I have just upgraded the rear tires on my 2000 XK8 and have two bolt on wire wheels for sale. They are for 245/50 R17 tires. I have been running them on the car since I purchased it - they have about 25,000 miles that I know of on them. One may have a very slow leak. Other one appears okay. Both look-like new on the outside. If there is a slow leak it probably could be repaired or a tube could be put in the tire. (I have owned and rebuilt probably 50 XK-120/140s and I'm very surprised that the XK8 is tubeless.) They are located in Dallas, Texas. I'm not sure of the price range or shipping but I am open to offers. I will be happy to send photographs. Contact me on site or through markvman@sbcglobal.net. Thank you.
