Help with fitment? New Z owner 😀

Godsgotyoubro

New MY09 370z owner, not too familiar with fitment of these cars yet! 😬
The rims i bought are 20x10.5 +15 rear and 20x10.5 +25 front. Im fairly set on 255/35 for the front but as far as the rear should I go with a 305/30 without any spacers? Or should I add a spacer and run a smaller tire?
The smaller the tire the more affordable so I'm really wondering what size tire with what size spacer you all recommend. Thanks in advance!

Same width wheels are usually 20-25mm different in offset's.....rear's are sunk compared to the aggressive front's.....A 255/35,305/30 tire combo,is better suited for 9/11" stagger wheel's.
Gonna be stretched up front & bulging out back.
What are your camber spec's? lowered? etc...?

I'm all stock at the moment but plan on lowering soon. So aside from the 305/30 idea, say I wanted to put a 15mm or so spacer on with minimal camber, what size tire would fit without too much fender rolling?

Not dodging you;got called in for work today.
Look up some thread's on Z's that run rear Nismo wheel's on all 4 corner's....19x10.5+23's,,,you may be able to get 275/35's on the front,
also it would never hurt to test-fit some good used tires up front to see...I have 285/35/19's up front on 19x10's with stock suspension/camber,no rubbing scraping...but your wheel lip's are 0.75" further out, heck you may be fine,,,i'll stick a front wheel pic up.

Wow that's perfectly flush and meaty at the same time! I'm wanting to do like a 285/30 rear with a 15mm spacer possibly but that may look silly without being lowered =( maybe I should do a 265/35 or 275/35 rear and throw some 15mm spacers on so it won't look too weird until I lower it? I've had so many lowered cars I never knew it would be so hard to decide on tire fitment lol

The spacer's for your rear,would just bring the wheel out to evenly match the front-you won't necessarily know how much; till you get your front tires in check.
Sizes close to oem would be 275,285/35(F/R) or 285,295/35's.....with car being heavier in front-it would make a more even fitment on wheel (F to R) with just a 10mm difference in section width & same profile/series of tire...+ would give you a slight rake.
If those are too tall to clear the front....could go 275,285/30's....285,295/30's or even 295,305/30's.
It's whatever float's your boat....
1st thing-get the front sized & fitted first,before purchasing a complete set...other's may chime in & help you with this.
