Wayne that motor is looking good . The tyres dont get glued together .I think I know what you mean. On each wheel there is a chrome ring that glues on to the wheel this is what holds the tyre on the wheel . Then the rear wheels glue together at the center then the hub goes through both the wheels and is glued at the back of the inner wheel at the hub .Make sure that you get the chrome off where you need to glue or they wont stick. I hope this helps you a bit .
