The tire pressure information is usually printed on a placard or sticker visible when you open the driver’s door, but on some 4 door sedans, you’ll find it by opening the rear passenger side door. Common locations are the door jamb and doorpost. You might also find the tire pressure information placard on the fuel door, glove box door, or even under the hood.
This information is the operating pressure recommended by the manufacturer and will include the tire size information. Sometimes referred to as the correct fill pressure, it’s measured in pounds per square inch (psi). Tire pressure affects braking, handling, fuel economy, and how long the tire can go before it needs replacement.
There’s a big difference between tire pressure information and the maximum tire pressure, which can be found on the tire sidewall. Max tire pressure is the maximum pressure the tire can handle safely. However, you shouldn’t drive with tires inflated to their maximum pressure value or you’ll have excessive tire wear and a possible blowout due to the air expanding as the tire heats up while driving.
If you can’t find the tire pressure information, you can consult your owner’s manual. The manual should have the recommended pressure level for your car’s tires. Additionally, you can visit the website of the company that manufactures either your car’s model or the tire.
If you install new tires that differ from your stock tires in size and capabilities, you’ll need to follow the tire manufacturer’s recommended pressure value. Otherwise, you might underinflate or overinflate the new tires, increasing your chances of a tire blowout.
