Maximum Permissible Inflation
Pressure is the tire manufacturer's
maximum permissible pressure and
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 the Safety Compliance Certification
Label (affixed to either the door hinge
pillar, door-latch post, or the door
edge that meets the door-latch post,
next to the driver's seating position),
or Tire Label which is located on the
B-Pillar or the edge of the driver's
door. The cold inflation pressure
should never be set lower than the
recommended pressure on the Safety
Compliance Certification Label or Tire
Label.
When weather temperature changes
occur, tire inflation pressures also
change. A 10°F (6°C) temperature drop
can cause a corresponding drop of 1
psi (7 kPa) in inflation pressure. Check
your tire pressures frequently and
adjust them to the proper pressure
which can be found on the Safety
Compliance Certification Label or Tire
Label.
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.
MKZ (CC9)
Wheels and Tires
Note: If you are checking tire pressure
when the tire is hot, (for example
driven more than 1 mile [1.6
kilometers]), never bleed or reduce air
pressure. The tires are hot from
driving and it is normal for pressures
to increase above recommended cold
pressures. A hot tire at or below
recommended cold inflation pressure
could be significantly under-inflated.
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.
2. Remove the cap from the valve on
one tire, then firmly press the tire
gauge onto the valve and measure
the pressure.
3. Add enough air to reach the
recommended air pressure.
Note: If you overfill the tire, release
air by pressing on the metal stem in
the center of the valve. Then recheck
the pressure with your tire gauge.
4. Replace the valve cap.
5. Repeat this procedure for each tire,
including the spare.
