It’s hard to tell whether your tires are properly inflated just by looking at them. Even when your tires are underinflated or nearly flat, it can be difficult to feel it on the road. If you’ve been driving with underinflated tires, there might even be damage to the inner parts of the tire you can’t see.
That’s why it’s important to regularly check your tire pressure. We recommend doing so at least once each month and before a long trip.
You should check your tire pressure when tires are cold – in other words, before you’ve driven on them. Driving even a short distance causes tires to heat up and air pressure to increase.
We recommend that you manually monitor and check tire pressure inflation with a pressure gauge. Your tires should have the recommended pressure listed by your vehicle's manufacturer. This information can be found in the vehicle owner's manual and often on a placard located in the vehicle's door jamb, inside the fuel hatch, or on the glove compartment door.
If you have a plus-size fitment that requires a higher inflation pressure, your tire pressure monitoring system will require re-calibration to the new inflation pressure. Refer to your tire dealer/installer of plus-size tires for proper inflation pressure.
Make sure your spare tire is properly inflated, too, whether it’s a full-sized spare or a miniature.
If your tire pressure sensor generates improper monitoring or signals, we recommend that you consult your owner’s manual provided with your vehicle and follow-up with your vehicle’s manufacturer.
