The recommended tire pressure for most passenger cars typically ranges between 28 and 36 PSI (pounds per square inch) when the tires are cold, meaning the car has been stationary for at least three hours or driven less than about 1.6 km

. To find the exact recommended PSI for your vehicle:

• Check the sticker located on the inside of the driver’s door jamb.
• Refer to the vehicle’s owner manual.

This recommended pressure is optimized for safe handling, braking, fuel efficiency, and tire longevity

. Important notes:

• The pressure on the tire sidewall is the maximum pressure the tire can safely hold, not the recommended pressure for everyday driving

• Over-inflating tires to the maximum pressure can cause poor handling, increased wear in the center of the tread, and risk of blowouts

• Under-inflation can cause uneven wear, poor fuel efficiency, and safety issues

• Tire pressure should be checked with a reliable gauge when tires are cold for an accurate reading

In summary, use the manufacturer’s recommended PSI found on your car’s door sticker or manual, usually between 28 and 36 PSI for passenger cars, and always check when tires are cold for best accuracy
