The complex road conditions of long -distance and off -road cycling can easily lead to the fragments of tires.

First observe whether the crack is on the front of the tire or the side. If it is on the side, you need to change the tire immediately; if it is on the front, the crack does not exceed 0.5cm, temporarily use a dedicated repairs to repair the cracks (for example, Parktool has such a type product).

There is a standard pressure value on the outer tire. For ordinary rider, the tire pressure is recommended to be up to 140 PSI ~ the minimum 120 PSI. This pressure value comes from the test. It will increase the rolling resistance when it exceeds 140 PSI. In addition, when the road conditions are poor, it is recommended to go around slowly.
