SpaceSaver 20" spare.

Thanks everyone but although 20" are the tyres/wheels not so wide used just a get me home??

The point is that you still need to take the original wheel and tyre home, unless you hide it and go back for it
Reality is after 15 years of 2 seater sports cars and dozens of sports car club runs with big groups the times when you are alone so have a spare passenger seat and the tyre is such a wreck that the inflation kit and gunk won't help is probably near zero.

First 5 years of a Z4 I carried a skinny spare. second 5 years it remained in the garage until I sold the car
Stats I saw is a flat once every 90k is the average these days. Of course that said I'll have a puncture tomorrow...

In my experience with Jaguars, I usually get a puncture within the first few days of ownership, usually a screw in the tyre. Not saying my experience is typical, but ... And I've had no such issues with the F-Type so far!
