What is the right tire pressure for my car?

During intense summer heat, tire pressure may fluctuate and lead to premature wear. If your tire pressure is low, it may be a surface-level issue. Check for punctures on the tire surface and make sure air isn’t escaping. Many newer vehicles (late 2000s and on) have a TPMS or Tire Pressure Monitoring System that will monitor tire pressure. This sensor will wear with the car’s battery and can malfunction as the battery reaches the end of its life. Other faulty sensors, like the ABS (Antilock Braking System), may also contribute to indicating low tire pressure.

The recommended tire pressure for your vehicle depends on manufacturer recommendations, as well as tire size. You can find this in the owner’s manual, usually located in the passenger-side glove box. The sticker found on the driver’s side will also list factory recommendations for standard tires. Newer vehicles will display tire pressure for you on their dashboard screen. When determining the correct pressure, always consult your local auto repair shop if you don’t know for sure. While the industry standard for a passenger vehicle is often anywhere between 30 and 40 PSI for standard vehicles, it’s best to get a professional recommendation. Paul Campanella’s Auto & Tire Center will evaluate your vehicle’s tire health and compatibility and base an accurate recommendation on their diagnosis.

Temperature changes, like intense heat, and worn tires may also be cause for replacement. If your tire treads are low, less friction will be generated during braking.

If your tires feel hot to the touch, that’s a sign of possible overheating. Asphalt is already hot from the summer sun, so your tires constant contact with the road will generate friction, which generates heat, which triggers the air molecules in your tires to expand. Hot air can lead to overinflating, causing tires to pop or prematurely wear.

It’s best to replace tires every five years at the latest, since rubber will age and crack no matter how much you keep up with maintenance. Any cracks, tears, or punctures in your tire require immediate attention.
