We upgraded our wheels and tires! Our Airstream came with 15″ aluminum wheels and Goodyear Marathon tires. A lot of folks love Marathon’s and get very good service from them. If we didn’t read so many Airstream blogs and forums, we probably wouldn’t have made the change, but we do read blogs and forums and that made us somewhat uncomfortable with the Marathon’s. So, here’s a picture of our new 16″ aluminum wheels wearing Michelin LTX M/S2 tires!
