If you're only looking for 1 wheel you can usually find them on eBay, not inexpensive but I'm sure cheaper than Polaris. If you're going to run the stock wheels and tires than buying a full set like Mr. C has would be your best bet. You could use 1 for a spare and when your tires are worn out you would have new set of tires then use one of the worn tires for the spare.Is the stock wheel for 2025 Ultimate on the Polaris accessories site. Does anyone know the part number please
