...i just got the new off-road adventures from 4wheelparts in the mail (jan, 08 issue)...besides the canfield '07 truck and jeepfest with tons of pics and with all the new goodies coming out, they have a pretty good article on their new pro comp Xtreme m/t (XM/T)crossover tire...for blacktop, sand, rock, and mud...;)
...they took this tire on a 12,000 mile trip including places like moab and san filipe in baja...if you are looking for info on this tire, it is pretty much all there including disection's of the tire and info on the sipping, compound, etc, with comparison to how it is so much better than the pro comp Xterrain's...:thumbsup:
heres the link...;) http://oramagazine.com/pastIssues/0108-issue/index.asp?article=rubber
