Mickey Thompson Baja Boss M/T 42x13.50R17LT

Mickey Thompson Baja Boss M/T 42x13.50R17LT - Extreme Mud Terrain Tire

Dominate the most extreme off-road terrain with Mickey Thompson's game-changing Baja Boss M/T in the highly anticipated 42x13.50R17LT size. This ultra-premium extreme mud terrain tire combines aggressive, in-your-face styling with serious trail performance in a package engineered specifically for the incredibly popular 17x9-inch wheel fitment.

First-of-Its-Kind 42-Inch on 17-Inch Wheel

Mickey Thompson made history with this tire size—the first 42-inch diameter tire designed and approved for 17-inch wheels. The strategic 42-inch diameter offers enhanced under-axle clearance while the 13.50-inch width provides a narrower track width compared to traditional 14.50 or 15.50 wide tires, making it ideal for maneuvering through tight rock gardens, narrow trail sections, and technical terrain.

King of the Hammers Proven

This isn't just marketing hype—the Baja Boss M/T is the winner of the 2023 King of the Hammers Every Man Challenge, one of the most brutal off-road races on the planet. When a tire can survive the rocks, sand, and punishment of KOH and come out victorious, you know it's built different.

PowerPly XD 3-Ply Sidewall Construction

What sets the Baja Boss M/T apart from every other mud terrain is Mickey Thompson's revolutionary PowerPly XD construction. This advanced 3-ply sidewall design features a 50% heavier denier third ply than the original PowerPly—setting a new industry standard for off-road tire construction. The angled third ply provides:

• Exceptional puncture resistance against sharp rocks
• Improved handling and steering response
• Greater sidewall stability under load
• Enhanced durability in the most hostile environments

Massive Sidewall Height for Extreme Flex

With a towering sidewall height on the 17-inch wheel, this tire delivers exceptional flexibility and grip when aired down for off-road scenarios. Whether you're rock crawling at 8 PSI or navigating sand dunes at 12 PSI, the substantial sidewall flexes and conforms to terrain for maximum traction.

Next-Generation SideBiters

The Baja Boss M/T features Mickey Thompson's most aggressive SideBiters ever—50% larger than any previous Mickey Thompson radial. These extended shoulder lugs deliver additional biting edges for superior traction in mud, rocks, and loose terrain while providing extra sidewall protection against trail damage.

Asymmetric Tread Pattern - The Best of Both Worlds

Unlike symmetrical mud terrains that sacrifice on-road manners for off-road capability, the Baja Boss M/T uses an asymmetric tread pattern that provides:

• Reduced road noise compared to traditional mud terrains
• Improved on-road handling and on-center feel
• Decreased side-slip during highway driving
• Aggressive looks without the aggressive drone

The deep, wide voids between tread blocks ensure maximum mud evacuation and self-cleaning performance, while stone ejector ribs prevent gravel from wedging into tread grooves.

Silica-Reinforced Compound

Mickey Thompson's advanced silica-reinforced compound delivers better tread wear, improved wet handling and braking, enhanced cut and chip resistance, and superior durability. This means your investment lasts longer—both on and off the pavement.

Load Range C (6-Ply Rated)

The 42x13.50R17LT Baja Boss M/T is Load Range C with a 6-ply rating and 126 load index, providing a maximum load capacity of 3,860 lbs per tire at 50 PSI. Perfect for lifted trucks, Jeeps, and SUVs running extreme sizes without the harsh ride of Load Range E tires.

Fits 17x9 Wheels - Perfect for Modern Builds

Engineered specifically for 17x9-inch wheels (the most popular fitment in the off-road world), this tire eliminates the need to source hard-to-find 20-inch beadlock wheels just to run 42-inch tires. Keep your 17-inch beadlocks and upgrade to 42s.

On-Road Manners You Can Live With

Despite its extreme off-road capability, the Baja Boss M/T doesn't punish you on the street. The asymmetric tread design and advanced construction deliver surprisingly quiet highway performance and predictable handling—making this tire livable as a daily driver.

Mickey Thompson Heritage

Since 1963, Mickey Thompson has been the leader in high-performance off-road tires. The Baja Boss M/T represents decades of racing experience, innovative engineering, and a relentless commitment to building the best performance tires in the world.
