I've lookd through all the old posts re spare tire for 4.2l XKR with 20" Cremona and Alcon brakes. Is the part number "9W83-1007-RA" shown for XF 19" spares on EBAY an asembly number that includes the "C2P12621" wheel that is speced in the old threads? Or is it an aftermarket cross? I found one site that mentioned it as "Interchange Part Number":

One of the EBay Pics shows 9W83-1007-RA stamped on the wheel.

A couple of black ones amongst all the red ones. Will they fit my 2008 Portfolio XR with a spacer for the rear?

 

All I can tell you is what worked for me, way back in 2012. A lot has changed since then, and you'll have to figure out if other compact spare wheels will work. Sorry I can't be any more helpful. See: Spare Wheel/Tire for XKR with Alcon Brakes
​​​​Good luck!

 

Maybe I should just learn to love my inflator and can-o-goop.

 

Yup - had my XKR since 2016, never had a puncture. The can-o-goop has helped me a couple of times in my Sport Trac driving on logging service roads. I ain't changing a wheel in mud and snow ever!!
