Shouldn't have TCS issues if he's running a 275/30-19 rear.

- 18/18 18/19 big wheels
I'm waiting on a set of 18/19s myself. On the order list are Michelin Pilot Super Sports per recommendation from [MENTION=16531]stuntman[/MENTION] and [MENTION=16745]Nero Tenebre[/MENTION]
225/35-18 front, on a 7.5" width wheel (Does anyone have any experience with how this 225 fits on a 7.5" wheel?)
265/30-19 rear, on a 9.5" width wheel
My price on the 225 PSS fronts are $255 for each tire installed. The 265 PSS rears are $225 each installed. The 275 rears are ~$320 each. It's totally not worth the near $100 per tire price increase for the 275s. What kind of pricing do you guys see?
@jones83 - yes it's 18s all around I believe? It's on their build website I read somewhere in passing.

Thanks for the reminder [MENTION=16531]stuntman[/MENTION]
I might be a little screwed here but let me know your thoughts. I think I might be within the realm of acceptability (I hope!) in terms of tread width vs wheel width.
Tire Rack has the 225/35-18 tire width at 8.2". My front set wheel width is 7.5". When I initially purchased these wheels I thought that since the wheel width is measured at the bead and not at the out lips, the 0.7" variance would equate to 0.35" bulge on each side. I thought that the 0.35" could be easily compensated by the lip section of the wheel and would still result in a somewhat perfect fitment or a very mild stretch of the tire. I hope i'm making sense here.
After reading this again... I might be wrong? Notice in your graphic below your min recommended wheel width is no smaller than the tread width. For example, a 255/35-19 PSS has a tread width of 8.5". The min wheel you recommend is 8.5".
Any thoughts? Are you taking into account the width of the bead vs the tread width?

Secondly... if I am screwed and should have bought a 8" wheel, will the 0.35" increase in bulge have severe adverse affects in sloppy handling, as you mentioned in the article?
I just have no experience with this amount of tire sizing nuance.
that's a great article,billy,and it really changed the way I think about tire sizing. Highly recommended,regan
Another update.. The closest visual confirmation I found is with the M3 guys.
This is a 225/45/17 with the same 8.2" tread width on a 7.5" wheel. Granted this is a 17" with taller sidewall.

My "recommendation" -which is quoted in red in the article , is based off of my experiences and thus takes in to account the width of the lip.
I had an e36 m3 with that tire size. You CAN run it, but of course the steering response and performance would be better on a 8-8.5" wheel. Since you have the 7.5, going with that tire size is probably a better compromise than a narrower, lesser tire.

Nice to see the PS Cup2 fronts appear in 225-40. I am another one working toward the "big tire mod" and accompanying ride height & fender liner mods/deletes. I will try for 2 or 2.5deg neg camber in front, or more even.
Funny though I might end up doing all that for RS3s, which I have always loved at least the version 1. The problem for me is these mediocre Pirelli Zero Nero GTs (225-35 & 275-30) are just lasting too long..:smile:
My wheel specs are:
BC Forged RS41 Monoblocks. 18x8.5" +44, 19x9.5" +35 (18.1lb/21.7lb).

Ryu, how are the pss working for you in a 225 size? I am thinking of pulling the trigger on these in a 225/35/18 and 265/30/19 to wrap my rg3 18x8 19x10 is the front too wide? The width on the 225 is n/a on all spec sheets for this tire?Thanks for the reminder @stuntman

[MENTION=31260]Jinks[/MENTION] are you on Facebook? [MENTION=14678]TURBO2GO[/MENTION] and I were just discussing this. He or I can tag you
Unfortunately I'm running on DF wider fenders so I don't have a frame of reference to compare for you. It's probably fine if I was to bet money...
How's the handling and ride quality?
I love it. Probably the best all around sporty tire i've been on in a long time, maybe ever. There's virtually zero compromises. When I leave for an early morning canyon run, the roads are sometimes wet/damp, muddy, dusty/dry. In 25 miles i'll go from 0ft elevation to 3500ft where in the shadow is icy/wet and in the sun it's warm. I've never been on a more consistent tire with such a wide range of "sweet spot". Obviously, it is not as sticky as a R-Comp. It might not even be as sticky as the cheater street R-comps but the tire communicates very well. I especially like how it's more communicative at more aggressive slip angles. It doesn't fall off so quickly in that perspective. My car tends to be more understeery so it's nice to feel that thru the steering wheel.
It's quiet. It's comfortable. It doesn't like to handle too much heat from the last time I was at the track with them. I wouldn't use them as a dedicated track set which is fine by me.
The parts that sucks is the increase NVH as transmitted via the very thing 35 series sidewall. I don't think that's the fault of the tire. Its just the sizing. Unfortunately they don't make 17" PSS's in appropriate NSX friendly sizes.
Doesn't belong in this thread but Z2* or AD08R are good tires.
BTW.. I can't comment on TCS issues with my PSS sizing. I yanked that POS TCS module a couple of years ago.
Talk about top 5 things I hate about my NSX.
#1 is that crappy TCS module.

Sorry I'm still new to the forum. Thanks for replaying but these are not available in my country and shipping will cost twice the price of the tires them self.
What country? What tires are available?

Oman. Check my thread in new owners "z4m vs nsx"
i found only nexxen korean and some other chinese brands. Front and rear unmatched as well.
Well, I finally did it, I got the Pilot Sport Cup 2s installed in 225/40-18 and 275/35-19. :smile:
I ordered my wheels with these tire sizes in mind from reading Billy and other helpful people in this thread. And I am happy with the fit on 18x8.5" +44 and 19x9.5" +35-- I don't reckon I'd change anything if I did it again, and no spacers are needed.
I will post pics after I monkey around with it some more and get the ride height sorted out. So far I have only done 200mi on the highway so I can't report much. I did a camber kit for -3* up front, no fender liners or AC shrouds, some work pounding the pinch weld back, and stock fenders. The rears still have liners.
Meanwhile I'm thinking the Clarion car deserves to be in this thread since it was the first with PS Cup2s.
They are 225/40-18 265/30-19.
And the specs for those wheels are: Volks ZE40 18"x9"+34mm and 19"x9"+33mm. It has DF fenders.

......be careful without a front liner and sticky rubber...I got a reverse ding with track tires and no liners
225/35-18 definitely makes more sense and is what I had up until now in a crappy Pirelli Zero Nero GT. You can get that size in a PIlot Super Sport -- much less hassle than my PS Cup2s and better for normal people who aren't going to modify their car to fit big tires.
Bummer to hear that Doc. [emoji22]I am using a spray-on liner to protect my fenders.
