The difference between a true offroad tire and a dual purpose tire is the
plies and design of the sidewall. The MT types usually have a reinforced
sidewall to resist all but artillery getting through. Surface cuts and
abrasions are typically handled by most any tire. Its the lurking lance or
super sharp rock that the offroad tires are designed to resist. Any tire
driven with bulging sidewalls will pick up cuts, its how deep a cut holes it
that is important.
Personally, I've driven a tree branch through and cut the sidewalls on a
rock badly enough to lose air pressure. Both of these punctures were with
old style bias ply, M&S tires which were supposed to have way stout
sidewalls. I've been driving on a non off road sidewalled, MT tred, radial
tire for the last 5 years without any problems, however. They look like
sh*t with all the nicks and bruises but haven't been holed despite my best
efforts.
Off to pick up my 235/85/16 TracEdges from Costco. $112 each including
freight to Kona. Should be cheaper in the real world. Too bad Costco can't
get 7.50/16's.
