The Baja Boss M/T is Mickey Thompson's premium mud terrain radial, built on Powerply XD 3-ply sidewall construction that adds heavier denier cord to the angled third ply for puncture resistance and quicker steering response. An asymmetric tread pattern and extra large Sidebiters deliver off road bite while holding highway noise down, and the T4 silica compound is tuned for wet braking, cut and chip resistance and treadlife. In 44X13.50R20LT this flotation size measures 43.8 in overall diameter and 13.8 in section width, carries 3,970 lbs at 35 psi on an 11 in measured rim, and runs 22/32 in of tread depth. Stone ejector ribs keep gravel out of the tread grooves.
