Rickd, I respectfully disagree with your claim. Lower tire pressure offers less unit pressure contact with the road due to increased surface contact patch area. The tread does pump some water but weight per unit area keeps the rubber on the road. Lowered pressure is dangerous in rain, tag along with a crash forensics unit.. Among the first things they record is tire type, condition, pressure and skid mark width (if any).
As for cold temps, I raise a few pounds since my warm target pressure is the same year round which is about 42-43 fully warm front and 47-48 rear. After experimenting I found that adding about 2 pounds when temps drop under 45F results in about the right pressure. In cold weather there is more delta T i.e., tire pressure rise is less than in warm weather.
As mentioned earlier by another member, the tire pressure label is there to placate lawyers. Ideal tire pressure varies with use and temperature and the label is a safe one size fits all general use thang. Track pressures are much lower due to differing friction and compliance requirements along with significantly higher temps due to both low cold pressure and more knee dragging in corners. Naw, aint used pucks before on the K like the mad Dane.
