Hi guys, looking to buy some new wheels for the Z. came across this in the australian forum where i am currently based. I need some help whether the rim sizes and also if the tire sizes are a great fit to an 03 Z. Thanks in advance. The details are as follows:
Front: 18", 8.5 width,
Rear: 18", 9.5 width,
They come with exxy Michelin Pilot Sport PS2 tires (high end UHP stuff).
Front: 245/40 or 45/18, a few mm off markers
Rear: 275/45/18, a mm or so off markers

Not a "excellent" fitment. Most people would rather have 9½/10½" and would prefer them on 19".

The tires could be a problem at 245/40 275/45, if you have TCS/VDC on your model. The preferred size is 245/40 275/40 for 18" wheels.

You can compare your current wheels to the new wheels. How about you decide what is and what is not "excellent."

Depends on their offset. With a good offset, 8.5/9.5 can look quite good.
Front: 245/40 or 45/18, a few mm off markers
Rear: 275/45/18, a mm or so off markers
Better check those tire sizes, as those would be HUGE sidewalls with the 45 aspect ratio.
