Just hard to believe that we spend so much money for a rv. When I buy a new unit I quickly look at tires and if Chinese built or any cheap john unit I go find quality and change them out. Ive known of trailers that blew a tire and it cost up to 5000.00 to repair. My Cameo came with Duro. I ask the Colorado dealer if they were any good. Naturally said they were. When I got back to Texas I had Michelin LTs installed. Should have checked rvnet before signing on the dotted line. Check rvnet. Weve had a lot of tire experience among all of us!
