Pay attention to tire pressure
Air pressure is the key to tires. Too high or too low will shorten its service life. When the air pressure is too low, the deformation of the carcass will increase, and cracks will easily appear on the sidewall, and buckling and deflection will occur at the same time, which will lead to excessive heat generation, rubber aging, ply fatigue and cord breakage. Too low air pressure will also increase the contact area of the tire and accelerate the wear of the shoulder.
If the air pressure is too high, the tire cord will be excessively stretched and deformed, and the elasticity of the carcass will decrease, which will increase the load when the car is running. Once hit, it will cause internal cracking and explosion. At the same time, too high air pressure will accelerate tire crown wear and reduce rolling resistance.
