I put 2500 miles on my new GSD3s over the past five days, running in the rain, heavy at times, and some dry. Very responsive, better in the wet than the originals, but also slightly more wander than the originals (this may also be due to the alignment the dealer did as part of the warranty work, but I don't think they touched the front end, just the rear settings which were pretty far out on the right side. They also wanted me to inflate them at 35 psi when cold, and although I was wondering about the ride it was great. I did have a load, 4 full sized adults and 200 lbs of luggage but averaged 23.5 mpg for that distance with average mph of 67 (most highway miles at around 78). All in all, very pleased.
