Unofficial Big-Wheel Thread: 18/18 and 18/19 - the future for NSX tire sizes

I'm pretty sure that was not a 225/40-18. I'm not sure why you're so adamant on pushing useless tire sizing on a thread that's performance oriented. We already discussed all of this on the other thread and here was my reply:

What tires is that car running? Like track widths, sidewalls vary from brand to brand and tire model to tire model. After looking at various 275/35-19 setups on a 19x10 (including my M3) they do not bulge as much as that car.

There is a lot wrong with the picture of the red car which makes it not a very good example. Its on uneven pavement which visually makes the front ride height even worse, the front tire is not properly balanced with a 225/40-18, the front and rear ride heights are off (needs coilovers), and is pre-02 bodywork which visually makes the car look higher.

Here's some 275/35-19 that looks a lot better:

The T1R is okay for the street but it's not a very good track tire.

I'm pretty familiar with tracking NSXs, knowing how 'sensitive' they are to any tire size changes, the importance of balance, and fitting wide (345) tires on them :wink:


I suck at photoshop, and the car still does not have the 02 bodywork on it, but here's a vague idea:

That 100% is NOT 225/45-18.

215/35-18 specs are as follows:

23.9" Diameter

8.46 Width

2.96 Sidewall


225/45-18:

26.0" Diameter

8.86" Width

3.99" Sidewall

I will just about guarantee there is no possible way to fit a 26" Diameter tire on the fronts of our cars... unless you possibly plan on RAISING the right height.

Ok well you just updated your post to now say 225/40-18 as I replied before it listed edited, which was originally posted as 225/45-18

There is a very simple response to this... forcing oversize 18/19" tires on the NSX is not the answer to drying up 17/18" performance tires you prefer. Once again... I'll wait for pictures justifying this will work and or be functionable with any lowered or aftermarket suspension.

IF you are that insistent on running huge 18/19" tires... Widebody fenders all around may allow the fitment of these.
 
Yes I had a typo in post #49 which I fixed. The plan is to make a 225/40-18 and corresponding rear fit due to the tire choices. I'll repeat. If you're in Ken (and now Chris') camp of the easily fit but severely limited 'ideal' sizes. This thread is not for you. If swapping to wider front fenders to allow the best tires on the market to be used on your nsx, please post.

Wow Billy... this has gone too far. To now put me in Ken's camp is a low blow. LOL

Anyway... Since I am currently waiting for 2 18" Advan Model 5's to arrive for my 17/18" Beefy track setup, what do you have against the 17/18 Toyo R888 sizes available?
 
You were using his repetitive hammering of new ideas and directions and acting stuck in your ways like him ;)

17/18 is a better track package but they don't offer Hankook TDs in 17". I'd probably go with an NT01.

I plan on back to backing 17/18 and 18/19 on track with data and the same model tires to know for sure.
 
Are you guys talking about the infamous Ken Sax?

Interesting that these guys have our beloved 235/40/17... They contacted me wanting to try the 17/18 setup on my car. I'll report back with any comments.

Sweet. Interested to see the data. I've always preferred handing on 18/19 compared to same tire brand on 17/18.

Now for my 17/18 setup for all the other trackies in here... Toyo R888, Falken Azenis RT615, or Nitto NT01?
 
Of those 3, nt01 hands down. I'm not sure why the 888s are still talked about but that's just me...

The 615k doesn't belong in this grouping. Chris, you do realize if you put on a track setup you'll actually have to track your car right? Haha

NT01. What tire (model) and sizes (widths) in 17/18 and 18/19 have you tried and what about the handling on the 18/19 do u like more?

Yes Regan LOL. I have tracked my car many times years ago... haven't in the past few years due to work and really not being able to miss time while the market is open. Most track days up our way are weekdays... Limerock in specific is about 30 minutes from my shop and are closed Sundays due to noise restrictions. I think you forget I have owned my NSX 12 years now. I brought up the 888's because I like the tread pattern... some people seem to love them.

I can probably go on for an hour or two about different wheel setups I've ran. I literally have probably had 70 wheel setups on my car over the years. From 16/17... 17/17... 17/18... 18/18... 18/19 etc etc. I've ran many many different tires and sizes as well. Nitto's, Falkens, Goodyear, Bridgestone, Michelin, Hankook, Yokohama. In a wide range of "normal sizes" as suggested, and over-the top pushing to the limit sizing as well. My liners are removed etc. For me, the car feels lighter and more agile on 17/18... but on 18/19 feels to have much less sidewall flex. (and there is a possibility that is just in my head)
 
Why hasn't anyone mentioned 215/40/18 fronts and 275/35/19 rears? Seems like a good setup to me for the people wanting a little more sidewall.
 
So 215/40/18 will rub in front on a 18x8 wheel? That is the only proper tire size "looks wise" that I think will work with a 275/35/19 rear on a 19x9.5 wheel!! I am actually looking to order this exact setup for my '91 NSX with stock fenders and liners intact. I found a sweet deal on a set of TSW Carthage wheels with +40 offsets. Let me know what you guys think. I'm looking to keep some sidewall...
 
I'd do 18x8.5 for a 225/40-18 and 235/40-18. A 18x8 would be fine for a 215/40-18 but if you can find a +42-45 offset it would be better otherwise you need to max your front camber.

All the above will look good with a 275/35-19 rear tire and be fine for TCS and abs. However I'd prefer a 19x10 rear +35 to +45.

smartest thing youve said yet to answer some doubters I think it would be fair to say that you testing back to back would make us all pay more attention to the results of this theory
 
I found the perfect widebody street setup. Pirelli makes the Pzero in 245/35zr18 front that is only 24.1" in diameter instead of the 25.1" diameter of most tires this size. That keeps the overall diameter similar to stock, you can run this on a 9" front, we will be running it on a 9.5 for our SV28 Widebody. Combine this with 285/30 or 295/30 on an 11" rear, perfection for a widebody NSX. I don't think anyone has ever ran this combo so I am excited to try it out. For track we will go 18/18 though.
 
Mmmm, new tires are here care of Pirelli North America. P zero's in 245/35zr18 and 285/30r19 for the new SV28 Widebody kit, can't wait to get these mounted up! Gotta finish the new wheels first.

Here's my setup! Picture is where I just got my front Stoptech trophy kit!
18x8 +37 19x10×35
Looks good. What tires/sizes are you running and any more pics outside?

Thats another great option for staying closer to the OEM sizes, but it has a very thin sidewall and only has about the same amount of offerings as the current 17/18 setup.

Here are a couple more tires for those sizes:

Continental's ExtremeContact DW - 245/35-18 with either a 265/30-19 or 275/30-19 rear

and one of the best tires on the market:

Michelin Pilot SuperSport - 245/35-18 with either a 265/30-19, 275/30-19, or 295/30-19 rear

.

I don't think those 245/35/18 front will work even on wide body. When you turn the wheels they will hit the headlight buckets even with the liners removed. Even wide bodies will be limited by overall diameter not just if the wheel will fit width wise! But gt theory said he chose those based on overall diameter so let's see how that plays out, I hope it works!

The Pzero definately have a small sidewall. There is a pretty wide variety of 245/35r18, however they all run 24.8" or larger. The Pzero is only 24.1, which I'm hoping will eliminate rubbing at full lock. The Pilot sport 225/40 rubs on a 18x9 et 30 front if you are low unless you trim the seam at the back of the front fender.
