The Mickey Thompson BOSS 42X13.5R17 126p is a mud-terrain (M/T) tire.
Off-road drivers who push hard through mud, rock, and loose terrain need a tire that bites in without quitting on the highway home. The Mickey Thompson Baja Boss in 42x13.50-17 is a mud-terrain option built for confident, real-world performance.
With a load index of 126, it supports the payload demands of full-size trucks and SUVs while maintaining a P-speed rating for everyday highway use.
Aggressive tread blocks dig into mud, sand, and rock while reinforced sidewalls shrug off cuts and impacts. Commonly chosen by owners running aggressive off-road work, weekend trail runs, and job-site duty, the Baja Boss bridges the gap between capability and comfort.
A maximum load capacity of 3748 lbs make it suitable for full-size trucks and SUVs carrying gear, equipment, or cargo without frequent pressure adjustments.
