Dunlop Geomax AT81 Tire 80/100x21 for Beta 390 RS 2015

AT81 rear tread block shape and distribution plus DIRTuitive Grip Design (DGD) knobs help the tire penetrate down through the surface dirt for extra traction across a broad range of off-road applications. Front tire construction includes two plies of nylon wrapped with a third ply of polyester for a strong base. Lateral grooves on the shoulder knobs provide additional biting edges and also allow the knobs to be more flexible.
