Over and above a standard 3.0d, the Aussie delivered 3.0d Sport came with sports suspension, staggered 19s (225/50 front and 285/45 rear), door handles in body colour, sports steering wheel, sports seats, electric seat adjustment with driver memory, anthracite roof lining and auto-dipping rear view mirror.

Just to complicate things, most of these options could be ordered individually. The sat-nav and TV on your X would have been options.

The 235/65s are the standard tyre size for the 17s. Regardless of what wheels E53s came with (17s, 18s, 19s or 20s), the spare was always a 235/65R17 as it is the only size that the wheel-well will accommodate properly. That's why I mentioned that particular advantage of the 17s ... your spare is a full match for the road wheels.
