The GMPW wheel is made to match the Solarbotics GM2, GM3, GM8, and GM9 gearmotors, and it also match the Pololu plastic gearmotors. This plastic wheel is molded from ABS and has a molded-on thermoplastic silicone tire with great traction and wear characteristics. There is a 64-stripe encoder pattern on one side of the wheel compatible with the Wheel Watcher. The plastic wheel measures just under 2-5/8" (69 mm) across by 0.3" (7.62 mm) wide and is available in blue, yellow, red, and black.

(For mini-sumo robots, you can also try using the high-traction sticky tire, which is NOT made to fit this plastic robot wheel, but happens to work pretty well with it.)
