Description
- New Mutant X-MT
- Maximum Traction Mud Tire
- Conquer any challenge with the New Mutant X-MT, the most aggressive tire in the lineup. Its dynamic tread pattern and high void ratio effortlessly evacuate mud, dirt, snow, sand, and rocks for constant traction.
- Deep tread blocks and massive side lugs deliver superior grip, puncture resistance, and confidence on harsh terrain. On pavement, the variable three-pitch tread pattern minimizes noise and vibration. Built for rock crawling, mud bogs, and heavy loads, the X-MT is durable and reliable.
- Key Features:
- ● High void-to-lug ratio for extreme off-road conditions: This design keeps the tread clear and provides superior traction in mud, snow, sand, and rocky terrain.
- ● Staggered shoulder lugs: These lugs enhance grip and biting edge on rocky terrain.
- ● Deep tread depth: This provides better off-road capability, hydroplaning resistance, and a longer tread life.
- ● Deep siping in the tread blocks: This improves grip and braking performance in winter and on wet surfaces.
- ● Mud and stone ejectors: These features help to shed mud and prevent stones from drilling into the tire.
- ● Advanced "X" tread pattern: This design maximizes traction in any off-road terrain.
- ● Aggressive "X-TREME SPIKE" X-MT dual sidewall design: This design offers added off-road traction, sidewall armor, and a unique aesthetic.

+About Electric Vehicle Tyres
About EV Tyres
Electric vehicles often require tyres that can handle greater weight due to their heavy battery packs. They also benefit from tyres designed to withstand the increased torque and unique performance demands of EVs.
We stock both dedicated EV tyres and higher load-rated tyres that can be suitable for electric vehicles.
Important Information
Always check your vehicle's required load index before purchasing. Higher load-rated tyres (XL) offer enhanced weight capacity and durability suitable for many EVs.
If unsure about suitability for your specific EV, contact us and we'll help you find the right tyre.
Available Options (Sorted by Size Match)
Electric Vehicle Tyres
Tyres specifically designed for electric vehicles with optimised rolling resistance and noise reduction.
Higher Load-Rated Options

This tyre carries no EU wet grip grade, so we will not put a score on it. The full driving safety report can still score your own vehicle and tread depth for your town.
