Maybe the PSS since it has the square sidewall.
Speaking of PSS, has anyone fit them on the stock Rays yet in 305/30/19? I know the 305s work out fine for the RE11, but I think the PSS is a bit wider (tread width, anyways) with the square shoulder. I've seen it on Mustang/BMW but have yet to see it on a Z.

It's a huge pic so I didn't embed.
Edit: Scratch that. 305 PSS is definitely going to be too wide. 295 max with that tire on the 19x10. You can get away with a 305 on the RE11 but the PSS is just too wide.
