The correct tire pressure for a Ford F-150 is 35 psi when cold. Proper tire pressure specifications appear on a sticker located on the driver’s-side door jamb or in the vehicle owner’s manual.
Tire pressure settings are often a trade between vehicle handling and gas mileage. Tires inflated to a higher pressure may improve on fuel economy at the expense of less traction. Conversely, under-inflated tires may improve handling at the expense of better mileage.
Inflating tires to the correct pressure ensures maximum safety and vehicle performance. Improperly inflated tires may result in tire failure, uneven tread wear, poor braking and vehicle handling. The F-150 comes with a monitoring system and indicator light that appears on the instrument panel, instructing the driver to check his tire pressure.
