The recommended tire pressure for your vehicle can vary depending on the make and model of your car, tire size, and load requirements. The recommended PSI (pounds per square inch) for most passenger cars falls between 28 and 36 PSI. To find the recommended tire pressure for your vehicle, you can check the manufacturers recommendation, which is usually printed on a label inside your car. This label can be found on the edge of the vehicles door, on the doorpost, or in the glove box. The recommended tire pressure is a cold inflation pressure, which means the pressure check should be done after the vehicle has been sitting in the shade for a while. It is important to note that some vehicles have different recommended inflation pressures for the front and rear tires, and sometimes a higher pressure (usually for the rear) will be listed if youre carrying a heavy load. The pressures listed are for the tire size that originally came on the vehicle, which is also listed on the sticker. It is recommended to check tire pressure when your tires are cold, before or at least three hours after driving. To check your tire pressure, you should remove the valve cap, attach the tire pressure gauge, and compare the gauges tire pressure reading to the recommended PSI for your vehicle. If the pressure is too high or too low, it will need to be adjusted.
