I'm running 36 front (max recommended) and 40 rear on the street. Feel good. Watch tire pressure in cold weather, if the front is low, tire will flatten and be more prone to hydroplaning. I had to drop the front to around 29 to get any kind of grip when I was at Summit recently. My Q2's were much better than the 2CT's, and I only had to drop them to 32/32.
