I run Kelly Safari Trex. 285/70/17s. I also have Kelly's on the minivan.
I am not a fan of Coopers. My dad had two blowouts going down the highway within 2 weeks, on about 80% tread. Now both his fenders, running boards, and headlights needed replaced. A person in my Plymouth club also bought Coopers and within a week of buying them had a blowout. When I bought my truck it also had Coopers.
