Be advised there is a configuration file which must be updated for the system software to properly perform certain performance calculations with replaced wheels. This file can only be installed at the Jaguar dealership. They only have such files for the 18", 20", and 22" wheels which are delivered with the vehicle. I downgraded from 22" to 20" wheels in order to have all-season high-mileage tires. My configuration file was updated BUT it had no effect on what the instrument panel shows for the recommended tire pressures. The dealer was not able to change the recommended values shown in parenthesis on those screens. The black driver side door label shows the recommended pressures for these three wheel sizes along with the detailed label for the wheels delivered with the car.
My 22" wheels are available should anyone want to upgrade. They only have 3300 miles of use and are in perfect condition. Reply to this thread if interested. Great deal and they are professionally packed and ready for immediate shipment anywhere in the US. Save lots of $$$ and give them a good home. The Perilli summers tires have 6500 miles of remaining tread life.
