I actually think a 20" wheel could look really sweet on the new sedan, you would have to choose the right wheel though with some lip and no bling-bling chrome. After saying that, for my car a nice 18 would be be all I need.

 

19 inchers look good on a G.

20's look even better but you will have to deal with more cons than pros imo

18 is just way too small

 

Actually, from what I've heard, dub = double dime = 20...

 

Shows how much I know, I thought DUB was a brand!

 

Well I'm in the OF Club and I actually always thought of the 20's as Dubs.
I don't know where I picked that up

 

The sedan is a pretty big car and I think 20's will work fine. I myself prefer 19 but 20's look killer. Get 20 then downplay the style to prevent the ghetto-ish look.

 

I think people are forgetting that it depends on the tires you run on the rim I have had 19" for a year now and for 6 months I used Toyos 245/40/19Zr the ride was not great and that was due to the fact the tires were Z rated I switched to Bridgestones (245/40/19Wr) and I have better handling and ride quality than I had with my factory 18" wheels. You can go with either 19" or 20" staggered or all matching the key to optimizing your ride quality is investing more in your tires.

 

it is...it's also a rim size.

 

OK good, I don't feel like a complete idiot now.

 

You and John105 are both correct. Dub = 20" which is derived from double dime (two tens). 22" would be Dub-Twos, 24" Dub-Fos (or Dub-Fours)...

 

I disagree with most people who are recommending 19s. Usually, I'd go conservative on rims for durability and performance reasons. However, with the G35, Infiniti specified some tires with relatively tall sidewalls stock. 225-55-17s is a really tall tire for a 17" rim and 225-50-18 is a really tall tire for an 18" rim.

Therefore, if you were to go with 19s, especially in a design with a deep dish, your rims will 100% for sure look small and the tires will look fairly thick.

Thanks to the nice beefy sidewall on the stock G35, going with a 20" rim will still get you tires w/ decent sidewall height which = decent ride quality and durability.

You would probably be running 245-35-20 F and 275-30-20 R tires with a 20" set up and that is not too thin of a profile compared to what many others are running on other cars.

If you must get 19s, please heed Infamous425's advice and stay away from the rims with a lip. Get one where the spokes extend to the edge of the rim and it will look OK.

 

Ok, I'm not calling myself a wheel and tire expert by any means, but when I purchased my last set of wheels for my old G35 coupe, I researched tire sizes and offsets and widths and everything else you could possibly imagine and I came out with the combination below in pictures (first combination of widths/tire sizes/offsets on the boards - 19x9.5/10.5 +39 all the way around - 255/35 fronts, 285/35 rears) - after having 19's for over a year on my coupe, I was tired of them because they still weren't "proportionate" in my mind - 20's are perfect on the coupe, and I have no doubt they are the only way to go on the new '07 sedan - I'm the type of person that isn't going to skimp on wheels, so I would be going with a forged multi-piece wheel as it is, so the weight differences are not important to me (if unsprung weight and horsepower were priorities, I'd keep my 400+hp M5!) - forged wheels are going to be able to withstand whatever abuse you want to dish out, and the rubber thickness is so much more on 20's than smaller tires in order to withstand the abuse that a lower profile tire is prone to...

I've already decided to get a set of IForged 20's (please don't start on the "horror" stories - I know hundreds of satisfied customers) custom made in hyper gunmetal (w/ some mesh design) in 20x8.5 front/20x9.5 rear with 245/35 fronts and 275/30 rears - this is the same setup that many E60 M5 owners are running and in fact, most are now going with 21's (new Hartge classics - amazing, but like $6k for just wheels!) and they look perfectly proportionate to me...

Go with 20's unless the roads that you drive daily are horrible - if you do, you will not have to worry about "buyer's remorse" like I went through with my 19's...

 

Well, I guess it all depends on what your idea of small is.

Do the fat lipped 19" OEM rims on a Porche 911 look small? They are not 20 inch wheels. How about the 19" OEM wheels on a new Ferrari? They look good to me.

For example, here's some 19" wheels on a coupe that was posted in the wheels forum and they look good to me.



Not saying the 20's look bad. I honestly can't tell the difference between
19's and 20's in a photo most of the time.

 

Visually for a sedan I would go with 19". the coupe looks good with 20's becuase of the long door and longish looking wheel base. 20's on a sedan look to big and dorky.

 

^^ I agree...I don't know what I was thinking.
