Not directly related however, I had a spare set of F-Type Propeller Wheels; Front: 245/40 ZR19 (94Y) Rear: 275/35 ZR19 (96Y). Advertised them for sale and they were bought by a fellow Jaguar enthusiast who wanted to fit them to his 2008 4.2 XK Convertible (X150). He had checked with Jaguar and they confirmed the stud patterns are the same. After purchasing the wheels I received a photograph of the XK fitted with the Propeller Wheels.
It not just about the wheel diameter, width and stud pattern. Getting the ET value right is vitally important to avoid handling problems and in the worst case tyres rubbing on the inside of the guards.
Offset is stamped on a wheel as an ET value, which refers to the German phrase Einpress Tiefe. ET indicates the distance between the mounting surface and the geometric centre of the wheel (the symmetry axle), usually expressed in millimetres. When the ET value decreases, the alloy wheels will protrude further out.
