I ran these 37 inch tires on my 2005 LJ for a little less than a year. 4 of the tires have about 1200 miles on them, the other is a spare that was a takeoff and has less than 25 miles on it. They've never been off-road, no plugs, no patches. There there's nothing wrong with them, in fact, they're in almost brand new condition. I took them off to go back to 35 inch tires, my old school 4.0 L straight six struggled a little bit to accelerate up hills on the freeway. They are currently mounted to 17 inch steel wheels that are also in pretty good shape. The lug pattern is 5 x 4.5. Check my other ads, I am selling some icon 17" wheel wheels as well.
