What is?
refers to the air pressure within the air pressure of automobile tires, the tire pressure is normal life and tire performance play a critical role.

tire pressure and tire life
· pressure is too low or too high will shorten the tire life, the tire pressure is too low strain increases, the sidewall prone to cracks, flex movement generated simultaneously, resulting in excessive heating of the tire, accelerated aging of the rubber, and even puncture. Increased ground contact area of the tire, the acceleration shoulder wear. · Tire pressure is too high will cause the over-expansion, decreased flexibility, in case of a larger impact will burst, while pressure is too high will cause excessive wear a crown.

tire pressure and vehicle performance
· dynamic car driving on the road, must overcome rolling resistance from the ground, while the tire pressure great influence on the rolling resistance coefficient. · Rolling resistance coefficient decreases when the pressure increases, because the tire pressure decreases, the large deformation of the tire rolling resistance is increased, so that dynamic braking is reduced by a suitable reducing · tire pressure can be increased tire deformation, increased tire and the ground contact surface, thereby enhancing adhesion on the ground, in order to obtain a sufficient braking force to the ground, to ensure good braking. By the time of the · different road, tire pressure needs are not the same. inWhen the good road, try to make it up to standard pressure value when driving on loose surfaces, try to make some of the low atmospheric pressure, so as to avoid tire ROLLING phenomenon. · Load capacity load size depends on the level of car tire pressure. The higher the greater the load capacity of the tire pressure, tire pressure smaller load capacity decreases.

Further reading Standard Tire Pressure
of the vehicle tires generally identified in the driving position of the main fuel or door inner position of the cover, and They are labeled no-load and full-load two kinds of tire pressure.
In addition there are marked on each tire, in addition to numerous sidewall identification, but also marked with small print and the structure of the tire carcass and Caution, which tire is a tire pressure safety limit . The driver may be set by reference to standard tire pressure standard tire pressure.
