RC4WD Z-W0166 Dick Cepek Torque 2.2 Internal Beadlock Wheels (4 Pack) - Heavy Duty Off-Road Wheels for RC Crawlers & Trail Trucks - Perfect for Rock Crawling and Off-Road Adventures

These were a pain in the a... had to modify the wheels just so they would fit. First off the center hole is too narrow for the nub of the 12mm hex to fit through; you will need to step drill the center hole do it's wider. 2nd is that if you plan on mounting a tire with a thicker sidewall you will need longer screws to prescrew to attach the wheels then replace them with the normal screws once the two sides are closer together. I would not recommend these wheels to anyone unless you like frustration
