How Cold Weather Affects Tire Inflation
As temperatures get colder, drivers may notice an impact to their tire pressure, and their TPMS light may be illuminated on the dashboard. This happens naturally and does not necessarily mean your tires are leaking. Learn about how weather impacts tire pressure below.
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:
- Make sure your tires are cold and haven’t been driven in several hours
- Check manufacturer’s recommended tire pressure on the door placard
- Record the PSI for each tire
- Check tire pressure with an accurate gauge
- 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.
