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:
