Car TPMS Problem

Tire pressure is insufficient, although the feeling of the tread contact with a larger area, but in fact the tire section in the limit state, showing a concave state. Therefore, in the two tests, the braking performance than the normal low pressure tire pressure difference. And under high pressure, the tire section which presents a convex shape, so that the contact area is less. From the cross-sectional area can see the tire contact with the ground contact area, if prolonged use of high pressure and low pressure with the tire wear will result in bias.

When pressure is too high, the tread presents "convex" shape, and therefore less tire contact area. And when tire pressure is too low, decrease sidewall support force, not only a sense of control of the steering wheel becomes blurred, will directly affect the handling characteristics of the tire. So only under normal atmospheric pressure to achieve the best handling performance of the tire and the vehicle.

Q: Who mute better?

A: Results and fuel consumption consistent, high pressure slightly better acoustics

Mute test, believed to have experienced cyclists will guess the test results, a larger contact area of low pressure big noise, and the contact area of high pressure and less noise. The test at a speed of 80km / h on the same road driving, noise meter is measured under the same results, high-pressure state to 61.6 db win.
