Use on go karts or minibikes as a front wheel or rear wheel. Rims are two-piece for easy tire removal. Wheels include the bearings and nuts and bolts. Choose the bearing size to fit your axles outside diameter, either 5/8" or 3/4". These wheels fit tires and tubes with a 6" inside diameter (center hole). Example, a 410 x 350 x 6" tire fits these rims. The last number in the tire size (6") is the size tire that the wheel fits. The chart below shows all the different bearings available for this wheel. Find the bearings you want, if any, then click on Bearing Options above and select the appropriate part number. The corresponding price will then appear.
