My owner's manual says that "snow tires" should be inflated 4.3 psi higher than what's stated on the tire pressure label. Why would that be? As I understand it, when the air temp decreases 10 degrees, the tire pressure decreases about 1 psi. So does the manual assume that we'll be measuring the tire pressure in a garage that's 40 degrees warmer than the outside temp? That seems pretty extreme.
Anybody have another explanation?
