Thanks man. My offsets are:

19x9.5 +41
19x10.5 +27

I see, pretty much like nismo wheels, any spacers?

I have a 93 mustang coupe and the rear wheels bolt right up to a 370z with base brakes. Mustangs are 5 114 bolt patter which is the same as our Z. I run this mt slicks on the Z sometimes when I take it to the track. So yes use the 370z base brakes. Plus it looks sick!!

Well how wide are they?

Don't know what that means but very nice background defocus, if only it was a meaty tire too :tup:

They are a 10 inch in width.

285/30/20 on 10.5's on all four corners with +25 offsets, has anyone tried it? My wheels come in on Wednesday and I'll find out one way or the other.

So ideally that should translate into a 255 tire, but tires are never exact this one's probably wider.

The Z is not made like a sedan to take a square setup. It is meant to take wider tires and wheels with more aggressive offsets in the rear, like how the oem wheels are.

Outside diameter and inside clearance to suspension components will be fine in both front and rear, however, there will be an issue with the front coming out past the fender, which besides looking strange could cause fender damage over bumps/driveways/potholes/dips/ect.

10.5" wheel with a 25 offset is 2mm shy of the oem nismo rear wheel, so in the back they'll be fine, you could even use a 10-15mm spacer or so to make it flush with the fender.

For the front, a 10.5" wheel with an offset so aggresive will come out quite a bit from the fender, and there's nothing you can really do about it unless you make your car widebody haha.

According to calculations, your front wheel/tire will stick out 35mm (1.4") further than a stock nismo wheel/tire (19x9.5 +40 on a 245/40R19 tire), so that should def be outside the fender a bit, and the rear would he inside the fender a bit. :ugh2:

No spacers btw. Sorry for the late reply.

I have a question and please forgive me if it's all ready been answered on this thread but I just recently got 275/35/20's in the front and 315/35/20's in the rear and ever since my traction control light won't go off. I'm not sure why this is but I'm guessing it's because of the meats. Can someone please enlighten me. Thanks in advance.

What make of tires do you have? If you know the specs on them. Then you know the tire height. Too much differance in tire diameter will make the light come on. Thinking that you have too much differance in height. You would be better off with a 315/30-20 in the rear.

:eek:

The reason more than likely is because of your tire sizes. First, your rear tire is a whopping 8% (6.6") larger in circumference than original, but that's not the problem.

The problem is that you have a 4% (3.5") difference in circumference from front and rear tires, this would throw the VDC ecu off because your front and rear axles will be turning at different speeds without any steering angle.

Your front tires will be spinning faster than your rear on the axle, making the VDC ecu think there is wheelslip (although impossible due to the fact the Z is rwd and there's no way the fronts would be spinning faster than rears unless you're locking up the rears with the e-brake but that's beside the point, it still throws off the computer)

Three different ways to solve this:

1. Turn off your VDC everytime you start your car.
2. Replace rear tires with 325/30R20
3. Replace all tires with tires that are closer to factory diameters like 275/30R20 front and 325/25R20 in the back.

good info :tiphat:

when i decided to go wider i checked many different options and brands to make sure i got close.

my set-up has identical circumferences F/R of 26.3"

265/35/19 F and 305/30/19 R

I'm on the edge with my sizing. 275/35-19 (26.6") and 345/30-19 (27.2").

Thanks guys. They're nitto invo. We went with these tires because of the wide body. The rear wheels have a huge concave so the two look amazing together but I guess I'll just have to live with the light or turn the vdc off. One more question... Can this damage anything long term or is it just having to deal with the light?

Besides a possible safety issue with vdc, if it doesn't work than you don't have it, if it does, it might work improperly so I'd just turn it off and pretend youre driving an older car without the driver aids like I always do anyway :)

Your abs may also be affecred, as well as brake force distribution. It is really not a good idea to have different front and rear diameters with so many electronics in the car but as far as damaging something, I don't see what you could damage unless it causes an accident, but you should be able to feel if any of the car's characteristics feel dangerous at the limit I guess.

Np, it's a nice setup...I love wide front (& rear obviously) tires, but the fronts are more rare to see that wide. :tup:

but.........345s are worth the difference :yum:

You're only at a 2.1% difference, he has a 4% difference. There's the problem :)

Next time get 295/35R19s for the front and you'll be at 0.1% of a difference...then again those are really expencive and hard to come across, but 285/35R19s are everywhere and they're still closer than the 275 obviously, they're at a 1.1% difference from your 345 :tup:

I might move up to the 285/35-19 when I need front tires, or go even bigger if I can $$$ for new front rims.

Hey if anyone is interested I'm selling my meaty wheels and tires. Hit me up!!

R.K.

Some info/specs/pics from them would probably help you sell them :)

GLWS :tup:

Thanks. I have them listed here:

R.K.

yep & looks very good,,,,probably not much ride difference between the 19's & 20's............great fit!

Hankook RS3 275/35/19 305/30/19. Fronts rub on 9.5 +12, rears are 11 +11

ohhh my lord... damn dude looks perfect... love the fitment of the front tire :drool: the front rub too much or just a little? i have a 19x9.5+12 with a 245/40/19 and rub a little... more in the highway big bumps... but im definitely interest on install front tires like yours :p

**** that looks good

what are you alignment specs?

Thanks! They rub often... very often lol. I have since raised it another .3 - .5. I plan on dialing in some camber to help w/ the rub.

Thanks :tiphat: I was at -1.5 and -1.6, but I haven't gotten an alignment on the new wheels yet. I'll most likely get it in spring time.

That's some great fitment

awesome!!! thanks for the info dude!

Need some help guys...

My wheels are now finished being produced - Specs:
Fronts: 19x9.5+20
Rear: 19x11+15

https://igcdn-photos-h-a.akamaihd.ne...47796053_n.jpg

I'm lowered on Swift Springs and shocks are Koni's... No camber or toe arms at this moment, but will be getting some soon.

I'm wanting to run 265/35/19 in the front... I don't think that will rub.
What I'm really needing help on are the rears. I want to run a 325/30/19, but fear they will rub... I know I can get a 305 just fine. Does anyone have any experience with those offsets and a 325?

I will be ordering the tires this weekend. Thanks for anyone who helps!

Proper meaty ! Looks good

Meat!

:yum: meat...

I wouldn't call it meaty as much as I would wide. Now on 10.5 +15 and 10.5 -5, 285's are all im going to be able to run till I get a wider body.

^ How much front camber do you have? It doesn't look like enough on the fronts. Are they 18x10.5 RPF1 +15 square with 20mm spacers on the rear? Any more pictures?
