An endless rubber track belt includes an endless, elongate carcass having an outer surface, an inner surface, and at least one reinforcing layer. The inner surface defines a plurality of wheel path areas. A plurality of tread lugs are disposed on the outer surface. A plurality of guide lugs are disposed on the inner surface, where each guide lug includes oppositely disposed drive faces, an upper face between said drive faces, and oppositely disposed end faces. At least one reinforcement strip is disposed inward from the inner surface and outward from the at least one reinforcement layer. The at least one reinforcement strip is positioned adjacent the plurality of wheel path areas. The at least one reinforcement strip may include a bias ply formed of two layers of cords arranged in opposite +/− bias angles. The +/− bias angles may range from about +/−20° to about +/−80°.
