These tires have seen lots if hwy, gravel, pastures, feed lots, snow, mud, and everything else that agricultural can provide plus pulling our 32' travel trailer around throughout the summer. 56k miles on the tires now and still have 6/32 tread. Very happy! I will replace with the same.
The treadware on this tire was bad. It was supposed to be rated for 70,000 miles. These were expensive tires. The tires were worn out in 34,000 miles, half what they were rated for. I did not tow or carry heavy loads. Then I had to pay 50% more for a set of new tires. With luck these two sets of tires will get me to 70,000 miles at a cost of nearly $400 a tire. I will not be buying Michalin tires ever again.
