I use to mount all of my own tires and always just used Weldwood contact cement. Put a coat on the rim and a coat on the inside of the tire. Let dry for 15 minutes and then dunk both in a pan of laquer thinner and slip the donut on the rim. Very easy to do and the contact cement works way better than whatever is being used today by the mfg's. Be carefull of the CRC rims and lacquer thinner though.

One thing I have noticed is that the larger you run the newer tires, the easier it is to peel or chunk one. I typically cut my rears down to 43mm to start and have very few problems. The orange rears do hold up better than the yellow as they have yellow foam on the inside for forward traction and grey foam on the outter rim for durability and to free the car up in the corner a little.
