Another thing too, you can wet your foams to bring the shape back in but wait until they are fully dry before placing them in the tires. Too, be sure to wash your wheels and tires with a mild soap or denatured alcohol to get all the releasing agents from the factory off. If you want to keep them from ballooning at high RPM's then you can use simple strips of duct tape on the insides of the tires as well plus your foams, often referred to as belting, I did this with my Savage and LST's aftermarket tires and it did help out quite a bit. There is little to no difference in tire CA and krazy glue except there consistancies. I do prefer the Team Losi glues more so than any out there, I don't know why, but it seems to hold the best in the cases where I used it. Just be sure to clean where the tire meets the rim though, this will help it out alot in the bonding process for sure though. Good luck.
