All Terrain for the Acadia

[PirelliSteve]

Hello there Acadia owners. I'm the US product manager for Pirelli Tires and am wondering what you all think about All Terrain tires. There aren't any on the market in you major sizes right now, 255/65R18, 255/60R19 or 255/55R20.

I'm thinking about adding your three sizes to our Scorpion ATR, a highway optimized (low noise) all-terrain tire. Any feedback would be appreciated.
