The Porcupine is back. A modern, open, and easily rolling all-mountain tire profile. The placement of the tread knobs is inspired by the appearance of a porcupine: spiky knobs for exceptionally high grip. Tire models with black and white tread rubber are available, just like in the 90s. Various tire sizes and widths are available. Casings in black and skinwall are offered for all tire sizes and widths.
