I'm not sure if the X-Type wheels will fit or not, but my guess would be no. I bought a set of "Dimple" style X300 wheels with Pirelli tires for $50 each on Craigslist and a matching full-size spare from the junkyard for only a little bit more. It's my understanding that most X300 wheels will fit on XJ40s, assuming that the tire aren't too big; it's a pretty common upgrade. Hope this helps!
