Stock Michelin PS2 tires do well in 37 degree weather with rain.
As unpredictable as the MD/DC/VA area's weather is, I had my summer tires on thinking spring was here. Temps dipped into the 30's tonight, and it started to rain. I was pretty impressed with how the PS2's handled it. Never felt like the car was on edge. Can't wait to try the PSS's.
