Correct tyre size for XK8 with 17 wheels?

Hi - can anyone tell me the definitive answer for the correct tyre size for a 2002 model year Jaguar XK8 with ‘Lamina’ 17 wheels?

Go to the tire rack and use their search feature.

Don’t know, but on my 1997 XK8 with 17 inch wheels it is something like a 50 series tire.
