Not so fun fact: your tires lose a little bit of pressure every day. Tires can lose 1 psi of inflation pressure per month under normal driving conditions. Additionally, tires can lose an additional 1 psi for every 10 degrees of ambient temperature change. Winter to Summer, you can expect the air pressure to go up with the change in seasonal temperatures. Summer to Winter, you can expect to see the air pressure drop with the decline in temperature. But keeping your tires filled properly makes for better handling and fuel efficiency, and helps your tires last.
You should check your tires every other time you fill up your tank. Look in your vehicle owner’s manual to find out what the pressure should be. You should also be able to find it on the tire placard on your driver’s door, doorpost, glove box door or fuel door. Of course, we want to make it easy for you, so you could just use the search below.
