Yes, the Wrangler HT tires do and have given problems. On my 97 Hitchhiker II 5er which was equipped with LT215/75R16 Goodyear Wrangler HTs, I had one blow out and another throw a tread. The tire that threw the tread still had 80 PSI in it. The trailer has been weighed and the tires weren't overloaded and I meticously maintain 80 PSI pressure. Both times they did a number on the plastic fender trim. Goodyear warranted the tires but wouldn't pay for the repairs(no past history of problems with this tire--LT235s yes, but LT215s no).
I took care of the problem--bought a set of Michelin XPS and no more tire problems. I have had Goodyear Wranglers(no HTs) on my last 3 Dodges from the factory and they gave 0 problems and got very good mileage out of them.
