All BT series wheels compatible.
Available in 4 colors: sapphire blue, gun-metal gray, satin black, and Bullite red.
Bullite is the strongest wheels in the market. Especially in Utra 4, after hit many rocks, we have never had a bullite wheel crack or break once.ZACK POLLARDKing of Hammers Racer
Bullite fit tires perfectly and easy to install. Even as a beginner, that is no problem.GEORGEOwner of George Garage
