Why you should use these tires with NISMO Wheels: 285/35R19 (F), 325/30R19 (R)

Considering going this route with tires on my 2014 Nismo. Will these tires still fit with lowering springs? I was thinking of going with Ark-GTS or Swift springs. Now the

Considering going this route with tires on my 2014 Nismo. Will these tires still fit with lowering springs? I was thinking of going with Ark-GTS or Swift springs. Now the Ark-GTS is apparently lower than Swift so wasn't sure if it would have camber or rubbing issues. Can anybody chime in?

Would there be a problem with the tire guy putting run flats size 285 35 19 on the front nismo rims...I know in earlier posts it was mentione that it was tough to fit the 325 run flats on the rear so just wondering on run flats on the front nismo rims?

With front and rear camber arms it shouldn't be an issue. You should be able to adjust it if need be. I have no issues and I am lowered on coilovers.

Would the 285 35 19 work on a 19x9.5 +23 offset or would it poke out up front to much.

I have to ask- has anyone run this setup at the track? What did your lap times look like, in comparison to a previous setup? Wondering how that much more rotational mass impacts braking and cornering. It can't be good, can it?

First set up was 275/35-19 PSS on 19x9.5, and 325/30-19 PSS on 19x12 Forgeline rims. Alot more grip then stock. After the 325's worn out. I put 345/30-19 PSS on. You really have to push to get them to break loose. After the fronts worn out. I put 285/35-19 PS4S on. Ton of grip. You really have to be stupid to get into trouble.

That doesn't really answer the question, though. I'm more concerned about having a 325, with that much extra meat, on a 10.5" wheel, in the back. It's different having the 325 on a 12" wide back wheel, as it isn't nearly as whatever the opposite of stretched is. (LoL)

I guess I should clarify- it's not the fitment that is a concern, but more so, what is the performance aspect? Is it safe to do high speed cornering with 40mm more tire placed on the same wheel?

I'm not surprised about the increased tread life and increased grip- those do definitely make sense. But what about acceleration, braking, and handling feel? I'd imagine if you went back down in size, the car would feel faster and nimbler. So much more rotational mass to spin (aka kills power being put down to the wheels, etc).

It's kind of like my daily beater... a 2006 Acura TL 6MT. I use the oem wheels for winter use, and have bigger wheels/tires for summer use. After I pull the summers off in the fall, the car feels completely different. You don't nearly notice it as much when you put the beefier tires on... but you totally feel it when you take them off and replace with something smaller.

And final question regarding this setup...

So no spacers are required, if running the 285F and 325R, on Nismo wheels... if anything, maybe a 5mm spacer up front. Nothing for the rear.

For those on lowered suspension, do you have any rubbing issues whatsoever? Just making sure this is a smart setup for myself, as I plan on hitting the track and the last thing I want is to be worried about the tires constantly rubbing on something. My plan, at least for the time being, is simply going with Swift springs, and nothing else. Maybe coilovers in the future, but for now, just the springs.

Someone should update the original post.. OP made a bunch of assumptions when he decided to go this route... it would be cool to see a summary of the findings and answers to the assumptions originally made, without reading through 15 pages. It seems there isn't anything inherently overly negative about going this route, besides as I mentioned... slightly slower acceleration, less steering feel, and slightly slower braking... with the upside being longer tire life, good looks and better corner grip.

No, you will have no issues if you lower it down a bit. Just make sure you the adjustable arms to set the toe and camber when you do it.

True. My Z is set-up for the track. Alignment setting, sway bars, full SPL parts catalog, brake pads and rotors.

So u need a camber kit to run this set up lowered? I am on Swift lowering springs right now on a completely stock Nismo suspension. I have a friend who is on this set up on his Nismo but is at stock height with the OEM Nismo suspension.

Tires won't impact your camber. The lowering springs will. If you have no camber issues after putting the Swift springs on, you'll be fine.

I've heard the Swift springs are a modest enough drop that you don't necessarily need camber correction. Tire size shouldn't have much of an impact otherwise.

Ok, I'm having a bit of a wtf moment...

I decided to go with RE-11s in 285/35R19 for the front, and 325/30R19 for the rear, from Costco... but there's a bit of an issue: Costco tells me that Bridgestone discontinued the RE-11s!!!

Ok, I'll go with my plan "B" option: I'd go with the RE-71Rs instead... except they apparently don't come in a 325 size!!!

The only other tire Costco sells in that size is the RE-050, but I think that tire sucks balls... it doesn't even come close to the RE-11, or the slightly better RE-71R...

SO NOW WHAT DO I DO?!?!?
