ABSTRACT:
The present invention overcomes several disadvantages in conventional tires by providing a non-marking surface to the tire. The tire can be a pneumatic bias tire having a pair of parallel annular beads, at least one carcass ply wrapped around the beads, a non-marking tread cap, a tread base and sidewalls. A colorant may be added to the composition of the tread cap to create a tire having a colored, non-marking tread cap.
