I meant to include this photo in my earlier post, which shows all the numbers related to the space saver spare of a post-2012 4x4 model… tyre size, wheel size and offset
I know this was resolved, but, having got a puncture (in a thunderstorm of course) on Monday, here’s a photo that shows the full size 4x4 wheel doesn’t fit the boot, and another that shows how comical the space saver looks on the car.
