just got some new skins, 285/70-17 E, so far so good, nice ride. already had it thru the ditch and mud to pull a ladys van out, did not miss a beat. running 70 up front and 60 in the rear, after two wks i will see how they wear and adjust from there, will keep yea posted. i know some people have had bad expericenes with wear, but had a few freinds with ferds and they seem to get good wear from them.
