As a long time race mechanic and USCF official, I can testify that there are easy common sense steps to avoid having a tire roll off or fail due to adhesion problems. It is worth mentioning that there are high penalties for crashing in a race when it is determined that the tire rolled off or failed due to improper maintenance or installation.
The first key is to routinely inspect and test them. (doh!) Sidewall nicks, peeling base tape, old glue, separating treads, all can be visually seen or detected by the earlier mentioned testing by rolling the tire to the side with the heel of your hands. I have seen a tire come right off a rim at the starting line when tested by an official! Ironically, the rider is always indignant in these cases which is ridiculous as it is the riders responsibility to make sure his equipment is safe for himself and others!
Properly applied glue from any of the companies (Wolber, Clement, Vittoria, Conti, Fastack, etc.) works very well, but must be applied carefully in multiple coats and to both surfaces (rim & tire) and allowed to cure over night. I do think the tenacity of Fastack makes it tough to remove a tire when fixing a flat or whatever. More often than not, it tears the tire to pieces which may be unfortunate in some cases, so while that I don't think it is unsafe to use, I prefer not to use it. I am not fond of the baby poop brown Clement or Victoria for aesthetic reasons, and prefer Wolber and Continental...
I have successfully used Fastack and contact cement to re-attach treads & base tapes. I think base tape separation is caused by either water absorption and subsequent drying, or allowing tires to remain at high inflation ...
Water damage can be helped (not totally prevented though!) by painting the sides of the tires with liquid latex. We have talked about liquid latex here before. It is pretty cool stuff! It can be bought cheaply from carpet stores and needs to be thinned with water by approximately 1/2. Then paint it on and let dry.. as with all painting, two thin coats are always better than one blabby coat...
High pressure "peel off" of tapes can be helped by religiously deflating tires after every ride. Not to "flat", but to maybe 20-30 lbs. If the tape starts peeling, liquid latex or contact cement can nip it in the bud...
Hope that helps!
