Winter tire pressure in New Hampshire
−5 PSI
typical drop from July to January
The average temperature in New Hampshire goes from about 69 °F in July to 22 °F in January. Tire pressure falls roughly 1 PSI for every 10 °F, so a tire set to 35 PSI on a summer afternoon reads about 30 PSI on an average winter morning.
Most tire pressure warning lights switch on when a tire is about 25 % below its recommended pressure. A cold front plus a slow leak gets there fast, so check your tires as soon as the first cold mornings arrive.
