I think we used the Lt tires on the 12000 up armored suburbans in Iraq. They were ok eve with the big run-flat plastic pieces in them. They held up good in those conditions except when the teams drove over crap they shouldnt have anyway.
If you get them let me know how they ride, I'm looking at getting something like that for my wife's jeep. She's got procomp 35x12.5x15 now that are practically brand new, but I don't want to waste them on the road.
