Good tires are critical to the smooth operation of your vehicle. Keeping your tires in proper condition helps you save money and, of course, avoid major accidents. Understanding how temperature affects tires and their pressure is vital for car maintenance.

Importance of Proper Tire Care

Daily maintenance of your tires has long-lasting benefits for your car. Simple steps such as scheduled rotations and checking the rubber wear keep your tires going stronger longer. You'll also save money on fuel by checking your tires often. Riding on a damaged tire can lead to a sudden blowout in traffic.

Tire Pressure

Tire pressure is the amount of air in your tires. This is measured in pounds per square inch, or psi. The recommended pressure level is usually listed in the owner's manual.

Tire pressure is important because it will affect how well your car drives and stops. Too much air can cause you to have a rough ride while too little can cause tire overheating. Either of these can lead to a traffic accident.

Measuring your Tire Pressure

Check your tire pressure every two weeks or monthly at least. To get the best reading of your true tire pressure, take the measurement at the start of the day. After allowing your car to sit overnight, use a tire gauge to check the pressure. You'll an accurate tire pressure level when it is cold from inactivity.

Tire Temperature

Changes in the air temperature can affect your tire pressure. For every 10-degree change in the weather, your tires either gain or lose one pound of pressure. This makes it important to consistently check your levels because changes in the season will effect your pressure. A tire that is inflated just right at the start of August may become underinflated as the winter months begin.

How Tire Temperature Affects Its Pressure

The heat from friction created by the contact between your tires and the road will cause an increase in tire pressure. As the temperature of your tires rises, so will the pressure levels. This increase can cause overinflated tires to blow or underinflated tires to appear acceptable. Check your tire pressure often and stay with all regularly scheduled maintenance.
