I put these tires on my 2007 Silverado LTZ 4wd at 42,000 miles when the factory tires were feathering and wearing terrible. I have rotated every 10,000 miles and try to keep them inflated to 45psi. The only challenge in that when I get the oil changed, the service guys always set them back to 35psi as this is the recommended inflation from Chevrolet. I now have 139,xxx on the truck and while there is still tread left, the traction on takeoff is suffering. They have worn evenly without any noticeable cupping, feathering, or bulging. I have driven probably 80% highway for most of the time until about the last 10,000 miles recently have been mostly city driving. I have done light offroading and never had a problem. I did experience difficulty when there was about 10 inches of snow on the ground a few winters ago. I was lazt and didn't want to shovel the driveway, couldn't get any traction. I didn't blame the tire though. I have been really pleased with these tires. The best part about it is that I ordered from Tire Rack some time in early 2010. They had a special going on for $125ea and they included free shipping. I only wish I would have bought another set to put in storage until time came to replace. Awesome tire, I would highly recommend.
