As the only part of the car in contact with the ground, the performance of the tire directly affects the safety of the driver and passengers of the vehicle, and the importance of tire performance can be imagined. With the rapid development of the automotive industry, consumers have begun to pay attention to the comfort, handling stability, NVH and other performance of the whole vehicle in addition to the safety performance of tires.
The first category is the safety performance required by regulations: high speed, durability, detachment, strength, and outer edge size;
The second category, the performance from tire assembly to vehicle testing: comfort, handling stability, NVH, fuel economy, impact resistance, dry and wet braking performance, wear performance, etc.;
The third category is a single tire performance test for the purpose of studying the performance of the tire monomer or the tire performance assembled on the whole vehicle: static ground pressure distribution, rolling resistance, tire rigidity, tire cell noise, tire mode, PRAT, six-component force test, odor, air tightness, environmental protection, tire dynamic balance uniformity, etc.
