Before you mount them, clean the insides really well. Soap and water works really well. Sometimes I use acetone which is really really good. After it dries, with the tires inside out, wrap two layers of duct tape around the tire. Just try to keep it in the middle. Now, turn the tires right side in and mount them.

Well, does anyone know of a clean way of taking off freshly glued tires then?

I think i am going to try using some kind of mesh on the inside, and then using CA glue adhering it.

I really don't know why tire manufacturers don't infuse a cheap fabric weave into the rubber. Big deal if price goes up a few dollars, better than having 45 records at speed. Not to mentions much better handling, they could prob make them lighter too.
