Hey guys, I'm really have lack of knowledge on wheels. I need some help and advise on what is the correct wheel size and offset, if I wanna go with either 18 or 19 non stagger setup. Thanks!

So far stape width is 9" +32-35 fronts and 10.5" +45 rears!

Couple them with 245-255 front and 275-285 rear tires!

For 19s the side walls of the tires are 40 front and 35 rear while 18s, by logic, should be 45 front and 40 rears!

Hope that helps!

So by thoery if I don't wanna stag them I can just have 19x9 255/40/19 setup or 18x9 255/45/18 setup for both front and back correct?

Yes but you would have to consider the offset on the back though! Maybe just follow the staggered set up done by Platinumv37 then just increase the sidewall accordingly

That might be sunk though! I think with those offsets you can even run 255/40

Ohhh, forgot to mention, also check out the new SSR GTV series! They should be pretty cheap right now! I think they have an introductory pricing!

@gbert15: will all these recommendations be the same for AWD models? How about specs for 19" with 8.5" width (preferably all four the same)?
Yea should be the same but for AWD it cant be staggered right?

19x8.5 should equate to an offset of +26 i think! Basically, from what I learned in the past few days, for every inch u gain or deduct, u add or deduct 12 to your offset to match the offset of the smaller or larger width wheel! So if vossen is recommending a 20x9 +32 what would happen is if u go 8.5 u would have to deduct 6 to the +32 offset since u went down half an inch in wheel width!

Wheels gurus pls feel free to correct me if I am wrong in my assumption! :eek:

Thanks! Wouldn't you have to add (not deduct) offset for narrower wheels though? :confused: I don't know enough about this to say for sure...
Oh nah! Because the lower the number of the offset, the more u stick out! Like for me I used to run a +18 on a 20x10.5 rim on the back of my ssr sp1s for my previous G35! That was fine with 275/30/20 tires but once I went for stretched 255/35/20 tires and wanted my wheels to poke out of the fender, I had to put on 15mm spacers and that made and effective +3 offset!
