Only experience I've had was on a 1994 Chev Blazer when we had tread separation on a BFG in the Grand Canyon National Park on a Sunday in 1999. The spare was good, but we needed to get down the road and did not want to head out into the wilds with no spare so bought the ONLY tire in our size at the Native American-run service station in the Park.
That tire was a Hankook. It lasted 4 years and 80000 miles. with no problems... .....
Tried to find out if another tire company actually owns Hankook and just markets under that name, but nothign to report there... .
