Heck, ride by the house & check them out... I’m not advertising them for sale/ but you could possibly leave with a couple.

at least a 2 hour drive to the border, lawdy no!

JC would love to hear you’re thoughts on this. Glad to see you still with us BTW.

Rest Recover then run to a dealership and get another Z! ;)

What brand tires are you considering?
As the Michelin’s seem to have a slightly shaved tread.

Michelin PS4. Thanks!

Just from viewing specs from Tire-Rack, the 27.1” will keep your speedometer accurate;
Looking at the section width- you won’t have a bulge/pretty square fitment & being close to a tad on stretched side.
I haven’t seen any of these tire’s in person; so unsure of actual dimensions vs. what The sizes are posted as.
Your wheel lips should definitely be noticeable with these on & ride quality should be 1st class.
Post pics if you get them,,,as everyone has their own preference to tire/wheel fitment.

These aren’t Michelin tire’s on this Z,,,been looking around for a fitment reference of a 295/35 on an 11” wheel.https://uploads.tapatalk-cdn.com/201...213dfc3894.jpghttps://uploads.tapatalk-cdn.com/201...6c41baf7d4.jpg
It looks pretty square on this 350z...the 255 front’s are listed to be on 10’s...they appear to have some stretch.
You’re getting a premium tire w/Michelin.
I hope the specs posted on the PS4’s are more accurate than what is listed on the PSS’s.
As from previous pics I posted-they run a bit wider & in some cases aren’t quite as tall.
But I can contest that a tire will grow in diameter when mounted & inflated. I’ve seen this first hand with some Michelin A/S 3+’s

As most people are probably aware; especially if you perform your on mounting & dismounting of tires...that the overall width of a wheel (edge to edge) is approximately 1” wider than wheel specs....which are measured from bead to bead on wheel.
This can be confusing to some/ as when looking at backspace chart & figuring where outside wheel edge/lips will sit.
And camber plays a huge role in the leaning of top of wheel...I made a chart for a 26.5” wheel; that showed how much lean per degree of camber.(misplaced it)
But my personal preference is to have tires w/tread as wide as overall width of Wheels....or close. Some people shoot for the section width to be the same as overall width...as these 255/295’s will be....but a lighter & narrower tire will be faster on the straights for sure.
It’s all about what the owner prefers & we’re lucky to have huge wheel wells to accommodate everyone’s taste.

Found the camber chart i made & to keep it simple; the top of a 26.5” tire will lean 1/2” per degree of camber...this is the determining factor when spec’ing out wheels & why sometimes it’s best to setup suspension to liking-before ordering custom wheels.

I'm thinking about going with a square setup, maybe 265/35/19x10.5 with a 20mm spacer in the rear, 2014 Nismo rims. Any issues with that?

Nismo rear = 19x10.5 +23
with spacer it becomes effectively +3

I know that 20x11 +0 will clear with a 285/30 tire and -2 deg camber

If you have only 265's, you should be fine.

Fronts you may need adjustable front upper arms to dial in some camber depending on your height.

Most folks run 19x9.5 +22 in front with a 265/35. Your wheel will be approximately 13mm further outboard due to the added width

Agreed w/OZ
May need 25 or 30mm spacers on rear to be uniform...(depending camber adjustment).

I'm absolutely clueless about all this stuff. I don't want to buy the adjustable front arms, so to run a square 265 setup, I'd need the 9.5?

Unsure; as if you already have a pair of 10.5 Nismo Wheels laying around & a pair of 265/35’s-Test fit them on the front first.
As they’ll be a bit stretched on the Wheels & shorter than oem spec....you may get away with it...I know a few guy’s running (4) Rear sports 19x10+30 square w/275,285’s...& are getting away with it; but the further you bring that wheel out; the greater the chance for contact while tuning & if you’re gonna track the car any - you’d want more negative camber than oem anyway.
If you’re lowering the car (as you didn’t mention) that’s gonna camber your Wheels in somewhat (pending on springs used)...so unless you’ve seen this setup & running stock suspension-may have to test it out.
Good Luck!

A rear Nismo wheel on the front is nearly 30mm further out than a 9.5” front Nismo wheel.
So if you have 265/35’s on front Nismo Wheels & can stack 30mm of spacing behind them without rubbing (test fit only) then you’re ok...as you’re good on the backside; it’s the contact with fender when you’re turning to watch out for.
Most Track guys w/large square setup Wheels use 18” & about a 25” diameter tire...that helps with clearance...and the 265/35 is 26.3 at best...So check it out & see.
Spacers can be your friend for test fitting how far you can bring one out & then calculate the offset to see if you’re ok; I personally don’t like running them/ but I’m not gonna bash them either.

Many of us with Nismo wheels run 15mm spacer all around and some will run 20mm spacers up front as well. There a lot to work with.

I won't be tracking it, just the occasional spirited back road run. As for lowering it, it won't be much. I'm thinking either the Swift springs or the Nismo suspension if I can find a good used set, but that's it.

So a 265/35/19x9.5 on the back is just fine? I do want a little poke. Any spacer necessary for that? Maybe a 10mm?

I just need to figure out spacing on the front to not rub? And your best guess is a 25-30mm spacer for the front, correct?

Again, I'm sorry. This is my first car like this and the first time I've had to put tires on it, so I'm beyond lost.

Remember something about these cars; the wheel offset differential is roughly 1” or 25mm; so if you’re running identical wheels-you’d want 25mm spacers on rears (+ or -5mm) that’s unless you want the track width wider up front.

That's my setup ;) The added 15mm and 20mm wheel spacers sure makes a aggressive set up when running factory oem tire sizes :tup:

So, just to be clear, to run a square 265/35/19x9.5 setup, I'd need a 20mm spacer up front and a 25mm in the back?

Nope; roughly 25mm more in rear; if you drop on swifts-your camber will go negative more & make it easier for the 10.5” Nismo rear wheels to fit....but looking all through these different threads will help.

20/10" +10 front 255/30
20/11.5" +15 rear 305/30

Iv got SPL suspension parts for the front and rear

What kind of camber you guys think Ill need if Im dropped this much. I already have some what of an idea but the more feedback, the better. Im not even close to an expert on the 370z.

You should probably give us tire sizes, but . .

Fronts: around 3 deg. I have 20x11 +15, 275/30. I'm at -3 camber. Your size (20x10 +10) is 8mm LESS "poke" than mine; HOWEVER, my fenders have been pulled slightly.

You should roll your fenders, and of course, to run that camber, you need some adjustable front upper control arms

REARS: 20x11 +0 fits with -2 camber with 285/30. Your size (20x11.5+15) 9mm less, so you should be more than fine with -2 camber. Stock is around -1.8. Given that you are aiming to go pretty low (top of tire to fender), I suspect you'll need adjustable arms to correct toe, even tho camber can be achieved with stock components

Something like a 245/35/20 F and 285/30/20 rear would be in the ballpark

ops, yeah, I forgot tires. I was thinkgin 255/30 305/30

oh my god reading the responses to this is making my head hurt. Somehow you all have managed to go backward.

let's go back to your original premise:
OEM nismo rears on all four corners (19x10.5 +23) with 265/35/19

These will fit. They'll fit with a 20mm spacer in the back. You might need to roll a fender, the only issues i see are maybe in front. But rest assured, folks have run Nismo rears in front ON THE TRACK regularly with no problems, so it is obviously doable, and they do it with more tire than you, albeit also with adjustable suspension components

Now, I have questions about the limits you're putting on yourself:
1) Why square 265/35/19 all around? Thats LESS tire in the rear than STOCK, which seems stupid. There may be some track suspension setups where square tires are, in theory, optimal, but you arent doing anything like that, so it seems like a pointless, arbitrary starting point

2) you don't want adjustable suspension arms. Well, your post history mentions spending $13K on engine ****, so spending $700 on suspension seems like a stupid thing not to do, GIVEN your odd limitations - particularly since you seem to want more "poke" than stock

All in all, you seem to be clinging to a setup that isn't ideal and isn't what you really want anyways

Proposed solution:
Get a set of OEM nismos
they are 19x9.5 +40 and 19x10.5 +23
Get stock sized tires, 245/40/19 front and 285/35/19 rear

These are 100% guaranteed to fit, because, well, its stock.
These are 100% available, because, well, they appear in the FS section regularly

Put them on the car. See how you like them

Now go to the For sale section here and grab some spacers. 15 or 20mm pop up all the time.

Slap them on your car. See how you like them. lots of people do this. they will fit.

You are making this harder than it needs to be, ESPECIALLY when dealing with an OEM nismo wheel that damn near everyone has

It also sounds like you don't know much about wheel fitment and don't seem like you want to put much effort into this, so that is why I have given you an easy, accessible, affordable solution THAT DOESNT require a bunch additional parts/work

This thread really shouldn't be that difficult

I don't like 305/30 because it's too tall (27.2 in). Stock is 26.9, i dont see a reason to go higher than stock.

More importantly, you may have too big a difference in height from front to rear - fronts are flat 26 inches; rears are 27.2, thats over an inch difference in rolling diameter

That is why i suggested 245/35 and 285/30

you can also probably do 265/30 and 315/25 or 325/25

right on, I did forget about roll diameter, thanks for the feedback man. I know youv had your fun figuring things out. Iv seen your car

I actually went too conservative in the rear - coulda gone with a 325/25/30 pretty easily. But, this was the first set of wheels for the Z so it was a bit of experimentation

As for the engine build/swap, those were also simply ideas I was asking questions about. I'm not sure which you're referring too, possibly both, but either way, both were ruled out for various reasons. I've been extremely transparent in both. In 1 I specifically stated it was a brainstorming idea that a buddy and I had. In the other, it was a legitimate idea, but if you read the whole thing, you'd see I was provided with reasons why it would not be worth it and accepted those facts and moved on.

The reason for that specific size was to be able rotate my tires to extend life, and based on what I've read thus far, 265 is as wide as you can go in the front without modification. It was an idea I had, but as I previously stated, I'm totally new to this, so I asked a question, which if I'm not mistaken, that's what this is for. I have read through quite a bit of this thread, but no, not all 170 pages. Maybe someone has kindly laid out exactly how to do this in a previous post and I missed it. Maybe not. The point here is I am reading on my own, but I'm also asking questions about this I don't understand. I'm happy to admit when I don't know things and ask for the help of those that do. I do not own the Nismo rims yet, and while I understand what you're saying that going from a 285 to a 265 is not the wisest decision, it's still an upgrade for me as mine is a base and currently has the factory 245 on the rear. Again, I'm totally new to all of this, so I'm trying to learn by asking questions that I have yet to run across answers to.

The answer then is you're putting lots of pointless restrictions that are creating unnecessary hurdles

Rotating tires? this is a performance RWD car. It's gonna have staggered tires.

Get over it?



You want tire wear, no upgraded suspension components, square set up, but poke in rear. just all over the place.

Throw on the staggered nismos and some spacers, be done with it.

If you're not willing to go low and adjustable suspension there's no reason try to deviate from stock. You'd just be half assing it.

What wheels you looking at?

those CR2P's?

Oh I already ordered them, Work XSA 04C's...this color scheme

The cr2ps are beautiful but something about the hard edges on these that I liked a little more
https://i.imgur.com/Aa30u1x.jpg

wow, never seen those on a Z before. cool

we'll see how they look..cross them fingers! My Z is black as well, I photoshopped that brz black to make sure I liked the combo.

****, somebody must've had a bad day. I didn't know all of that would be necessary. I know somebody with 265s on the back, but no spacer. So, I was thinking with spacers, I could get the poke. And I said I wanted to make some suspension changes, but the car won't be tracked, nor will it have any excessive camber, so I saw no need for $1,500 coilovers or a total suspension overhaul. I didn't know that replacing any components would be necessary for what I asked. Now, thanks to your grumpy response, I do, so thanks, I guess.

te37 19x9.5 +22 front on 225/25 19 and 19x10.5 +22 rear on 285/35 19, im trying to get a flush tire to fender fitment with less possible camber(-1 or 0) while being slammed, would this work out

Your rear tires are my front tires. :rofl2:

Front wheel is a pretty common fitment. Rears are going to need 15mm or 20mm spacers to even out the "flushness". Where did you come up with the wacky tire sizes?

They’re local buy I was just tired of of wheels, I’m currently running 20x10.5 and 20x12.5 with 325 in the rear

your front tires are almost everyones rears, if not bigger!
