I just had duratracs put on my 08. Had them before, tried the KO2’s in between, which I was not impressed with tread life. Tire guy screwed up and put D rated tracs on so I’ve been on them over weekend. Will get E rated put on this week.
If you don't mind - please post your driving impressions of the D vs the E rated tires since you will have them on your truck back to back. You went with 265/65/18 I'm guessing.
