Winter tire pressure in Colorado
−4 PSI
typical drop from July to January
The average temperature in Colorado goes from about 69 °F in July to 27 °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.

Is air free at gas stations in Colorado?
Only where the owner chooses. Colorado doesn't require free air, so many stations use coin or card machines that cost one to two dollars. Chains that give air away at most stores are your best bet, and some clerks switch a paid machine to free if you ask.
Which gas stations have free air in Colorado?
On our map, the chains with the most free or usually free air pumps in Colorado are Lowe's (29), Kum & Go (28), QuikTrip (25) and Costco (18). At franchised brands like Shell, BP or Exxon, it depends on the owner.
Where can I check my tire pressure for free in Colorado?
Tire shops are the easiest option: Discount Tire (60 locations) and Les Schwab (46 locations) check and fill tires for free during business hours, no purchase needed.
How much does tire pressure drop in winter in Colorado?
Colorado averages about 69 °F in July and 27 °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.
