My first set of tires was Hankook RS-4 in 245/40/18 and 275/40/18 - 10mm wider f/r but also a little taller and I think that hurt my gearing a little pulling out of corners.

Now I am on 245/40/18 and 285/35/18 R-S4, and the slightly shorter sidewall on the 285 has helped my gearing and pull out of corners, but I am still not running out of gear in places like T13 Tower turn at Sebring where I wind out in 3rd. And I can really tell the extra difference in that extra 10mm per side back there, I can really press hard and the car really sticks back there. I am now battling a little understeer in front, so I wanted to try 255/35/18 in front, but oddly, according to several folks at Tire rack, the 255/35/18 R-S4 is actually not as wide with regard to tread width as the 245/40/18 so I am sticking with the 245 until I can lay eyes on a 255 tire in person to see for myself.

In the NT-01, I think 275/40/18 and 245/40/18 would be just right. That should fit on the OEM wheels if that's what you are running.

I think you will feel this, I sure did but with all your extra "S" power for your next set, I think going 275/40/18, the extra width and grip will offset the gearing loss.
