Lincoln Navigator (2005) SUV [14/24] Inspecting and inflating your tires

Maximum Permissible Inflation Pressure

Tire manufactures maximum permissible pressure and/or the pressure at

which the maximum load can be carried by the tire. This pressure is

normally higher than the manufacturer’s recommended cold inflation

pressure which can be found on either the tire label or certification label

which is located on the structure by the trailing edge of the driver’s door

or the edge of the driver’s door. The cold inflation pressure should never

be set lower than the recommended pressure on the vehicle

label.

Note: You may not find this information on all tires because it is not

required by federal law.

The tire suppliers may have additional markings, notes or warnings such

as standard load, radial tubeless, etc.

Tires can slowly lose pressure due to normal use or due to changes in

weather. For example, a 10 degree temperature drop can cause a

corresponding drop of 7 kPa (1 psi) in tire inflation pressure.

Maintain proper tire inflation pressure. Under-inflation is the

most common cause of tire failures. Under-inflation increases

sidewall flexing and rolling resistance, resulting in heat buildup and

internal damage to the tire. Operating your vehicle with under-inflated

tires may result in severe tire cracking, tread separation or tire

“blowout”, which can lead to loss of vehicle control, vehicle rollover,

serious injury or death.

The Ford recommended inflation pressure is based on cold tire pressure.

Tire pressure increases even after driving short distances, so try to check

tire inflation pressures before driving. If you are checking tire pressure

when the tire is hot, (i.e. driven more than 1.6 km [1mile]), never “bleed”

or reduce air pressure. A hot tire with a tire pressure at or below

recommended cold inflation pressure could be significantly under-inflated.

To check the pressure in your tire(s):

1. Make sure the tires are cool, meaning they are not hot from driving

even a mile.

Note: If you have to drive a distance to get air for your tire(s), check

and record the tire pressure first and add the appropriate air pressure

when you get to the pump. It is normal for tires to heat up and the air

pressure inside to go up as you drive. Never “bleed” or reduce air

pressure when tires are hot.

2. Remove the cap from the valve on one tire, then firmly press the tire

gauge onto the valve.
