I have purchased many tires from independent Tire Stores.. SOME OF THEM (Check before you buy) When they sell you "Road Hazard" it is, in fact, a "National" Insurance company that is providing coverage.
YOu can go to ANY dealer. Name does not matter. But ANY Dealer who sells that same Road Hazard policy and get a replacement.
That said. Motor home gets Michelin, only tire that fits. under FMCA plan so it's factory covered.
The car goes to Wal*mart for reasons in the opening post.
