Anyone using donut spares?

I used to carry a 17" spare from a '07/08 Infiniti G35 before I removed my spare tire well. It fits in the well, clears my DoctorDiff 13" cobra style brake kit in the front too. It has a 145/80/17 on it (~26" tall), which is the tallest tire that will fit in the spare tire well. You won't be able to do anything about fitting a spare for the rear wheels in the well if they're taller than 26". In the front a 27" tall spare may work because it's so narrow, but that will depend on its offset/backspace.

I did a little dremel work on the hub bore on the G35 spare, it was a couple mm's too small for the DoctorDiff hubs which are about the same as the 73+ mopar disks. Nothing major though, especially for a spare. It doesn't sit perfectly even with the trunk floor, the center of the rim sticks up just a little because of the curvature on the spokes.
