Standard on TRX-4M High Trail Edition trucks, Mickey Thompson Baja Pro XS 2.4x1.0″ tires are taller than standard TRX-4M tires for more ground clearance and an aggressive stance. Tires fit standard 1″ TRX-4M wheels and 1″ beadlock wheels. For extra control on the trail, try 9874 firm or 9875 soft foam inserts. Long Arm Lift Kit recommended to prevent rubbing.
