i'm not too terribly much of a rock guy, i just like doing trails and playing in the dirt mostly. i'm probably overly worried, hell, i've never even aired down...
ya your for sure overly worried if you don't ever air down, 7's are to narrow i say 8's i just sold a set of 34x10.5x15 LTB'S and they worked great i only broke one bead, but it was becaues i was running 6 pounds. i don't think you can air LTBs anyone lower then 10. anyway they were good tires mounted on 15/8 wheels they just weren't big enough, i looking at 38's or possible 39.5 iroks!
