Checking Tire Inflation In The Cold

Checking tire pressure in cold weather is the same as in the heat, but is increasingly important, as inflation tends to drop with temperatures. Here are five simple steps to checking tire pressure:

  1. Make sure your tires are cold and haven't been driven in several hours1
  2. Check manufacturer's recommended tire pressure on the door placard
  3. Record the PSI for each tire
  4. Check tire pressure with an accurate guage
  5. Fill to recommended PSI

How Cold Can Affect Tire Pressure

For every 10 degrees of temperature drop, tires will drop 1-2 pounds of pressure. It is important to keep your tires within the recommended PSI to maintain traction, handling and durability.

How Heat Can Affect Tire Pressure

Just as colder weather can cause PSI to drop, excessive heat can cause your tire pressure to temporarily increase. For every 10 degrees of increased temperature, your tires can be expected to increase by 1-2 pounds of pressure.
