Aight . . . I'm still looking for more opinions on these tires. This summer I am moving up tire sizes to either 37 or 38s, and the 38.5x14.50x15 Thornbird is a burly lookin tire. Their real OD is 37.1 and they have sipes for road traction. I have heard things like they are great in the mud, but not too good in the rocks. Anyone out there with any experience on these treads?
