sometimes use the letters ZR. For
those with a maximum speed
capability over 186 mph (299
km/h), tire manufacturers always
use the letters ZR. Note:
If the tire size does not begin
with a letter, this may mean it is
designated by either ETRTO
(European Tire and Rim Technical
Organization) or JATMA (Japan Tire
Manufacturing Association). You
may not find this information on all
tires because it is not required by
federal law.
Note: The tire suppliers may have
additional markings, notes or
warnings, for example standard
load, radial tubeless, etc.

You are strongly urged to buy a
reliable tire pressure gauge, as
automatic service station gauges
may be inaccurate. We
recommend the use of a digital or
dial-type tire pressure gauge
rather than a stick-type tire
pressure gauge.
Use the recommended cold
inflation pressure for optimum tire
performance and wear.
Under-inflation or over-inflation
may cause uneven treadwear
patterns.
Always inflate the tires to the
recommended inflation pressure
even if it is less than the maximum
inflation pressure information
found on the tire. The
recommended tire inflation
pressure is 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 seating
position), or Tire Label which is
located on the B-Pillar or the edge
of the driver door. Failure to follow
the tire pressure
recommendations can cause
uneven treadwear patterns and
adversely affect the way your
vehicle handles
Note:
Do not reduce tire pressure
to change the ride characteristics
of your vehicle. If you do not
maintain the tire pressures as
specified by Ford, your vehicle may
experience a condition known as
shimmy. This will cause severe
vibration and oscillations in the
steering wheel when your vehicle
travels over a bump or dip in the
road and is unable to dampen out
by itself. Significantly
under-inflated tires, incorrect tire
usage or any vehicle modifications
such as lift-kits can cause your
vehicle to shimmy. If your vehicle
begins to shimmy, slowly reduce
the speed of your vehicle by
pressing the brake pedal or
releasing the accelerator pedal. As
your vehicle speed reduces the
shimmy will cease.
The maximum inflation pressure
is the tire manufacturer's
maximum permissible pressure 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
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 seating
position), or Tire Label which is
located on the B-Pillar or the edge

Note:
Some spare tires operate at
a higher inflation pressure than the
other tires. For T-type mini-spare
tires, refer to the Dissimilar spare
wheel and tire assembly
information for a description. Store
and maintain at 60 psi (4.15 bar).
For full-size and dissimilar spare
tires, refer to the Dissimilar spare
wheel and tire assembly
information for a description. Store
and maintain at the higher of the
front and rear inflation pressure as
shown on the Tire Label.
Inspecting the Tires and Wheel
Valve Stems
Periodically inspect the tire treads
for uneven or excessive wear and
remove objects, for example
stones, nails or glass that may be
wedged in the tread grooves.
Check the tire and valve stems for
holes, cracks, or cuts that may
permit air leakage and repair or
replace the tire and replace the
valve stem. Inspect the tire
sidewalls for cracking, cuts,
bruises and other signs of damage
or excessive wear. If internal
damage to the tire is suspected,
have the tire removed and
inspected in case it needs to be
repaired or replaced. For your
safety, tires that are damaged or
show signs of excessive wear
should not be used because they
are more likely to blow out or fail. Incorrect or inadequate vehicle
maintenance can cause tires to
wear abnormally. Inspect all the
tires, including the spare,
frequently, and replace them if
one or more of the following
conditions exist:
Tire Wear
When the tread is worn down to
0.08 in (2 mm)
, tires must be
replaced to help prevent your
vehicle from skidding and
hydroplaning. Built-in treadwear
indicators, or wear bars, which
look like narrow strips of smooth
rubber across the tread will
appear on the tire when the tread
is worn down to
0.08 in (2 mm).
When the tire tread wears down
to the same height as these wear
bars, the tire is worn out and must
be replaced.

2021 Transit (TTH) Canada/United States of America, MK3J 19A321 AA enUSA, Edition date: 202010, Second-Printing Wheels and TiresE142546

Tire Damage
Periodically inspect the tire treads
and sidewalls for damage, for
example bulges in the tread or
sidewalls, cracks in the tread
groove or separation in the tread
or sidewall. If damage is observed
or suspected have the tire
inspected by a tire professional.
Tires can be damaged during
off-road use, so inspection after
off-road use is also
recommended.
Tire Age
WARNING: Tires degrade
over time depending on many
factors such as weather, storage
conditions, and conditions of use
(load, speed, inflation pressure)
the tires experience throughout
their lives. WARNING: In general, tires
should be replaced after six
years regardless of tread wear.
However, heat caused by hot
climates or frequent high loading
conditions can accelerate the
aging process and may require
tires to be replaced more
frequently. WARNING:
You should
replace your spare tire when you
replace the road tires or after six
years due to aging even if it has
not been used. Tire Replacement
Requirements WARNING:
Only use
replacement tires and wheels
that are the same size, load
index, speed rating and type
(such as P-metric versus
LT-metric or all-season versus
all-terrain) as those originally
provided by Ford. The
recommended tire and wheel
size may be found on either 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 the
Tire Label which is located on
the B-Pillar or edge of the
driver's door. If this information
is not found on these labels, then
you should contact your
authorized dealer as soon as
possible. Use of any tire or wheel
not recommended by Ford can
affect the safety and
performance of your vehicle,
which could result in an
increased risk of loss of vehicle
control, vehicle rollover, personal
injury and death. WARNING:
Always inflate
steel carcass tires with a remote
air fill with the person inflating
standing at a minimum of
12 ft
(3.66 m) away from the wheel
and tire assembly.

Have a flat serviced by an authorized
dealer in order to prevent damage to the
system sensors See Tire Pressure
Monitoring System (page 334). Replace
the spare tire with a road tire as soon as
possible. During repairing or replacing of
the flat tire, have the authorized dealer
inspect the system sensor for damage.
Dissimilar Spare Wheel and Tire
Assembly Information WARNING:
Failure to follow these
guidelines could result in an increased
risk of loss of vehicle control, injury or
death.
If you have a dissimilar spare wheel and
tire, then it is intended for temporary use
only. This means that if you need to use it,
you should replace it as soon as possible
with a road wheel and tire assembly that
is the same size and type as the road tires
and wheels that were originally provided
by Ford. If the dissimilar spare tire or wheel
is damaged, it should be replaced rather
than repaired.
A dissimilar spare wheel and tire assembly
is defined as a spare wheel and tire
assembly that is different in brand, size or
appearance from the road tires and wheels
and can be one of three types:

Locking Lug Nuts (If Equipped)
You can obtain replacement locking lug
nuts or a locking lug nut key using the
reference number certificate.
The locking lug nut key is located in the
glove box or in the storage compartment
in the front right-hand side stepwell.
Vehicles With a Spare Wheel
The spare wheel is under the rear of your
vehicle.
If the spare wheel is the same type and
size as your vehicle road wheel, you can fit
the spare wheel and continue to drive in
the normal manner.
If the spare wheel is not the same type and
size as your vehicle road wheel, it has a
label showing the maximum driving speed
limit. Note:
If your vehicle is fitted with a tire
pressure monitoring system, the warning
indicator will flash if you fit the spare wheel
to your vehicle. To restore the correct
operation of the tire pressure monitoring
system, you must have the repaired road
wheel and tire assembly refitted to your
vehicle. See
Tire Pressure Monitoring
System (page 334). To prevent damage
