Tire Description

Make it ready.


Extreme on demand.

The amount of rubber on the road is optimized to provide excellent extreme terrain traction and enhanced driving feel.

Loves to be aggressive.

The aggressive upper deep "side biter" design increases off-road traction, as well as sidewall abrasion resistance.

Get that dirt off your shoulders.

The scallops provide a "mud-scoop" effect for superior off-road traction. Traction edges on the alternating shoulder elements add additional biting edges for improved lateral grip.

Get a grip. And keep it.

The wide grooves between the outer tread blocks allow the MXT to easily clean out, increasing grip for superior traction.

H2 no.

Siping for increased wet traction on the highway also provides extra biting edges for enhanced off-road traction. Even at half-worn, 80% of the MXT's sipes remain functional, providing for more consistent performance throughout the life of the tire.
