my ssrs were great tires on and off road, only reason I don't still run them is the fast wear. mine were in 33s though. thornbirds were terrible, sxs good and boggers surprisingly decent. ive always had a hd3/4 or 1-ton so the weight over a 1/2 ton probably accelerated wear some. my dad got 60k plus on 285 bfg at on his hd3/4 though.
these were on a 3/4 ton ford diesel.
