We have a Sundance 5th wheel bunkhouse with 1 slide. It will be needing tires this spring and I have been told to stay away from the Chinese tires, only get tires made in the USA. It weights about 8000lbs loaded and has 225 75R15 tires on it now. Anyone have a suggestion on which are the best tires to go with. I know there are a lot of different brands out there to choose from. I have been told to go with the 10ply tires, they hold up best. Thank you for your time.
