These black plastic wheels press-fit onto the 3mm D shafts on many of Pololu motors, including micro metal gearmotors and mini plastic gearmotors, to make a nice drive solution for small robots. The wheels have silicone tires and measure 90 mm (3.54″) in diameter. Six additional mounting holes for 4-40 screws make it possible to use the wheel with several of Pololu universal mounting hubs. The wheels are sold in pairs.
