This is what I think I will do. The more I research and the more I measure, the more confused I get. The original manual says the rims are 17.5 X 8.
It's hard for me to know how to measure the exact rim size but mine "could" be that.
Looking at the close proximity of the front tires to the tie rods, I know I need to be careful with the backspace. Looks like most guys are going with a 4" bs, my existing is right at 5", so 4 should be ok. Sheese!
