Rene Herse 27.5" x 2.2" (650B x 55) Umtanum Ridge TC Tire - Endurance (dark tan)

The Rene Herse Umtanum Ridge TC is a 27.5 x 2.2 in (650B x 55mm) knobby tire for gravel and mountain riders who want a fast-rolling tread that stays quiet on hardpack. A staggered-block, noise-cancelling pattern digs in on loose ground while keeping road hum down.

The Endurance casing folds to a clincher bead and runs tubeless compatible up to 55 psi. It measures 56mm on a 21mm internal rim and 57mm on a 23mm rim, in dark tan.
