Im looking to get some new tires on my truck because i am about due. I put just under 50k on my Cooper stt discoverer m/t and was pretty happy with them. I do a lot of towing and freeway driving in my truck. I would like to go to a tire with a little smoother ride and a little quieter ride. I am going to also drop down to a 285/65/18. I like the Nitto Terra Graps but have heard they dont last. Any suggestions on a good A/T tire that will last and ride comfortably down the road? Thanks!
