Have been very happy with Cooper tires. Had the Cooper Discoverer ST's for around 3 years. Just replaced them with the ST maxx. After 3 years i still had around 50% tread but due to driving them with mud all over the wheels they finally started cupping bad enough it was shaking me to death.

The ST maxx are very quiet and very aggressive off road. Coopers have been by far the best of the many a/t and m/t tires ive tried.
