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.
