14 to 15 inch spare combo
I use a 17" spare from a '07/08 Infiniti G35. Fits in the well, it's not perfectly flush with the floor but it's pretty close. It clears my 13" rotors in the front too, which is why I had to use a 17" spare. I think it has a 145/80/17 on it (~26" tall). All I did was a little dremel work on the hub bore, it was a couple mm's too small. Nothing major though, especially for a spare.
