Is the front wheel pressure PSI37.5 high?

Front wheel pressure PSI37.5 is high. Now, many tires are not inflated. For these tires, the requirements of tire pressure are strict, tire inflation is related to seasonal changes, tire pressure is closely related to the performance of the car, such as comfort, bearing capacity, etc., which will also affect tire life.

Air pressure is the key to tires. Too high or too low air pressure will shorten the service life of tires. If the air pressure is too low, it will increase the deformation of the carcass, and cracks will easily appear on the sidewall. At the same time, it will cause overheating, promote rubber aging, tire cord fatigue and cord breakage. It 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.

Relationship between tire pressure and vehicle power and ride comfort

When a car runs at a constant speed on a horizontal road, it must overcome the rolling resistance from the ground and the resistance from the air, and the tire pressure has a great influence on the rolling resistance coefficient. When the air pressure decreases, the rolling resistance coefficient increases rapidly, because when the tire air pressure decreases, the rolling tire deforms greatly and the hysteresis loss increases.

Therefore, the appropriate tire pressure is the guarantee of good dynamic performance of the car, and the ride comfort of the car is directly related to the comfort of the drivers and passengers. In fact, the way of inflating tires has greatly improved the ride comfort of cars. Imagine that if the tires are made of rigid tires or solid elastic tires, their comfort will definitely be greatly reduced.

Then improper selection of pneumatic tire pressure will also reduce its comfort. If the air pressure is too high, the tire rigidity will increase, the vehicle vibration frequency will increase, and the ride comfort will become worse. If the air pressure is too low, the ride comfort will be better.
