Hi Joe
I don't know what style of alloy wheels I have, but if I buy a second hand one as "spare only" use, any style Jaguar wheel will do, tyre will be anything as long as it's compatible with what is on the car now. If you want to go to the cheapest end of the market, Tyre Shopper sells one to fit mine 235/55 R17 103W load rating for £55:42, includes Delivery to a National Tyre Centre of your choice, Fitting, Balancing, Valve, Old Tyre Disposal, Lifetime Guarantee. I'll keep looking for an alloy wheel though.
Regards
Rodney
