I purchased a 2005 Cardinal 5th wheel. It still has the original tires. Even thou they look good I know they deteriorate. Should I replace them prior to hitting the road this summer
depending on tire size and weight there will be a lot of very good LT tire options for you. Lots of people like the Michelin XPS Rid and also Bridgestone Duravis R250 - for lighter weight rigs the Firestone Transforce HT, BFgoodrich Commercial T/A2 and Toyo H/T are all highly recommended around here. (cooper, goodyear and yokohama also have options).
