Tire Glue???

I use denat alcohol to clean the tire bead with and rid them of the mould release stuff they come coated with. Motor spray or contact cleaner works well also. I wipe each bead down twice. If the wheel is chrome where the tire is going to be glued, I use my dremel and scuff the chrome up good - CA has hard time sticking to the chrome finish they put on wheels. For non-chrome, I use a piece of 220grit paper and dull the finish where the bead will glue down.

I use the med losi tire glue and have never had a tire come loose.
