Remove it first to see whether it is the side of the bite or the ring along the side of the bite, most of the side of the bite, the side of the bite to see whether the strip and the ring rust, if there is a hammer to knock off, in addition to see whether the outer tire mouth is a vertical plane, if not flat with a sickle, some of the mouth is very rotten direct front and back exchange, install the tire.

       There is also the fact that when the steel ring is installed, the tire is not installed in the end, which is difficult to press in the installation of the strip. The solution is to cut a circle of the tire mouth (do not cut too thick), or stand the tire and hammer the low edge of the steel ring to knock in, so that the lamination is also installed.

       Then there are some large vehicles that run hot and lack of water, and the tire mouth is scalded and deformed, most of them are scalded along the side of the steel rim, directly cut a circle, and the front and back are replaced. In addition, large vehicles should use double cushion belts. Use a standard 85, one big, one small, anything wider or thicker will bite.
