Got told to air down to 15 PSI on the Rubicon and thought the guy was nuts
A buddy of mine who's been running trails in the Sierra for 20 years told me to drop my tires to 15 PSI before hitting the Rubicon last summer. I argued with him, said I'd get a bead leak or tear a sidewall on those granite slabs. He just shrugged and said try it or spend the day bouncing off rocks. Well I went down to 18 PSI instead, and after three miles I was bouncing all over, losing traction on the steep stuff. Finally aired down to 15 at the next pullout and holy cow the difference was night and day, crawled right over stuff that had me spinning before. So is 15 PSI really the sweet spot for big granite trails, or was that just the right call for that specific setup on my 35s?
