A couple disparate points:
1) I live at the end of nearly four miles of dirt/mud/slush/snow/ice out in the country, making RWD less practical for me.
2) An AWD vehicle is quite capable of pushing to the tire's limits. However, that was never my point. My point was to further enhance the performance of the vehicle I have, and summer tires will aid that cause. Higher performance tires increase braking potential, cornering potential, and acceleration potential (enlarging the traction circle), regardless of the particular drivetrain.
I would have preferred that my vehicle came with summer tires, but it's much easier to change the tires than the drivetrain. Actually, I would have preferred my vehicle come with WINTER tires on the stocker 18" wheels, and I would get my own 18's or 19's in the size and configuration I want, shod with good performance tires.
