Winter tire pressure in Tennessee
−4 PSI
typical drop from July to January
The average temperature in Tennessee goes from about 78 °F in July to 39 °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.

Free air in Tennessee: questions
Is air free at gas stations in Tennessee?
Only where the owner chooses. Tennessee 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 Tennessee?
On our map, the chains with the most free or usually free air pumps in Tennessee are Kroger (82), Lowe's (63), Pilot and Flying J (37) and QuikTrip (11). At franchised brands like Shell, BP or Exxon, it depends on the owner.
Where can I check my tire pressure for free in Tennessee?
Tire shops are the easiest option: Discount Tire (30 locations) check and fill tires for free during business hours, no purchase needed.
How much does tire pressure drop in winter in Tennessee?
Tennessee averages about 78 °F in July and 39 °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.
