You seem to really know your stuff so what pilot 4s tire size do you recommend for a street driven car stock suspension stock sport rims.

I know enough to be dangerous lol. I would suggest staying with oem sizing and getting Swift springs for a little drop and better ride. I would also recommend 20mm spacer to make the wheels and tires flush and not be so sunken.

Lol I feel that. I'll stay with OEM size and get some springs and spacers. Then I'll eventually get a proper suspension setup and some new rims for the next set of tires. Would 20mm spacers be for all around front and rear?

Hey guys, thanks for all the recommendations!

Just to be clear this is more of a daily street car with the occasional track day. I got the wheels as an open box deal hence scooping them up first before figuring out the exact tires etc and yeah, already got all the necessary suspension upgrades. Also have 20mm spacers and even a set of Moonbeam fender flares to got with it all!

Currently working on installing everything but just wanted to see what people thought of the tire sizes.

Sounds like 265/40 and 295/35 is the way to go for street, would love to go wider with the 275/35 and 315/30 Toyos or BFGs but it's not a track specific car and I don't want to get screwed if I get caught in the rain..

um, those sizes aren't gonna work for overfenders man

You didn't list offsets (...?) but the MOST AGGRESSIVE spec for GTC01RR is 18x10 +22 and 18x11 +16

those aren't even the limit of STOCK fenders, and then you're gonna be slapping on widebody?

It's gonna be sunken as hell

Yes, the offsets are the most aggressive ones you mentioned and they're both rear face. I also have AP racing calipers front and rear so 20mm spacers were needed for the front to clear them. The moonbeam fenders really aren't so widebody, they're actually pretty shallow for flares. Already did the test fit and they look pretty good!

Seems like waste of money and effort to cut, paint and install fenders for no gain...but it’s your car, whatever

Well that's the fun thing about looking at numbers on the internet vs looking at things in real life. When I said 'the fitment looks good!' it's because I was there :D

OZ - Just let him do his thing. Carbon Signal recommended a 20x10 -15 and a 20x11 -20 but hey, what do they know... He seems to be setting himself up for success. :rofl2:

I live in NYC/NJ area where we have this thing called winter that produces these things called pot holes. Some of which are massive and on the off chance I hit one, I don't want the tire to smash into the fender. So flushness isn't the priority. The way it sat when I tested it was just on the inside of the flare which is exactly what I wanted. All I came here for was to ask about best tire choices..

it's your money, do whatever you want

if functionality is the issue, get a cup kit or air instead of cutting/painting/riveting on fender flares that don't fit your wheels

but again its your money, set it on fire, put it in a hole in your back yard, spend it on flares, be happy

I don't understand.

Why run flares if you aren't going to fill out your wheel wells?

Ahhh yes, the majestic, elusive pothole that only areas that snow seem to have...

Anyway to cut the sarcasm short, "flushness" won't result in your wheel/tire slamming into your fender, bad fitment and suspension setup will. My setup is flush, with a decent tire, and I have no rubbing/etc. but no clue what I'm talking about either so enough about me.

To answer your Q: if you plan on going with the 18x10/11 GTC combo I would have originally suggested a 275/40 and 305/35 combo... however, since you don't want to listen to advice and want to run oversized flares on an undersized offset (including the spacers), I'd recommend you get the largest, widest tire you can fit on a 10"/11" wheel. So, something along the lines of a 305/35 in front and a 335/30 in the rear.

Now that's meaty. :yum:

Plenty of folks are running as aggressive or more aggressive wheels without needing fender flares

hell, like Hotrod said, he's running a goddamn 315 in FRONT and he TRACKS the car without issues

I've read so much my eyes are crossed... I've found several posts that kinda fit my car/application but not exact, so I'm just gonna ask....

I have new 18x10.5 +15 rear and 18x9.5 +22 front wheels (uninstalled). I need tires for them.

Im lowered on Swift R, have spl rear camber arms/toe bolts, front is stock camber arms. I'm looking to put either 255/45 285/40 f/r or 265/40 295/40 f/r if possible. I dont care to get the car realigned, but am worried about front rubbing issues and for now, not having to install front adjustable camber arms.

What do you think? Will it rub under spirited driving / autocross conditions?

Other options are welcome, but I'd like to keep the stock tire ratio close. Thank you.

Dunno. What size wheels are you running now?
I dont know what your fitment is currently like or what your ride height currently is.
I would guess no - as most springs don't take you anywhere near low enough to rub but again, that is a guess.

Sorry, shoulda said that.... im on base 18" rims. 225/50f 245/45r with 20mm/25mm spacers f/r. I'll be removing the spacers totally, but everything is aligned currently with -1.8 f camber and -2.1 r camber at the moment.

Im basically worried about the front rub under hard braking or big bumps during spirited driving (autocross).

Thanks

Hey guys, need help. Currently running 275/35 on stock Ray's. But since the wheels are staggered, people are making it sound like it's a problem to run square on staggered rims. What if I do 265/35 front and 275/35 rear? What's a good combo? I want to keep my front 275s since they are brand new lol

They’ll filt on the 9” front & you’ll have a slight rake...but they’ll bulge some vs the rears :ugh2:

What brand/model are your new 275’s ?

Federal Rvoluzion ST-1 I heard federal run slightly wider.

I thought it would do that too. 265 up front would bulge too?

Never heard of them :ugh2:
I’ve ran Michelin,Goodyear,Nitto,Yokohama.....but I’m not seeing those except on eBay :confused:
It’s your Z, they should fit...but unsure what they’ll look like.
:rolleyes:

hey guys, so in the meanwhile trying to figure out what i can fit

fenders are rolled in the front and fender liners are cut in the front and rear by the pro tony

so now

planning to run -3.2 camber in the front and -3.6 in the rear

specs are

19 x 10 et 11

19 x 11 et -3

want to run toyo R888R

275/35/19 and 325/30/19

tucking .2 inches of tire

Why a 325 in the rear?
305/30 within spec and will fit more easily

I just feel like the 325 will look more proper, but im open to the 305. just thought we have so much room back there, why not?

You can check this your self:
https://www.toyotires.com/tire/patte...s-proxes-r888r

the 275/35 is square on a 9.5 inch rim. Slight stretch on a 10
the 305/30 is square on an 11 inch rim
the 325/30 is square on an 11.5 inch rim. Slight bulge on an a11

The 305 will fit with less camber required

325’s in the PSS’s are bulged a bit on the 11’s & a 295/30 would be slightly bulged on the 10 up front.
I have both tire sizes here & diameter differential mounted is only 0.4” (26.15/26.55)
My 325’s are measured mounted on a 12” wide wheel though,with an ever so slight stretch :ugh2:
275/325 stagger needs a 2” wheel width stagger to look evenly...Tire mfg will make a difference as well :tiphat:

ok i think this is what i'm going to do unless I can squeeze what jchammond recommended

hmmmm im really tempted to go that wide, you think i can fit with those wheel specs?

i'd just go 365/35 and 305/30. Matched diameter, even fit on wheel, easy fit under fenders. note that R888R runs wide compared to other brands

although i gotta ask

is this a track car? Because R888R's are not exactly daily driver tires

if it's a track car, most would suggest less stagger, more tire up front. But you have a staggered rim width which makes that harder

I don't think anyone needs a 325 in the rear unless they're running boost

Track people are running 275 or 285 square; hot rod is on the high end with a 315 square

If this a street car, the R888R's are complete over kill

On some expensive works . . . i would not bring those to the track unless you are a total G that can afford to damage one and replace it. Otherwise, thats a $1,000 wheel put a risk

be smart

Throw on some streetable tires for these

and if you are gonna track, grab some 18x11's or 18x10.5 square and have fun

I would not bring my TE37 Ultras to the track because i'm not made of money

Actually it isnt a track car, Just a fun weekend car. I drive under 3k miles a year. Strictly runs and canyon runs

I want to go aggressive with the set up and I feel like 265 isnt enough on a 10" wheel. i had 275/35s on my advans up front and I felt like that was the complete right amount of tire for the front. Thats why I feel like Im going with the 275 305 combo. Do you recommend any good high performance tires. I always tend to over kill, especially with KW V3 and works
Im learning to tone it down

I'm getting it ready for the track and I will have a pair of Work MCO's for the track/when I dont have the meisters on. In contact with FI for an oilcooler and such

for sure want to do my first track day by the end of this year

oh and I just got an evo r high wing for the down force ya know..... lmaoo

the 10 inch / 11 inch stagger puts you in between some sizes

but i know people that swear by the RE-71R from Bridgestone

the Bridgestone S04 and Kumho EVO2 V212 are less aggressive performance tires that won't get burnt up quick

265/35 front and 305/30 rear will make your life easier
height and camber can get you the look you want

i am running the Toyo T1R because there weren't that many tires that came in 275/30/20 and 315/35/20

true

I still have some time before the wheels get here, so im just weighing my options

even thought of pilot sport cup 2's 285/35 and 315/30

I want a slight buldge

are you even looking at the tire specs?

Cup 2's are a 180 tread wear tire. They're uber aggressive

tires are a wear item

if you got the cash to burn through those just to drive fast in a canyon every once in a while, i salute you

Cup 2's are short lived. Less than 5,000 miles out of them.

Slight bulge isn’t bad on the straight runs; the canyon carving will perform better with a square or slightly stretched setup,,,sometimes 1” staggered wheels will handcuff you between sizes....meaning you could end up with a stretch/bulge setup :icon14:

A couple pics of the slight bulge of the 295/30/19 on a 10” wheel vs a 325/30/19 on a 12” in Michelin.
Unsure about any contact underneath fenders with your wheel specs.....https://uploads.tapatalk-cdn.com/202...8fc2abdb59.jpghttps://uploads.tapatalk-cdn.com/202...395d83d412.jpghttps://uploads.tapatalk-cdn.com/202...f8292c9687.jpghttps://uploads.tapatalk-cdn.com/202...262b06d066.jpg
Try to avoid headaches if possible; camber specs you posted up are definitely for camber carving & a slight stretch will outperform the slight bulge.
MFG stretches tires/wheels from factory on these cars.

:iagree:
R888’s in 265/35,305/30’s would probably give you the best chance to fit without rubbing & only slightly stretched up front :ugh2:
Unsure how spot on their diameter of tires are...but the Michelin’s I have are different diameter specs than what website says.
If you have someone who’s willing to mount/dismount tires without dinking up your wheels & test fitting before purchase....go for it :tup:
Unless you have been plucking HotRodz money tree :icon17:
