Cause i need to raise the car to fit these, so its gonna be done at the shop, i have a feeling they won't fit unless i jack up the car past stock height which i dont want...i want flush fitment

Hey thanks for the reply, much appreciated. Perfect so it's the tires front & back that will not fit? What do you suppose is the perfect spec tires?

265/35/19
305/30/19

You want flush fitment but you,dont know anything about wheel sizing

You need to read this

http://www.the370z.com/wheels-tires/...tart-here.html

Coilovers and SPL arms are required

What is the most aggressive tire/size that I can put on a 19' rear Sport Ray rim? Any suggestions are greatly appreciated!

I'm interested in the TC105X. I'd like to run 18x10.5 all around, the wheel comes with either +12 or +25 offset in that size. The +12 offset would be preferrable, is anyone running 18x10.5 TC105s up front and if so what offset did you choose? Just want to know if the +12 offset will clear the Akebonos.

I doubt the 18x10.5 will clear the Akebonos. Caliper clearance is dependent upon pad size, barrel diameter, spoke articulation. Both of the offset sizes offered only come in Weds' RR face which is the most concave of their three face designs. You might be able to run a spacer though I'm not sure what size and you may have to pull/roll the fender and/or run more camber. Rears should fit.

It's a track oriented wheel so they may have designed it for a good amount of brake clearance

OTOH, when I had some Work Emotion XD9's, i found out the hard way that wheels designed for "Rear" fitment had a thicker inner barrel, with less clearance diameter-wise.

generally you will need to check for your specific wheel with your manufacturer/retailer



ALL THAT SAID

You are a lucky SOB. See here:

18x11 +15 all around

Well, there's your answer. I stand corrected. The 18" RR face will accommodate the Akebonos. Good looking out OZ!

OptionZero and k67p67, thank you both very much for your input! I will gladly be purchasing a set of four 18x10.5 +12 TC105Xs soon. I'll post some pictures in the 18s thread since there doesn't seem to be anyone on the forum running them in that sizing.

Hey guys, will 18x9.5 +25 ET wheels fit front? I plan to put there 265/35/18 tires (cuz of cheap semi slicks). I've put the wheel (without a tire) and it didn't clear the fender (it was sticking out 15mm), but I guess that's because the car was lifted?

wheels will always look like they're poking when lifted

9.5 +25 is a common width/offset range for front

What size of tire will fit
 

2016 370Z Base model
18x8 F - 18x9 R
Currently running 245 40 r18 F and 275 40 r18 R
Looking into getting some street radials but don't know if I should or can go a bit wider on the rear on the stock wheels. Thus the reason for the post. Want to go 285 40r18 (0.3" diameter difference) which is okay from the little bit of tire sizing that I understand. But my question is will a 285 fit on 9in wide wheel? Or any recommendations on street radial setup for the stock wheel sizes I have. Thanks in advance.

Can you run a 285 on a 9" wheel? That is a bit wide for a narrow wheel, but yes it can be done. However, you can't run 245/40 with 285/40. That's over 5% differential in diameter. VDC is not going to like that. Alternatively, you could run 245/40 with 285/35.

A better solution would be to get some wider wheels.

285/40
 

Rear stock tire size is 245/45 so if im going with a 285/40 its only a 1.06% (0.3")diameter difference according to Fitment industries tire calculator. Not sure at what percentage difference it starts messing with VDC. But yeah main question was that if 285 would fit on 9 in wheel.

Comparing a 285/40 to the stock 245/45 is irrelevant given that you're not running the stock tire size in front. The VDC system starts to get temperamental when the front/rear tire diameter differentials exceed 3%. As I mentioned, a combination of 245/40 and 285/40 will result in a diameter differential of more than 5%.

Can depend on the tire, but Michelin PS4S says 285 should be at least 9.5” wide

Will 275/35/18 fit in the front of 370z?
 

Hey I am a proud owner of a 2014 Nissan 370z and I am currently looking for tire setups. Will a 275/35/18 tire fit on my front wheel size and front fender without rubbing?
My Front wheel specs: 18x9.5 +15 mm.

295/35/18s fit 10.5 + 15mm
 

Will 295/35/18 tires fit on 10.5x15mm for the rear fenders without rubbing? I am on eibach prokit springs.

Got a deal i couldnt pass up on some rays 57cr 18x10.5 +12. Currently has 305 30 19 on stock rays KW coilovers not set low. Trying to find the best option for some stickies for the 18s. Would 315 35 18 fit? Looking at sizing options for the best price and I can't keep it straight what to go with. 295 40 18, 305 35, 295 30 or 315 35/30 ughhh anyone shed some light on this for me?

I have 275/35/18’s on the front 18x9.5 +22 of my Sport.

Base 370z Enkei RPF1
 

Fronts:
18x9.5 +15 (265/35/18)

Rear:
18x10.5 +15 (275/35/18)

Coilovers:
BC racing DS (Raised the fronts basically at stock height after noticing rubbing, rear dropped about an inch)

At 26.25 inches from ground to fender and had some rubbing up front and was bottoming out on speed bumps.

This is what I have on my car right now. What can I do to help with clearance and stop rubbing..? Get new wheels, tires, roll fenders, or am i ******?

I'd like to be able to get 245/45 in front maybe or 255/40
Rear I'd wonder if 275/40 would fit

Thanks

First step is to read this:

Your fronts are more aggressive than your rears. A +22 would be more consistent, and in line with fairly standard 370z aftermarket sizing

Additionally, your front tire size is very wide. While a 265 on a 9.5 width wheel is within the acceptable range from the tire mfg, it is pretty “over square” from a fitment standpoint. Even Nissan itself uses a 245 width tire on a 9.5 inch tire (such as on the front of a nismo)

I would go down to a 245 front, roll your fenders, and see where you’re at

Bear in mind, however, the Z has no front camber adjustment from the factory, so your camber is whatever. At ur ally results from lowering the car and the condition of your bushings.

For full, reliable adjustment, you need new front upper control arms, the best option of which are from SPL parts

Summary:
Easy solution is swapping to a 245 tire and +22 offset wheel

Best solution is rolled fenders, adjustable arms. At that point you can run any front wheel you want.

For street, I have run a 20x11 +15 front with a 275 and currently run a 20x10 +3 with 255
For track, people regularly run 18x10.5 or 18x11 with a 275 or 285 or even 315

The Z can fit anything, if you do it right

Would it be too crazy to try to get a 245/45/18 and a 275/40/18 on the rpf1s? Im gonna roll the fenders for the fronts, i guess probably the rears if im going to increase the sidewall

Ill do the SPL parts if its really necessary, but wanted to hold off until i save up some more and get more mileage out of stock parts.

you can try those tires

Stock rims. Not lowered. Looking at 245 45 18 in the front 275 40 18 in the rear. Will I be ok ??

the OEM 19's come in the same width tires so you should be fine

Thank you
I was just worried with the offsets in the rear the 18s are +15 and the 19s are +30

rear fitment is never an issue, the Z34 can fit anything back there
even a 9.5 +15 in back shouldn't pose a problem

Awesome thanks

Well, it has time to purchase some new tires for the first time since I bought the original set.


I would like to go a little bit wider in the rear, while staying with in the proper Circumference percentage of the front to the rear, so as not to freak out the computer.


Here is my current set up on stock suspension.


20x9 +32 Front 245-35-20
20x10.5 +25 Rear 285-30-20


Question 1. What size should I go to in the rear if I were to keep the same size in front? 295-30-2? or go up to 305?


Question 2. What combination would work best, if I were to go wider in the front as well?


Thank you for the help.

Thank you.


I am aware of tire calculators and have used them many times.


They are very helpful when trying to decide on rim offsets and clearances. I am not sure if they are so good on telling me if the front/rear tire combo that will not freak out our computer. I believe the ratios between the front tire and rear tire circumferences has to be within a certain percentage. So I just want to make sure that I do not exceed that prior to buying a set.


Thanks again.

If you bumped up front and rear by 20mm to 265/35 and 305/30 you’ll have the same .4% difference in circumference as before, which is less than 1% so you would be fine. And with your wheel offsets I suspect these bigger tire sizes won’t be an issue

will tell you speedo error if you put front in the left and rear in the right

Ok. Thank you.




So, Please correct me if I am wrong, but if I wanted to keep my current fronts, I could go to 295 in the rear. It is 0.8% difference in circumference which is still under 1%.


Right?

No more than 3% difference.

anyone have any pictures/feedback of 19x9.5 +38 19x10.5 +30? Looking at buying some used 57 Transcends.

Tires that would be mounted are 285/35 and 255/35

Those offsets are a little weak but you could get around that with spacers. 9.5F +22, 10.5R +22 is a good “safe” setup.
