The Mickey Thompson Baja Boss M/T is a mud-terrain (M/T), all-season, all-weather tire. E construction.
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 M/T in LT285/55-20 is a mud-terrain option built for confident, real-world performance.
With a load index of 122 and load range e, it supports the payload demands of full-size trucks and SUVs while maintaining a Q-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 M/T bridges the gap between capability and comfort.
Load range e and a maximum load capacity of 3305 lbs lbs make it suitable for full-size trucks and SUVs carrying gear, equipment, or cargo without frequent pressure adjustments.
