Mickey Thompson Baja Boss M/T — 40X13.50R17LT

Forty inches on a 17" wheel. This isn't a tire you stumble into — it's the result of a build plan. The 40X13.50R17LT is for dedicated trail rigs where maximum height, massive sidewall flex, and the ability to crawl over anything matter more than highway manners. Load Range C keeps the sidewall compliant at low pressures, which is exactly where this tire does its best work.

What makes it stand out:

• Asymmetric tread pattern digs hard in mud while keeping road noise and handling in check for the drive home
• Extra-large four-pitch Extreme Sidebiters® provide unmatched sidewall traction and protection on rocks and off-camber terrain
• PowerPly™ XD three-ply construction resists punctures and keeps the sidewall stable under load
• Stone ejector ribs prevent gravel from packing into tread grooves — critical for mixed terrain use
• T4 silica-reinforced compound delivers wet grip, cut and chip resistance, and lasting tread life
• Load Range C — softer sidewall construction designed for maximum flex at low airing pressures
