1. A tire comprising:
- a pair of sidewalls;
a circumferential tread constructed of a base rubber, the circumferential tread having a plurality of bars and a plurality of valleys disposed between the plurality of bars;
a first fabric reinforcement layer disposed on the circumferential tread, such that the first fabric reinforcement layer covers the plurality of bars and the plurality of valleys, the first fabric reinforcement layer having a first color; and
a second fabric reinforcement layer disposed on the first fabric reinforcement layer, such that the second fabric reinforcement layer covers the first fabric reinforcement layer, the second fabric reinforcement layer having a second color different than the first color so as to facilitate visual detection of wear of the tire,wherein at least one of the first and second fabric reinforcement layers has a hardness that is at least 10% greater than the hardness of the base rubber.

Abstract
A tire includes a circumferential tread constructed of a base material. The circumferential tread has a plurality of bars, each of the plurality of bars having a top surface and a plurality of side surfaces. The circumferential tread further has a plurality of valleys disposed between the plurality of bars. A reinforcement layer covers at least some of the plurality of valleys and an outer layer covers at least a portion of the reinforcement layer.
