Tragically my Corolla has a piddly little spare tire and no room to fit a full size tire.
Have you beat Izzy, my car that has a spare is a Mazda Miata. Little car, itty bitty spare. It doesn't have the smallest trunk that i have ever seen but it ranks right up there. The hardship of driving cool cars is very little trunk space.
i've got a late model mid-sized car. it has lots of trunk space. it also has a lot of spare tire well storage space under the trunk space.
it could hold either a full size or doughnut sized spare tire, but alas, it comes with neither. it has a 'system' that is supposed to re-inflate the tire while pumping in a sealant.
next week i'm buying a spare.
