I have a simple question, I haven't been able to find a solid answer. What width wheels will fit on an 88 XJ6? I believe the stock width are 7in with approximately 20mm offset. 7.5 width is common on wheels nowadays I'm sure they would fit right?

 

If it has the 20-hole road wheels, the offset is 33 mm. 7" width, 7-1/2" shouldn't be any trouble, but I haven't seen any aftermarket wheels with the offset you'll need. One solution is to look on eBay for other Jaguar XJ or XK series wheels. They have the correct offset and there are plenty of different styles and sizes available. A weird aside: Jaguar XJs from 1968 through at least 2003 use the same wheel bolt pattern as intermediate GM cars (5 on 4-3/4"), and lhe lug nuts are 1/2-20 like Fords used for a hundred or so years. Go figure...
