Although i sure am curious what actual height is on the 305/40/17 which is supposed to be a 27.5" tire,

I would consider running this rear wheel / tire combo on my A6GS but I am concerned the 25.5" diameter compared to the stock 325/30/19 26.7" when paired with the stock fronts 275/35/18 25.6" will set off AH/TC hell.

I have a 2012 GS with a 6L80E and my tire is the M&H 325/45/17. I have been a best of 1.27 60FT with that tire. My performance shop told me that I had to run a 28 inch tall tire.
