Is 40 PSI too high for tire pressure?
No, for most cars a tire pressure of 40 psi is too high. You might find 40 psi suitable for some vehicles, especially if they’re carrying heavier loads or if the manufacturer’s recommendation is close to that figure. However, it’s generally too high for most passenger cars, which usually recommend between 30-35 psi. On newer cars, the recommended pressure is most commonly listed on a sticker INSIDE the driver’s door. If there’s no sticker on the door, you can usually find the specs in the owner’s manual. Most passenger cars will recommend 32 to 35 psi in the tires when they’re cold.The proper tire pressure for a car is usually between about 30 and 35 psi. You can find the exact recommended tire pressure in your vehicle’s owner’s manual or on a placard located inside the driver’s door frame.Most passenger cars’ psi requirement will be between 30 to 35 psi, but several vehicles fall outside of that range and every vehicle will have specific requirements. Good tire air pressure ensures that tires wear evenly, provide a smooth ride, and increase fuel efficiency.
