You don't want truck tires you want RV tires. They are the same size but not made the same way and are not used the same way. Check out the FMCA tire program.. I have never used but have heard nothing but great things from those that have used it. The tires are RV tires and sent to your tire dealer. It is at least worth checking it out. Don't use the RV for any reason other than to get the tires replaced. You should never drive an RV with 10 year old tires.
