*WTB's tire pressure recommendations have changed over time due to further developments in technology. Riders may always reference the markings on their tires for allowed pressures ranges, but may also consult wtb.com for the most up-to-date tire pressure recommendations from WTB. We calculate pressure recommendations based on an average rider weight of 160-180 lbs and suggest increasing our minimum recommended pressure on WTB.com by 2-3psi for every additional 10 lbs of rider weight. Never exceed the maximum tire pressure marked on a tire.
