The best time to check your car's tire pressure is in the morning, before the tires have had a chance to warm up from driving. This is because tire pressure increases as the tires warm up, so checking them when they're cold will give you a more accurate reading. Tire pressure is important for fuel efficiency, tire wear, and overall vehicle handling and performance. Underinflated tires can lead to increased fuel consumption and uneven tire wear, while overinflated tires can affect the vehicle's handling and ride comfort. It is recommended that you check your tire pressure at least once a month and before any long trips. This simple maintenance task can help ensure your safety on the road and extend the life of your tires.

Frequently asked questions
It is recommended that you check your tire pressure at least once a month. This is because tire pressure can change with the temperature outside, and you could be losing about 1 PSI every month after you fill your tires.
The ideal time to check your tire pressure is when your tires haven't been used in a while and have been sitting outside in the shade. This is because tire pressure varies with temperature. Checking your tires first thing in the morning or a few hours after your vehicle has been parked in the shade is best.
If your tires are underinflated, it can adversely affect handling and stopping distance, make the tires more prone to blowouts, affect ride quality, and result in uneven tread wear. It can also lower your gas mileage and cause the vehicle body to sit lower than usual on the ground.
The correct tire pressure for your car can be found on a sticker on the driver's side door jamb, in your owner's manual, or near the trunk lid, the console, or the fuel door. The manufacturer's recommended tire pressure is usually between 30 and 35 pounds per square inch (PSI).
Overinflated tires can be dangerous, especially when cornering at high speeds. They can also give you a bouncy ride.
