I've had two sets of these tires in a span of about 3-4 yrs both going roughly 60k-70k miles. These tires reliability and the brand and models sustainability over the years is perfect. They obiously found a design and rubber compound that work great and have not changed it. In this case that is a good thing! Originally when I went to buy these tires the salesperson tried to steer me away from them saying that they would be noisey on the highway. I am very happy I did not take their advice. I just love these tires on trucks. I drive luxury cars also so I know what a good smooth quiet ride is supposed to be. And these tires are tough off the road and nice on the road as well. Over all super tire.
