The IRC VX-40 rear motorcycle tire is designed for riders who demand dependable traction and precise handling on intermediate to hard-packed terrain. This 120/90-18 tire features a 65M rating and is engineered for motocross tracks, hard-packed trails, and other off-road applications where predictable grip and responsive control are essential. Manufacturer part number T10573 and vendor part number T10573 identify this IRC replacement tire.
Its aggressive tread design uses additional knobs to increase ground contact where traction matters most. Optimized knob spacing helps create a larger contact patch, supporting confident acceleration, cornering, and braking on firm terrain. The tread pattern is tuned specifically for shredding through hard-packed trails and race tracks, making the VX-40 a practical choice for off-road motorcycles requiring a dedicated rear tire.
Feature: Lightweight 2-ply plus breaker-ply casing provides a balance of stability, flexibility, and controlled handling. An improved rubber compound is formulated to balance off-road performance with durability during demanding riding conditions. The IRC VX-40 is intended for compatible motorcycles using a 120/90-18 rear tire and should be selected according to the motorcycle manufacturer’s fitment requirements. This tire is marked NHS, or Not for Highway Service, and is not intended for public-road or highway use.
