my first reaction was two things: 1.) i agree with bill and peter that 60psi is high. i usually go no higher than 40 on compass rat traps (measure 50mm), and they need a bit more pressure because the sidewalls are supple 2.) for stiffer / tires with wirebead, i go lower pressure. i blew off the tube and sidewall of some 650bx42 pasela wirebeads, with 40psi front (generally what I inflate Hetres to). i'm a 155lb rider 3.) could also be changing pressure from changing temperature
