Reason for purchase
Without him, I have long wanted to buy it. I have been dismissed. As a result, I have a return trip…
This is indeed very dangerous. It is recommended that everyone pay more attention to the lower tire pressure and safely go home safely to pick up the hand.
Hazard of excessive tire pressure
a. The friction and adhesion of the tire will decrease, affecting the braking effect;
b. The steering wheel is shaken and deflected to reduce the comfort of driving;
c. Accelerate the local wear of the pattern in the center of the tire tread, so that the life of the tire is down;
d. The vibration of the body becomes large, which indirectly affects the life of other parts;
e. The tire cord is subjected to excessive stretching deformation, and the elasticity of the carcass is lowered, so that the load on the vehicle during driving is increased;
f. Decrease the rolling resistance. When encountering sharp objects such as nails and glass on the road surface, it is easy to get stuck in the tire, and the impact will cause internal cracking and blasting, resulting in a puncture.
Hazard of low tire pressure
a. The coefficient of friction with the road surface will increase and the fuel consumption will increase;
b. The steering wheel is very heavy, easy to run off and other factors that are not good for driving safety;
c. Increasing the amount of movement of various parts of the tire, excessive rolling causes abnormal heating of the tire;
d. The function of the cord and the rubber is lowered, causing delamination or excessive friction between the cord and the rim to cause damage to the bead portion and abnormal wear;
e. The friction between the tire and the ground is multiplied, the tire temperature rises sharply, the tire becomes soft, and the strength drops sharply. When the vehicle is driving at a high speed, it may cause a puncture;
f. If the tire pressure is too low, the carcass deformation will increase, the sidewall will be prone to cracks, and at the same time, the flexing motion will cause excessive heating, which will cause the rubber to age, the ply fatigue, the cord to break, and the tire grounding area will increase. Accelerate shoulder wear.
