I have a shot to get some tires and rims pretty cheap but I don’t want to waste money if there could be some backspacing issues. They appear to stock tires on stock Honda Rancher rims for around $60. They are 25x10x11 and 25x8x11. I know the OE 1988 setup was not different sizes so that has caused me some concern.
I am going to continue to investigate back spacing here in the forums.
