I own a 2001 Silverado and replaced the factory Goodyear wrangler ST at 32,000 miles with Michelin XC LT4 tires. I now have 115,000 miles on the truck.
That means I've driven 83,000 miles on these tires and have at least another 25,000 miles worth of tread left. I'm going to get another set today for my wife's truck. I've got nothing but good to say about the tread life, traction, noise and value. I'd give it a 5 star rating.
