Want to make sure that what I think is, in fact, true. Recommended inflation pressure seems to come from the tires, not the tubes. My 700x38s carry 50-75 and I just read that someone with 700x32s says it's 110 for him.
So, is it all about the tube and not the tube? That essentially all tubes to fit such tires can handle much higher pressures than what the tire may be marked with? That the actual danger lies in the design of the tires sidewall and bead?
