Winter tire pressure in Idaho
−4 PSI
typical drop from July to January
The average temperature in Idaho goes from about 68 °F in July to 26 °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 31 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.

On our map, the chains with the most free or usually free air pumps in Idaho are Pilot and Flying J (8), Lowe's (8), Costco (7) and Kroger (1). At franchised brands like Shell, BP or Exxon, it depends on the owner.
Where can I check my tire pressure for free in Idaho?
Tire shops are the easiest option: Les Schwab (60 locations) and Discount Tire (8 locations) check and fill tires for free during business hours, no purchase needed.

Idaho averages about 68 °F in July and 26 °F in January (NOAA, 2015–2024). At roughly 1 PSI per 10 °F, tires filled in summer lose about 4 PSI by midwinter, often enough to switch on the low-pressure warning. Top them up when the weather turns.
