The TLR is the Tubeless Ready model of the AGILEST range. The "Panaracer Ratio" is in full effect with this tire. ZSG AGILE COMPOUND has been combined with the super supple "Advanced Extra Alpha Cord" to deliver a grippy low rolling resistance supple ride. The bead has been designed with consideration around current rim profiles including hookless beads for ease of installation specifically around mounting and inflating. (For hookless rims, please refer to the compatibility chart of each wheel manufacturer.)
