Because the air pressure is the life of the tire, the inflation pressure of the tire must meet the national standards for different types of tires, specifications of the specified air pressure.
Always check the air pressure of the tire, too high and insufficient air pressure will produce profile-shaped wear, pattern groove bottom crack, cord break, cord delamination, tire blasting and other damage; If you want to continue to drive at high speed, the air pressure should be increased by 5%-10% on the standard air pressure; At the same time, after the tire is driven, the internal gas will rise due to the rise in temperature, and the air can not be deflated at this time.
If the vacuum tire is worn too thin, or often insufficient air on both sides of the tire wall fatigue wrinkles are easy to burst.
When the vacuum tire is inflated, as the tire expands, the tire will press the wheel more and more tightly to ensure the seal. In addition, for the wheel, the processing is relatively smooth at the inclined surface, and the precision of the size is also very high.
