Winter tire pressure in Iowa
−5 PSI
typical drop from July to January
The average temperature in Iowa goes from about 74 °F in July to 21 °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.

Free air in Iowa: questions
Is air free at gas stations in Iowa?
Only where the owner chooses. Iowa 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 Iowa?
On our map, the chains with the most free or usually free air pumps in Iowa are Kwik Trip (160), Kum & Go (66), Hy-Vee (58) and QuikTrip (22). At franchised brands like Shell, BP or Exxon, it depends on the owner.
Where can I check my tire pressure for free in Iowa?
Tire shops are the easiest option: Discount Tire (18 locations) and Les Schwab (2 locations) check and fill tires for free during business hours, no purchase needed.
How much does tire pressure drop in winter in Iowa?
Iowa averages about 74 °F in July and 21 °F in January (NOAA, 2015–2024). At roughly 1 PSI per 10 °F, tires filled in summer lose about 5 PSI by midwinter, often enough to switch on the low-pressure warning. Top them up when the weather turns.
