If it is deviated, it will become straight, the relative grounding area will increase, and the sharp corners will have greater grip and handling. Therefore, many cars, especially those that pay more attention to handling, actually have obvious external characters, which is a design to improve handling, which is why many cars say that adjusting the chassis can improve the handling of the whole vehicle.
Extended data:
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.
The front wheel alignment has a great influence on the service life of the tire, especially the toe-in and camber of the front wheel. The camber of the front wheel will mainly accelerate the wear of the shoulder, that is, eccentric wear; Too small and too large toe-in of the front wheel is mainly to accelerate the wear inside and outside the tire.
