Email and call Bridgestone. make sure you have all you paperwork and can prove you bought the tire as-new and they were 2 years old. Hopefully Bridgestone wants to know who is selling their tires for new, way out of date. The RV dealer may have not even looked either, but the tire dealer knows and that is a no no if they are Bridgstone dealer. Talk to Bridgstone professionally, not much emotion, let them know you will be dealling with a safety issues soon and ask for their help. You probably will not get all your money back but I bet they will help you out on a new set of tires. They want to keep customers happy and they do not want to make the news for having places old tires on a 40k lbs vehicle.
My 2 cents
