Be ready to take your spacers off and raise the car a little. You may or may not have to. I gotta put my coilovers on one day soon.

Idk about lowering, but on stock '12 touring sport ride height I have 10mm spacers upfront, 2.5mm spacers in the rear...making my effective front offset +30mm and +20.5mm rear on 285/35R19 / 325/30R19 tires with no rubbing and a prefect flush-to-fender stance.

Did you guys need more than 35 psi on the tires when running them oversize like this? I got 265 RE-11s on a 9 inch front and at 35 psi it looked half-flat. 40ish looks better.

:icon14:

Noop, stock pressures.

ditto

The tires are wider than original so yes they're gonna look more bubbly on the wheels and therefore look more underinflated. But...they're not underinflated. Infact, the tires having a larger surface area would require less psi in them to hold the same amount of weight, so stock pressure or less...but not more and certainly not 40psi.

Anyone running this set up 285/35R19 (F), 325/30R19 (R) with Swift Springs?

i always stick with the factory sized tires, the engineers have it figured out.

Ah, no they don't. My car is basically stock. It is a big difference. It is not always about the engineering. It is about the money (bean counters).

Not exactly. It depends on what you want to get out of the car. The engineers have to account for too many variables in their design and execution to maximize the Z's performance. Safety requirements and cost are probably the most severe restrictions.

Engineers did a superb job on the concentric slave cylinders ;)

This.

If you run stock wheels I dont see why they wouldn't fit without spacers

:iagree: As well as the heat soak issues with the VQ

Hey VinceThe1... appreciate you paving the way w/ the 285/35 R19 Front and 325/30 R19 Rear on Nismo rims w/o spacers... that's going to be my setup come spring. I like Rusty's thinking of go big w/ the 345's but that is a much more involved setup w/ new rims/spacers/alignment...perhaps later down the road for that.

I have my Nismo tires/rims off now for winter but I plan on getting my rims powder coated over the winter and will need a fresh set of rubber on them...looking at the RE-11's in those sizes. My original OEM S0004 tires have about 18k miles on them and my rear tires are just about worn out to the thread wear indicators so I can't use them up front. Have to go with all 4 new.

Currently I have a set of Blizzaks LM-32's (square setup 225/50 R18's) on my car for NJ winter that I just got from tirerack w/ A9 rims for about $1500. I'll be riding out the winter with these.

Now I just need to find a sweet deal like JaviZ did on eBay and I'll be all set!

Cheers :tiphat:

Thanx! Since I'm running my current setup I have installed spacers. I put 10mm upfront to get them really flush and I put some 2.5mm in the rear just because, can't really see a difference there. Works great without spacers but I just wanted a wider front track and to have a flush look. My rear Hankook V12s were pretty camber worn down to almost nothing on the inside and I'm still driving on them well over a year and 12k later lol. With stock suspension the front doesn't camber anything like the rear so the tire actually starts stepping on the unworn outside when you put it in the front and you can get a lot of life out of an otherwise worn out "rear" tire that way. I would recommend using your rears upfront unless you want to shell out over $1200 for a brand new set all around.

With OEM wheels and those tires, simply lowering can't be an issue. I even have 10mm spacers upfront and 2.5mm spacers in the rear now to make everything flush and still no rubbing (at stock height). I'd say you're pretty safe just lowering without spacers, then if you want add 10mm spacers upfront to see if that'll clear...but with stock Nismo wheels and these size tires you shouldn't have and issue at any height (unless you use camber arms maybe).

I totally agree, everything is a tradeoff for manufacturers especially these days...and while it's true that there is little to no improvement in actual "performance" by putting beefier tires on your car, it makes the car look better IMO and it definitely extends the life of the tire. Does it make the car slightly slower and less fuel efficient due to the higher rotational mass of the extra rubber? It must and probably does but I can't tell by butt dyno or by personal observed mpg.

thinking about getting this setup on my 2015 nismo. any reason they wouldn't fit? anyone have the offsets on the new nismo wheels?

Any reason this setup wouldn't work with 15 nismo wheels I'm about to buy this size re-11.

Vince.....................YOU ARE THE F-N MAN!!! This setup looks so sick, just did it today. Went with V12's since I am on a budget (expecting a new addition to the family) and don't track/drift/race/etc etc. Although every now and then I do a little spirited driving.The ride feels 10x smoother and I know because this is my DD, the grip is sweet, honestly it feels like a new ride, and it looks bad as ****. I posted pics in the meaty tire thread. No spacers needed... flush on the rear and almost flush on the front. I needed new tires all the way around anyway so I took your setup and I am so glad I did. Thanks again cheers:tup:repped you for getting this out to us.

Does anyone have the old nismo offsets compared to the new nismo wheel offsets?

I love this setup guys. I want more meat on my tires in the sidewall. I want a thicker tire to help with road noise, cushion, AND space between tire and lip. Could I go with 315/35/19 in the rear and be ok with rubbing?

what alignment specs are you guys running?

Hi mouse!

The redesigned 2015/2016 Nismo wheels have the exact same widths and offsets as the 2009-2014 Nismo wheels. You shouldn't have any issues running this setup.

I fitted 285/35R19 RE-11s to the front Nismo wheels. Love them! But yea...the new Nismo wheels are just a different design with the same specs.

Thanx man! I had the V12s on the front and recently got RE-11s (just upfront, still wear the coopers in the rear). It's an awesome setup, with the extra grip upfront it corners hard but could be dangerous as it bites so hard the rear wants to swing out during hard cornering without even hitting the gas now...almost like an MR haha

315/35R19 would be way too large of an overall diameter, 325/30R19 is really close to the stock 285/35R19 in diameter. Idk if you'll rub or not but you'll have massive sidewall and a huge tire...I wouldn't step away from factory overall diameter, atleast not that far.

I'm running stock Touring Sport alignment @ stock ride height. I do have 10mm spacers upfront and 2.5mm in the rear now and still don't rub. (didn't have the spacers on the original pics)

Setup ordered!! I'll be in the club next week. Ordered RE11's in 275/30R19 F and 325/30R19 R for the Nismo. Will most likely have the tires installed, take the car to have the AC system evac'd and then to the garage for BP single install. Tires just in time for massive power increase.:happydance:

Tires arrived today. Sending the 275/30's back and waiting for next Wed for the 285's to come

Edit** 285 arrived today (Monday) already dropped off at tire shop for install tomorrow morning. Pics to come.

:happydance::stirthepot:

I feel sorry for the guy who had to mount those rears. Wide tires on a narrow (in context) wheel isn't fun.

Are you suggesting that 275mm tires on a 9.5" wide rim and 325mm tires on a 10.5" wide rim are too wide?

IMO, yes. I currently have a 265/35 and a 285/35 setup on my sport package rays, and I don't exactly like how they feel on the dragon. However, they are the first tires i've run in this sizing, so I am holding total judgement until I can try out another brand once these wear out.

The 275 on a 9.5" wheel is fine, but a 325 on a 10.5" wheel is too much for me. i would want an 11.5" to a 12" wheel for that size.

Congrats! You had 275/30R19 for the front? Good thing you sent those back as they're far too small in overall diameter. They should be 275/35R19 or (even better) 285/35R19. Are your 285s 30s or 35s?

Depends on the tire, if it's a stiff sidewall runflat then yes, they're probably impossible to mount. My coopers however fit relatively easily, I watched them install them and it didn't look like like they had any difficulties whatsoever.

To each his own, I hate the stretched look of the original 245/285 setup. Do meaty tires make the ride floatier? Sure, but barely. I love the composed ride with those tires and they really protect the wheels..and I don't mean from curb rash, I mean from bumpy roads, DIPs, potholes, etc.

To anyone that wants to install stretched and/or really low profile tires on their wheels on anything by a show car, don't. Even with forged wheels, you need adequate tire sidewall to cushion the blows sometimes experienced on regular roads. I know from experience...I bought 4 brand new front 19x9.5 +40 2014-2015 Z34 Nismo FORGED RAYS wheels for my Acura TL, then fitted 275/30R19 Nittos on them...and now, after a year of daily driving, when I put the car on the lift, 3 of the 4 wheels are slightly eggshaped. No such thing with my beefy tires on my Z...trust me, NO wheel is strong enough for daily driving with rubberband tires. Whoever doesn't believe me can experience it first hand.

It is much better for the ride, your wheels, your tires, your suspension, your kidneys, etc. to have a respectively narrower wheel with a wide, meaty tire than to have a wide wheel with a respectively narrow, skinny tire.

The fronts are 285/35. RE11's don't come in a 275/35. And the tire guy was hating life. This setup rides better than the stock setup did.

Hi VinceThe1,

From a rim protection stand point, I agree with you.

From a performance stand point...I do think that there's a diminishing return. I've always thought tread width should closely match the rim width (measuring inner barrel, not lip to lip).

Measurement #'s from TireRack:

Tread Width - 285/35/19 RE11 has tread width of 10.4", which practically equals the Nismo rear rim width. The measurement is from the tire mounted on a 10" rim, so mounting it on a 10.5" inch would give it a slightly bigger tread width #.

Section Width - this is sidewall to sidewall width, same tire is 11.4". I think Nismo rears is around 11.5" lip to lip. Looking at my rears, the tire sidewall looks to be flat, if not at a ever so slight angle, so I see your point on rim protection.

However, with 325/30/19, tread width of 11.5" was measured on a 11.5" rim. Mounting it to a narrower rim will decrease the actual contact patch. I don't know the exact math, but I want to point out it the tire treads across the width aren't getting evenly pushed to the ground, hence not quite effectively being utilized. As far as ultimate grip goes, 325 probably still beats 285 on the same 10.5" rim, but I think mounting overly wide tires onto relatively narrow/skinny rim width that's out of range shouldn't be used as a blanket conclusion IMHO.

My theory is for street tires. Slicks are something else.
