I would increase both of those sizes a fair bit myself. Like 285/305 or even 325.

Then again in running 275/345 so I err on the side of "I can't stand stretch!"

Really I'm only trying to illustrate that 245/285 is going to be ricodulcoursly stretched in those rims. With +10 rear you may not want to go all the way to 325 but 305 for sure.

Not want a stretched look at all, I'm new here thus why I wanted to ask. The wheels I previously purcahsed were 20x10 20x12 and I was going to run a 255/305 on those as the guy before did and they didn't look to stretched. I have no problem going with a 255/305 on these wheels, or even a 265 I just want to fit in the stock fenders without issue. I have coils and rear arms at the moment I will be installing at the same time. I come from the Honda world so I'm use to the smaller 15/16 wheel tire combo.

I also figured since the stock Nismo wheels are only .5 less then the Works I purchased the stretch wouldn't be out of control.

I'm thinking a 265/305 might be the way to go.

You'll never get an exact prediction for a specific size (unless you manage to find someone with literally the same setup) because even for the same size among different manufacturers, the tires will not fit the same

For example a Michelin PSS and a Bridgestone S04 both in 245/40/19 will fit differently on a 19x9.5 wheel. This is because they have their own designs, and the tire's shoulder will be more or less rounded or squared off depending on the manufacturer. Some tire companies/models run "wide" while others run "narrow" by a bit

For a more or less "square" shoulder, i think a 325/25/20 is right on the money for a 20x12 wheel. A 305 is only 20mm less so you'll get a slightly stretched look (rim edge exposed by tire).

This isn't a "problem," so much as aesthetics.

Some people freak out when the tire isn't completely covering the rim edge, but thats just them.

Others have the entire freakin' mounting surface exposed in a hellaflush setup.

And there's everything in between.

I think your sizes are fi"ne, assuming you are running a 255/35/20 and 305/30/20

Yea I hear you, I've run tires that are the same width by number but the actual tire was much wider like when I had Kumho XS in a 215, they were much wider then other brands I had on the same wheel in the same size.

I'm going with a 19x10 19x11 wheel setup now, decided to go with 265/305 I think that should be find on the wheels, and tire rack has a close out special on some Continental tires in 265/35/19 and 305/30/19.

TE's look great BTW, those or ZE40's will be next for me.

Also you gotta look at where chase is coming from. See his build thread and he's all about that buldging tire. It's not my cup of tea

When he says ridiculously stretched, that's his valuation.

I qualified that right away. ;)

And I was originally planning 325's but somewhere between that decision and purchase time they became unavailable, so it was either go up or go down. I actually mounted a set of 305 drag radials on my rims and the fit was ok (they run wide) but I would have needed a 10-15mm spacer at least. So it made sense to spend $0.00 and go up to 345 instead of $150 for spacers. Especially as I'm looking for the dig.

I think he's well on his way to the larger side of conservative, and that's probably perfect. :tup:

My front's are 19x10 w/285/35's....your +10 offset is going to be just over an inch further out than mine are.
I got factory front camber-0.75*



Sent from my iPhone using Tapatalk

Gonna drop around 1" or so pretty soon.
sorry about Huge pic.

Zero;
How low is your ~Z~ from stock....getting down there.
And yes/Chase is bulging somewhat w/345's on 10.5's...as my 345's on 12's don't.
The Invo tires are nearly 1/2" narrower on the section than the PSS's & I wanted to ensure I tucked that 8" of backspacing underneath without spacers.
Lightly shaved the huge head from the traction arm bushing & used a button head bolt to secure it.(.25" clearance there & .50"@shock) snug/ but no rubbing,scraping,etc...
I'm gonna drop around 1" & maybe a tad more in front; just have to get some SPL parts in first.
Plan to keep the same camber setting of -0.75 all 4corners/ as I don't track my car.

I played around & made a large protractor,to determine the amount of wheel lean at a given degree at a given tire height.
Seems like with a 26.5" tall tire; it leans 7mm per degree of camber....I'm sure this could vary a tad,,,but I'll have to see if I can round it up.

Don't Shoot;
looking back & confirming chart,,,almost 1/2" of wheel lean per degree (.47") on a 27" tall tire & (.45") on a 26.25"...shorter tires would be slightly less & slightly more for taller ones.

Hello all! I'm looking at getting a new wheel set up, but I'm not a fitment guru..
I'm looking for a good fit with stock or close alignment, no crazy camber or anything. I have kw v3 coils in the garage but won't drop it much. Only to about 1-2 fingers width of wheel gap. The sizes I'm looking at are
20x9 + 25 & 20x10.5 +15 with 265s in the front and 305s in back
but I don't know what aspect ratios to pick, or if this fitment is good. I don't want my wheels to stick out past the fenders at all. Any opinions on this set up? Advice? - thanks in advance!

That sounds just about right. Will be flush stock and tuck just the right amount with a little drop :tup:

27" diameter tires put your speedometer accurate & fill the wheel wells;
If you have a particular tire brand/model in mind-that would help,as they all differ somewhat on fitment.
TireRack perform's a measurement on a suggested wheel width size & then gives you a range...The 265/305 in 35/30's are 27.3"/27.2" tall in a Michelin & the same 265/305 in 30/25's are 26.3"/26.0" tall (slightly more negative rake)...both of these tires were measured on a 9.5/11.0" wheel.
In Michelin; A 255/35,295/30 are both 27.0" tall & measured on a 9/10.5" wheel.
So you get to choose on what you like.....w/4.08 gearing out back;i'd personally stay with the taller-closer to oem diameter rubber.
Hope this help's,as i run 26.8"F/27.2"R on mine w/19" wheels.......it's all in what you like/as with oem camber & your wheel spec's-you should not poke.

Side view & slightly leaning/not lowered any.https://uploads.tapatalk-cdn.com/201...7525535e50.jpg

Awesome info! Thank you so much! Yeah, I would like to stay close to oem if possible.

I wasn't sure of which tire brand to get but I want something decently sticky from a stop. I was thinking Nitto nt555 gen 2s... I like the invo's but I heard they have the same amount of grip as the toto T1 sports, I had those and I'm looking for more grip... but it is a daily so I'd like decent tread life and not loud af too lol

Sounds like you want either Pilot Super Sports or Pilot Sport 4S

Stick tires/Quiet/Long tread life....sounds like an expensive tire.
The 20's are getting more sizes available in the 26.7-27.2 range...but not as plentiful as the 19's.
Unsure your price range, but Michelin seems to sound like what you're looking for in s tire.
These new Continental tires actually look like a Michelin & cost just as much...My Invo tires are actually quiet & are very smooth riding.
Z will still light up those 345's-even with the 3.357 gearing.
I usually go through 2+ sets of rear tires to 1 front; but have been easier on the pedal with this last set.https://uploads.tapatalk-cdn.com/201...d834b2b23f.jpg

So much great info! Thanks everyone!! Treadlife is my least worry I guess, as long as I'm not changing my tires 2-3 times a year I'll be alright. I'd like to stay at or close to a grand for the set if I can give or take s couple hundred.

Hey guys I was wondering if yall could help me out with wheel setup. I have a chance to getting CE28n rims and was wondering if my current tires would work out. I ask because I just bought Michelin PSS like 5 months ago and would not like to spend more on tires. I am also on KW V3's so I can adjust height of car up/down if needed. I would not like to have excess camber as this is my daily driver. Thanks for the help!

Brakes:
Sport Package Brakes

Suspension Setup:
KW V3's
SPL camber
SPL front upper camber arms

current setup: Nismo Wheels
Front Rims: 19X9.5
Front Tires: 275/35/19
Rear Rims: 19X10.5
Rear Tires: 325/30/19

Possible Setup if Yall say it will work out fine: CE28n 19'
Front Rims: 19X9.5 +22
Front Tires: 275/35/19
Rear Rims: 19X10.5 +22
Rear Tires: 325/30/19

Get wider rear wheels with lower offsets. 19x11 at least with +10 or less offset, depending on how aggressive you want to be. My 19x11 +15 rear wheels setup with 305/30 tires, for example, was too conservative for my taste so I installed 5mm spacers. Even without a camber adjustment, I could've gone a few mm more. Even if you get a bit of negative camber, you should be ok.

Factory Nismo wheel's are:
19x9.5+40F
19x10.5+23R
if you can run a 20mm spacer up front, on your current set-up(without any turning issues)that would be equivalent to a 19x9.5+20....then the +22's will be fine.

As /Angelo350Z/ mentioned,,,your rear wheel's will be sunk in compared to the front/a 10-15mm spacer may be required on rear's to pull even w/front's on new wheel's.

Hey folks, just wondering if I should have any issues with fitment on a 2016 Nismo Z. I've already purchased a set of Weds Maverick 709 rims with the following measurements :
Rear 20 10.5 +15
Front 20 9.5 + 20

I'm going with Swift springs but wanted to get a decent size set of tires for looks, ride and contact patch. Would the following tire sizes work?

305 30 20 rear
275 35 20 front

Worried more if the fronts would rub....

Sent from my SM-G860P using Tapatalk

Front are way too tall, over 27inches

U want 275/30 or 255/35

Wheels will fit. Pretty conservative

You should be good other than your front tire height! Just get your alignment dialed in after your springs settle with the new wheel and tires! :tup:

Much appreciated! Thanks!!


Sent from my SM-T217S using Tapatalk

If you don't mind the negative rake & possibly more than -2.0* camber up front.
You may have a better chance with 285,305/30's (26.8/27.2) slight rake & full fitment on wheels.
But I know Jason is the man & he's seen more wheel/tire combos than me!

Here's one to chime in on:

Wheel specs:
19/9.5 Et +23
19/11 Et +13

Thinking these tire sizes:
245/40 R19
295/35 R19

What do you guys think?

Specs are fairly usual for a 370z. Would go 305 rear and 255 fronts. to avoid any stretch but that's me. Should fit no problems

Yeah was thinking the 265/35 and 305/30 combo but it's a bit to short and walled out for the ride height I'm at. The 245/40 looks fine was trying to see if I can get just a bit more rear contact by going 295/35 on the rear while maintaining the over circumference.

How much neg.camber are you planning to run (-1.0'ish F,-1.5'ish R)?
with front spacing @4.33"F & 5.46"R,,, a tad more negative out back is gonna be needed to even out w/front.
I'm thinking 275/35,325/30's...but that's meaty & with the coilover's; you should still have room.
It's a full fitment & no stretch....26.6/26.7" diameter...otherwise 255/40,295/35's.
Ton's of option's with all of your suspension parts.

Will these fit and look right on my 2016 Nismo
 

9J x 20” 5/114.3 ET25/35

Ferrada FR3's

Looking for a flush look lowered on Tein S Springs
Thanks guys

Martin

The more flush setup will be the 20x9.0 +25 Front and the 20x10.5 +15 Rear. Though those are a very easy fit with wide tires. I call those sizes semi-flush.

Yep, like Kamispeed says,,, very little or no negative camber needed with 25/15 offsets.

Thanks guys, appreciate any help you can impart.

Hey guys, I could use some help. I have some 19x9.5 +22 and 19x11 +11 wheels that needs better fitted tires. I have Michelin PSS 285/325 35/30 on them and I'm getting rubs. Mostly in the front (I don't have aftermarket camber adjustment) but in the rear I'm having to put my camber at around -4.5 to keep the poke and rubbing to a minimum. Without the excessive camber the tires poke about 3/4 of an inch at stock camber. I would rather not have so much negative camber so I can utilize my tire a little more. Should I go with the usual 265/305?


Sent from my iPhone using Tapatalk

Yep; with minimal camber- you're out there pretty good.
4.38"front spacing on front & 5.54"out back...if you're wanting to keep close to stock diameter & speedometer be accurate 255/40,295/35's


Sent from my iPhone using Tapatalk

I know those sizes are a punch in the gut,compared to what you have now...yours started at 26.9"F & 26.7"R (pending mfg.) pending on weather or not you go low; 265/35,305/30 is definitely fatter than I suggested earlier. & both 26.3"

Hey guys, will I need anything apart Front camber arms (I have z1 ones sitting in a box) for
TE37SL 19x9.5 +22 / 19x10.5 +12 with 265/35 | 305/30 Michelin PSS that is sitting on RS-R springs Front -0.4inch to -0.6inch / Rear -0.4inch to -0.6inch?
