Two things I have against the ride on tire balancer and sealant is the fact that if my tire is punctured, I want to know it and get it off my bike and put a new one in its place. Your life depends on those two pieces of rubber and if one is hurt and you don't know it you could lose it in a heartbeat at 80 mph on the freeway. Second is the fact that your tire changer isn't going to be happy with the extreme mess you just gave him when changing the tire to a new one.
