This is a pack of four black Kyosho 1/8 buggy spoked wheels. This is the same wheel type that comes stock with the Kyosho MP9, but can also be used with the previous generation Kyosho buggies, such as the Inferno 777 and 7.5. These wheels are made with a larger overall diameter than previous Kyosho wheels to eliminate sidewall flex from the tire and are made from harder plastic to eliminate wheel flex. The spoked design helps to keep dirt build up inside the wheel to a minimum, as well as allow you to see what the wheel is doing during braking.
