I’ve had Bridgestone RE760 (UHP summer) and Conti DW (max performance summer) on the GTI so far, and both seemed to have more dry grip than the A/S 3+. We generally don’t get a lot of rain here, so I never gave much thought to the rain performance of those tires, but the A/S 3+ does seem to be pretty darned good in the rain.
I bought the A/S 3+ because we can get snow and cooler temps in May/June and Sept/Oct. Figured that with the all seasons, maybe I could put them on a few weeks earlier in the spring and take them off a few weeks later in the fall.
