Designed for aggressive rallycross use the Pirelli MT 21 RALLYCROSS R 120/90R18 65R delivers focused off-road traction for competition and intense practice sessions. This tyre sits in the motocross rally segment where fast mud clearance and predictable behaviour under braking are essential. Its profile is tuned for a wide contact patch that balances traction and steering feel on loose surfaces.

The tread features deep, widely spaced knobs and reinforced shoulders to optimise water evacuation and self-cleaning while maintaining cornering stability. Construction uses a reinforced carcass and bead area to support high lateral loads and quick directional changes, offering confident feedback through steering response. The compound formulation preserves grip across variable temperatures and rough terrain, aiding even wear during repeated stages.

For the rider this means improved confidence in braking distance and controlled exits from corners even on soft ground. The robust build increases load capacity and resists damage from rocks and jumps so maintenance intervals can be efficiently managed. Overall the tyre gives a competitive edge with reliable traction in mud and gravel and durable construction suited to demanding rally conditions.
