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

 

Moved to proper forum

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.

 

+1 dave knos all my tires are 245 40 and 275 40 ernie

 

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

 

What is excellent fitment?

 

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.
