these are probably ******** questions, but:
1) if i were to run a 700X23 tube in a 700X22 tire, would i need to adjust the psi, or just fill as i would if it were a 700X23 tire? ( i normally keep my tires at about 115)
2) i have the same question but for a 700X23 tube in a 700X24 tire.
the reason i'm asking is i just bought a new tire set with these sizes, and want to use my old tubes.
