The 3.5" diameter tires are used on our 4WD Rover 1 robot chassis kit. The rim is made from nylon with a very sturdy design. They can be dyed to any color you want with RIT dye. Instructions for mounting the tires to the rims are included here. We recommend you use a thread lock, such as loctite on the 8-32 screw when using the HUB-05.
