3,000 miles and I have a 6.2. No doubt the tires spun under power and i could easily kick out the rear, but I always felt under control. The tires were good under normal driving and did a good job when I stomped on the brakes. Take all of this with a grain of salt. This is my first ever truck so I have no idea how other tires would compare to these, so for me, they were a pleasant surprise. My wife drives a Honda Pilot with Conti all seasons and the truck felt better than that. I drove both in the same snow storm. My previous car was an awd Audi with Blizzaks for the winter.
