What kind of glue are you using? I used Fusion glue by Racers Edge for a while but now I am trying the AKA glue. The Fusion is so thin it wicks right around making glueing a tire real easy. The AKA is medium and requires longer but I am hoping it will make a better bond.
One track I go to frequently has a big sweeper at the end of the straight and keeping the tires on the rim is a challenge. Even with the best glue job they get peeled back. You can see rubber is still stuck to the wheel but its ripped away. I usually alternate a couple of sets and reglue them frequently.
The GRP premounts were the only thing I knew would be reliable in 1 hour long mains at that track. I hear they use Loctite 406 glue which is what I heard the AKA glue is.
