We have a 2002 Rialta, and after taking with Winnebago, all major tire suppliers, and a few Rialta repair shops, can't find tires that fit and are rated for the weight--any suggestions would be greatly appreciated.
Any E rated tire in the size of your tires will work. Best to have the same size tire all-around instead of the smaller tire in the front. Former owner of a 2004 Rialta. I have lots of information about the Rialta if you want to email me. Join the Rialta NOTOWBAGO group for lots of info. https://groups.io/g/Rialta
