I just put a set of Goodyear Wrangler Adventure's 265/60/18 with Kevlar sidewalls, on our V8 Nissan Pathfinder. They are also made in LT load range E, and have two layers of Kevlar, and have earned the "Snowflake" symbol for severe weather. This is a new tire from Goodyear, and even though it's an AT tire it rides as smooth, or smoother than a lot of highway tires.
My opinion, it's a better tire for a Class B than the Michelins, and cost slightly less.
