VEHICLES WITH LABOUR DISCLOSURE AND GROWTH-TIME-APPLICANT

摘要

A vehicle tire having a rotation time wear indicator associated with the tire tread which visually shows when the tire tread has worn to various levels at which levels the tire should be rotated to a different wheel position on a vehicle. The wear indicator is a plurality of pattern parts such as holes, raised portions in tread grooves or other distinctive patterns in the tread which are positioned at various radial levels of the tread with the different levels being spaced apart at different locations around the circumference of the tread. When the tread wear reaches various levels relative to the levels of the pattern parts, so that any particular pattern part is no longer visible, then it is time to rotate the tire to another wheel position.
