Not sure what the price is nowadays, but I went to my local dealer to get a set of front rims to match on the back of my machine, they were $140 each. I wouldn't pay more than 75-80 for OEM rims, especially if I had to ship them or drive to pick them up. At that point I'd just go get the ones from the dealer.
Sold my OEM tires for $300 for all 4 right after I got the machine (almost no miles on them, maybe 50 total gravel miles), kept the rims.
Not many people want factory rims, or tires.
