temperature
30 degrees is supposedly the standard temperature value of tire, and wear resistance life is 100%
When the tire temperature is 50 degrees
wear resistance life is 80%
When the tire temperature is 70 degrees
wear resistance life is 70%
Temperature is one of the main reasons that affect the service life of tires.
The greater the sideslip angle is, the greater the wear and the higher the temperature are. Frequent sharp turns can easily cause zigzag cracks at the spigot.
The higher the instantaneous speed is before braking, the greater the amount of wear will be caused; the more frequent braking happens, the faster the temperature rises, and the greater the amount of wear will be caused.
