Here I have a set of 20" Alloys and tires from a 2006 Jaguar XJ 350.
They are in good condition but have had some curbing, as shown in photos. 
All the tires are good and are 255/35ZR 20.
One of the wheels has been professionally welded. It holds pressure fine and has no balancing issues.
Collection is preferred although quite happy to post if the winning bidder organises and pays for it.
