Truck tyre for everyday use is concerned, pay attention to tire pressure problems. Some people think that tire is too full of cheer walls have not thought Truck tyre under-voltage problem, it is very one-sided. General car speed is very fast, Truck tyre's shape in a state of high-frequency alternating, less distortion will increase if the air pressure, tire tread pattern on both sides will be excessive wear, the matrix can not resist because of the pressure of the ground The distorted, resulting in high temperatures and accelerate Truck tyre wear and tear, eventually causing a puncture. If the pressure is too large Truck tyre will also lose their flexibility and excellent shock absorption, grip not only worse, the central cause excessive wear and tread depth tread uneven, Truck tyre at high speed there may not be under to excessive pressure of a tire blows out the expansion. Therefore Truck tyre tire pressure is too high or too low are dangerous, discounted air pressure problem. Shall require manufacturers to maintain the standard Truck tyre pressure, including spare tire air pressure. Self-measurement of tire pressure with a tire pressure measurement, but must state in the Truck tyre measured at room temperature, as measured in the thermal state of the result of tire is not accurate.
