Family motorhome had a blow out near Muncie Indiana and the Roadmaster tires were available from the road side service company. The remaining tires were Michelin and my father-in-law wanted them all the same, so I replaced them a few months later when in stock at Saginaw Michigan. I did not notice any ride difference with the Roadmaster by Cooper tires.  Now I need to free up space in my garage and I am selling the tires. I have the receipt for the tires, they are 2 years old. DOT 1CR 0ALU81.
