I've had my 2012 2.2L. XF for a couple of months (bought second hand) What's bothering me is there's no spare wheel, just a compressor and a bottle of "jollop". Is there anybody out there who has successfully converted their boot to take a full size wheel. Tyre size is 235/55 R17. I feel the need to have a spare wheel but not a space saver. Any help/suggestions would be greatly appreciated.
