I used 32mm Challenge tires on OpenPro rims for two years without issues. As Eric said, pressures are usually quite low relative to, say, 90psi+ for narrower tires. I went down to around 45psi many times and never over 60.laffingmonk said:Hi - First post here.
Anyone ever mounted 32c tires to Shimano 7801 wheels? Recommended tire width is 19-25.
