No one has mention one crucial bit of information: Jaguar itself warned against fitting wire wheels to the XJ - the car is too heavy and the forces on the wire wheels too great.
I have chromed wires on my Mk 2 but would never have considered fitting them to my XJ cars. And yes, they are a pain to keep clean but when they are clean they look great.

 

I agree with Gregory, the XJ is heavy, at least up front, for even the 72 spoke wire wheels, they will turn into spaghetti marshmallow. Then you need to use Tubes, another hassle.

 

My '94 XJS had beautiful Dayton wire rims when I bought it. They were dated 1993. But while they looked flawless, they were loaded with probably 5X the weights of a normal wheel - front, back, inner, outer. Car was undriveable above 65mph; felt like it would shake apart.

So I swapped them out for Teardrops I scored on eBay for $150 (shipped!}. Drives perfect now. My tire guy said the wires would be impossible to balance. Plus, they weighed over 30lbs.

I won't, in good conscience, try to sell them on eBay for more than $200. Maybe I'll practice my welding skills and make lamps or a coffee table out of them
