Yep. that is the size.

 

Then what's the non sport sizes for 03/04? For 05 models, 215/55/17 are the non-sports.

 

I think when they first came out the non sport was 16" and then in 2004 the non sport was a 6-spoke 7.0 x 17-inch alloy wheel.

 

From the 2003 G35 catalog [paraphrased]...

2003 "Standard" (Base Model) -
5-spoke, 6.5x16" aluminum alloy rims
205/65R16 V-rated all-season performance tires

2003 "Optional" (Leather & Winter Package w-Sport Tuned Suspension) -
6-spoke, 7.0x17" aluminum alloy rims
215/55R17 V-rated all-season performance tires

2003 "Optional" (w-Sport Tuned Suspension) -
5-spoke, 7.0x17" aluminum alloy rims
215/55R17 W-rated summer performance tires

 

Wow...so confusing. So when you see a G with 5 spoke, it can be 03/04 non-sport/sport.

 

I have the 2003 leather model with sunroof, non-premium, non-sport. It came with 215 55 R17s on six spoke wheels. I have since upgraded to the sport-tuned suspension, 235 50 ZR17 tires and Stillen sway bars. She handles great! The 6spoke wheels are actually the lightest wheels on a G.

 

Cato,

So you went back to Infiniti to do the sport-tuned? If you did, I am curious how much they charge you.
