What Makes the Scorpion XC R the Right Rear XC Tire?

The Pirelli Scorpion XC R is built as a dedicated rear tire for XC and marathon racing, combining a medium-profile tread design with added traction and durability to handle the specific demands of the rear position. Unlike a symmetric tire, the XC R is optimized for where the load is highest and braking and drive forces are greatest. The SmartGRIP Compound delivers long-lasting grip in wet and dry conditions with increased resistance to tearing, so the tire maintains its edge through full race distances without losing the performance you started with.

A multi-ply 120tpi Nylon casing keeps the XC R light and fast-rolling while the ProWALL sidewall reinforcement protects against the lateral cuts and sharp debris a rear tire regularly encounters on aggressive XC terrain. TLR tubeless-ready technology makes mounting straightforward and bead retention consistent at the lower pressures that XC tubeless setups demand for optimal traction. Available in 29 x 2.2, the XC R pairs naturally with a Scorpion XC M up front for a complete, position-matched race setup.
