PURPOSE: To provide a method and apparatus for grinding tires in order to avoid the exponential increase of the rate of wear when signs of abnormal wear appear, or to decrease the rate of wear when the tire has molding defects. CONSTITUTION: In order to grind a tire 2 mounted on a vehicle, an abrasive belt 5 is used which is stretched over rollers 51, 52, 53, 54 and 46 which are mounted on a frame 4. By the action of a jack 7, the tire 2 is released of all loads. A counterweight 45 urges the frame 4 towards the tire 2. The supporting force with which the abrasive belt 5 rests on the tire 2 can be adjusted to a very low value. |
