Tire size to prevent TCS problems

Hey guys,

I'm in the market for a new set of rubbers (no flames) and I already had in mind what to get:

225/35/17 front

285/30/18 rear

I currently have HREs at 17x7.5 front and 18x10 in the rear (I believe). I went to Tirerack.com to make my order however I notice that there are no tire profile sizes less that 40 series. I currently run 225/40/17 in the front and 285/30/18 rear. I have problems with rubbing and I cannot use my TCS (it activates alot during acceleration)

I was wondering what other sizes you guys with 17/18 rims are running with the SO-3s. I love the Bridgestones and would rather not go to another brand. I did a search to see what I could find with little luck.

I know there is a NSXprime member that is also part of Tirerack.com; If at all possible, could you offer some advice.

Thanks guys

I think the 225's in front will look too thick on a 7.5 inch wide wheel. My personal opinon would be to go with a 215 in the front. Plus that will reduce rubbing if your car is lowered.

Hey Kevin,

You will need: Fronts 215/40/17 Rears 265/35/18.

I have no problems with the TCS light!

I recommend the same thing. The S-03 comes in those sizes, and they should not activate TCS.

Thanks guys,

I am curious though, would those sizes still give my tire wall that flat, flushed, look with the rims?

Do we get disounts for being NSXCA members through Tirerack.com?

I wanna get the order out of the way ASAP.

Thanks once again.

BTW, NSX FoYoAss, my car is lowered. I am wondering if you use the same tire sizes for your car. If that avatar is your car, it seems to fit nicely.

Give Ben a call at Wheels Boutique. He knows his stuff and I am sure he can get you the best price in town for tires 786-249-0127

I actually have 18x8's(with 225/35/18) in front and 19x10's(with 275/30/19) in the rear. I wish I had gone with 215/35/18's for the front tires because of rubbing issues. My car is dropped 2inches.

Tires tend to look flat and flushed when the wheel width is in the middle of the approved range for that size tire. (If they are at the low end of the range, the tires tend to look like they bulge out; at the high end, they tend to look stretched onto the rim.)

Checking Bridgestone's specs for the S-03, the approved rim width for the 215/40-17 is 7.0-8.0 inches, and for the 265/35-18 is 9.0-10.5 inches. So yes, they should look just fine on your 17x7.5 and 18x10 wheels.

No. Neither the Tire Rack nor Discount Tire Direct currently gives any discounts to members of any car clubs. Prices at both places are generally pretty darn low, though. As always, your best bet is to shop around and compare prices.

Wow NSX FoYoAss your car is slammed.

Armando, I was actually talking with Julian earlier and he mentioned the same thing. I believe his avatar is THE WB. I will try to get in contact with him (his shop is called Wheel Boutique?) to see what deals he can offer me.

Thanks guys

as always, Thanks Ken

Looks like it will be 215/40 and 265/18

Appreciate the help/

Did anyone bother checking the Revs Per Mile quoted on the Bridgestone page against a tire calculator?

For the 215/40-17 they print 875 revs/mile
For the 265/35/18 they print 820 revs/mile

Maybe their test track is covered in Astroglide beacuse the correct numbers are 848 and 797 respectively, which yield a slightly higher percentage difference than the printed numbers do.
They are still well within the 5% differential when compared to a 93 NSX with OEM tires.

Someone please double check my findings.

The actual size of tires varies greatly between manufactures.

I have measured, side by side, two mounted tires in 225/35-18. The S-03 was 1/2 inch shorter in diameter and had 3/4 inch wider tread width than the Toyo T1-S.

Bizarre.

Silly me was under the impression was that these standards were put in place for uniformity amongst the manufacturers. I mean it's really pretty simple isn't it? Centimeters are centimeters, percentages (aspect ratios) are percentages so why does it not compute Will Robinson?

Yeah, it seems like they make the tire and then classify it to the closest size rather than engineer it with a size parameter in mind.
