No problem. Since the car was new to me, I did not push the handling much with the LS2. I had a bead fail on the LS2, so I didn't keep them long.
As for the feel of the AS3, I think the 550 feels plenty nimble and handles well (especially for a 4400lb + car). I've been very happy with the AS3.
I got mine from TireRack, had them mounted/balanced by the dealer (car was already there to see how much an LS2 costs)
I drove them in snow up to 6" with what you'd expect for results. It's not a jeep, after all, but xi still keeps things moving.
