  • There are many duplicate questions on this SE -- use the search feature to find them. In short, you're going to have to experiment (depending on tire size, riding conditions, personal preference, etc). The pressure you should run will be significantly lower than whats written on the tire sidewall, typically, though. – Batman Apr 11 '15 at 19:32
