Wondering if anyone knows what the full size spare uses for a rim/wheel?
Looking for a set of steel wheels for my snow tires and can't seem to find any that are appropriate, and looking at the spare there aren't any real brand markings on it.

You could go onto rockauto and see if they carry a steel wheel. Or, you could go to a junkyard and see if you can pick up a full set of rims from a wrecked Cherokee. Don't forget, you will need tire pressure sensors, I don't know what warnings would go off if you don't have them.

Brand is irrelevant. You need to determine the bolt pattern, diameter, width, bore and offset. Also if you're going for now tires, you might actually want a different size depending on availability of the tires you want in that size. For example on my Equinox, I went with 16" rims instead of matching the oem 17" rims because the snow tire selection was much better and the tires were $40 cheaper each.

I still curse Chrysler for swiching to an oddball 5x110mm bolt pattern, that doesn't even match the 5x127 (5") on the Grands and Wranglers.

Unless Im mistaken, anything less than 17 on this year range of jeep is too small. Unless its like the compass or another smaller model.

The Trailhawk definitely uses the stock Trailhawk tire (245/65R17), and I believe it's a Firestone, although they later switched to Falken Wildpeaks. It's an OWL (Outline White-Lettered), Kevlar-coated all-terrain tire, and it WILL fit in the spare tire well, as most Jeeps (maybe other than the new Compass, and of course the Wrangler/Wrangler Unlimited, which both have it mounted outside on the tailgate) have a spare tire well deep enough to fit one. I think some Trailhawks use a black steel wheel as the fullsize spare (17" size), or the stock Trailhawk alloy wheel. Of course, most Cherokees feature either the Tire FitKit (inflator pump and tire sealant), or a 17" or 18" donut with black steel wheel. The Trailer Tow Group may also give you a fullsize spare tire and black steel fullsize wheel, but not sure on that. I work for a used car dealer, and the last Cherokee KL we had in was an Overland, and it had the donut. Hope this helps.

You need a steel wheel the same size as the factory wheel. So if the factory wheels are 15 x 7 - thats what you need. You have to keep the same profile as your stock set up. What's wrong with the donut?

You didn't read my whole post. I need a set of rims to put a set of snow tires on, the donut is fine lol.

I was answering the OP not you. He/she is looking for an extra wheel.
