The MK1 Punto came with a cheapo limited-use spare wheel, not exactly a space-saver, but uses the same rim as the other 4 wheels, the first thing I did after checking the numbers stamped into the wheel were all the same, was fit a normal tyre, 165/65R13 like the rest, which fits into the spare wheel well no problem, just leaves the tool tray a little proud under the floor covering. Why they can't do the same with the latest cars is best known only to Fiat. After all when you get a flat tyre and put the spare on, you have to put the punctured wheel somewhere while you get it to a tyre shop, if it won't fit where the space saver went, what are you going to do, put it among the back seat passengers maybe ?
