Air pressure is overlarge or insufficient which will cause the damage to the tires
1) Air pressure of the tire reduces because of the unaffected leakage. One should use the barometer to check up air pressure periodically (once a month) in cooling condition before driving. Please adjust for air pressure specified by auto makers.
2)When driving, air pressure will increase, due to heat caused by the tires. And never let out the increasing portion of air pressure. After the tires cooling, air pressure will restore.
3) Please use the barometer to check up the air pressure, because it’s very difficult to make sure that the air pressure of the flat tire is insufficient with naked eyes.
4) In the event of using the four back tires, please add the same pressure.
5) To prevent leakage of valves and check valves (Coat with suds to make sure whether it leaks air), please be sure that you cover the valve bonnet.
6) Please don't forget to check whether the lugs of the rim are abnormal deformation.
TIPS: In order to ensure the economy and safety of the tire, please rotate the tires.
TIPS: When the tire wear limitation reaches the indicating lump, please replace a tire.
TIPS: When the tire wear limitation reaches the indicating lump, please replace a tire.
    Please confirm whether the cracks generate in the tires, or whether the tires are stabbed by the nails, metals, glass etc, or whether there are stones or other foreign material in the groove. When finding the foreign material, please consult with the tire stores and then get rid of it. If the depth of the rubber cracks caused by the outer damage reaches the cord, please do not continue to use it, because of the risk of the tires' troubles. About whether they can be repaired, please consult with the tire store.
    The use limitation of tires means that the residual ditch is 1.6mm, if over 1.6mm, please replace the new tires! These tires whose treads are worn and the grooves become shallow will lower the performance of the drainage and easy to skid. Therefore, when the tires have more worn patterns and at the same time driving in the rainy wet roads, it’s easy to face the danger of skidding.

    Because the installation position and direction of rotation are different, and because the stress of the tires’ contact patch are different, so the tire wear is different and the tire wear is also uniform. Used in the same position for a long term, the tire will come up foreign wear. The tire life will become short, and the vibration and noise will increase.
