I have a 1978 Raleigh Competition GS with its original 700 Weinmann rims and am having a difficult time finding tires that will not pop off the rims moments after inflating. I bought some Cheng Shin tires (700 X 25) from Nashbar that worked beautifully, but I can't find them in a 25 width anymore. So, I tried a Panaracer Pasela tire (700 X 25) with a wire bead purchased from Harris Cyclery. However, it won't stay on the rim, even with the air pressure reduced to 80 psi (the tire sidewall says to inflate to 115 psi).
1) Anyone know where I can purchase a tire that can be safely inflated on my Weinmann rims?
2) Are there any tricks I should try to keep the Panaracer tire on the rim?
3) Can a 700 X 23 tire be used on a rim designed for a 700 X 25 tire? I can find 700 X 23 Cheng Shin tires.
Thanks and regards,
