Before we could start playing in the dirt, we dropped the air pressure in our 37x12.50R17 Maxxis Trepador Radials. Since we are running ATX Chamber Pro II beadlocks, we were able to drop the air pressure to a more usable 7 psi in the front and 5 psi in the rear. The clay at Gulches is some of the slickest when it gets wet. Thankfully, the Trepadors didn’t leave us spinning in our tracks. We were amazed at how well they gripped and cleaned out. Look for a more detailed tire and wheel review in a future issue.
