The go-to tyre for aggressive riders, the XR4 Team Issue delivers incredible grip and fast-rolling efficiency from an improved tread pattern. An aggressive tread bites into loose, rocky terrain for confident cornering and braking, while a dual-compound rubber squeezes out maximum traction.

  • Aggressive tread for loose and rocky conditions
  • Confident cornering and braking traction
  • Tubeless Ready (TLR) for easy setup and added puncture protection
  • Inner Strength sub-tread protection against punctures
  • 61a/50a dual-compound rubber for grip and durability

Grip when it gets rough

The dual-compound rubber balances cornering bite with rolling speed, and the Inner Strength casing adds lightweight sidewall and sub-tread protection to keep you rolling through demanding terrain. The supple 120 TPI casing delivers great ride feel.

Built for aggressive trail mountain biking on loose, rocky terrain. Available in 27.5in and 29in sizes across multiple widths.
