Anyone running 255/35-20's?

[Cogitoergozoom]

I have a 2008 Altima 3.5SE sedan with a stock ride height and plan to use 255/35-20 tires. Is anyone using that size a tire and are there any rubbing issues? The rims are 20x8.5 with a +35 offset so they are pretty much flush with the outside edge of the fender which worries me some.

Ive seen 245's used but the sidewall just seems to thin to me. Plus I want to prevent rim dings as much as possible.
