July 16, 2011 - Can you fit a 225/45-15 tire in the trunk of a Miata? Yes, with the help of a big enough hammer. While I am allowed to carry a space-saver (and I might), I realized that if we did have to change a tire I'd have no place to put it. Since the trunklid is held on by pins, leaving the trunk partly open wasn't really an option. So I stopped for hammer time. tags: spare |
