2019 TOYOTA TACOMA tire size

5227-3. Do-it-yourself maintenance
Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tire infla-
tion pressure before serious problems arise.
● If the tire pressure drops below a predetermined level, the dri ver is
warned by a warning light. ( P. 570)
● The tire pressure detected by
the tire pressure warning sys-
tem can be displayed on the
multi-information display.
◆Installing tire pressure warn ing valves and transmitters
When replacing tires or wheels, tire pressure warning valves an d
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new ID codes must be registered in the tire pressure
warning computer and the tire pressure warning system must be
initialized. Have tire pressure warning valve and transmitter I D
codes registered by your Toyota dealer. ( P. 524)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the fol-
lowing circumstances:
● When rotating the tires.
● When changing the tire size.
When the tire pressure warning sy stem is initialized, the current tire
inflation pressure is set as the benchmark pressure.

◆Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve an d
transmitter, it is necessary to register the ID code. Have the ID code
registered by your Toyota dealer.
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough t o
expose the fabric, and bulges indicating internal damage
●A tire goes flat repeatedly or c annot be properly repaired due to the size
or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
■Replacing tires and wheels (vehicles with the tire pressure war ning
system)
If the ID code of the tire press ure warning valve and transmitt er is not reg-
istered, the tire pressure warni ng system will not work properly. A f t e r d r i v -
ing for about 20 minutes, the tire pressure warning light blink s for
1 minute and stays on to indica te a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified techni cian even
if it has seldom or never been u sed or damage is not obvious.
■Routine tire inflation pressure checks (vehicles with the tire pressure
warning system)
The tire pressure warning system does not replace routine tire inflation
pressure checks. Make sure to chec k tire inflation pressure as part of
your routine of daily vehicle checks.

5267-3. Do-it-yourself maintenance
■Initializing the tire pressure warning system (if equipped)
Initialize the system with the tire inflation pressure adjusted to the speci-
fied level.
■If the tread on snow tires wea rs down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost.
■Situations in which the tire pressure warning system may not op er-
ate properly (if equipped)
●In the following cases, the tire pressure warning system may no t operate
properly.
• If non-genuine Toyota wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equip-
ment) tire.
• A tire has been replac ed with a tire that is not of the specif ied size.
• Tire chains, etc., are equipped.
• An auxiliary-supported ru n-flat tire is equipped.
• If a window tint that affects the radio wave signals is instal led.
• If there is a lot of snow or ice on the vehicle, particularly around the
wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the sp ecified
level.
• If wheel without the tire pressure warning valve and transmitt er is
used.
• If the ID code on the tire pressure warning valves and transmi tters is
not registered in the tire pressure warning computer.
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio stat ion, large
display, airport or other facilit y that generates strong radio waves or
electrical noise
• When carrying a portable radio, cellular phone, cordless phone or
other wireless communication device
●When the vehicle is parked, the time taken for the warning to s tart or go
off could be extended.
●When tire inflation pressure declines rapidly for example when a tire has
burst, the warning may not function.

WARNING
■When inspecting or replacing tires
Observe the following precaut ions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accide nt
resulting in death o r serious injury.
●Do not mix tires of different ma kes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other th an those recommended by Toyota.
●Do not mix differently constructed tires (radial, bias-belted o r bias-ply
tires).
●Do not mix summer, all season and snow tires.
●Do not use tires that have been used on another vehicle.
Do not use tires if you do not kn ow how they were used previously.
■When initializing the tire pressure warning system (if equipped )
Do not operate the tire pressure warning reset switch without first
adjusting the tire inflation pressure to the specified level. O therwise, the
tire pressure warning light may not come on even if the tire in flation
pressure is low, or it may come on when the tire inflation pres sure is
actually normal.

Maintenance and care
Wheels
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim wid th and
inset
*.
Replacement wheels are available at your Toyota dealer.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that hav e been straightened
● Use only Toyota wheel nuts and wrenches designed for use with
your aluminum wheels.
● When rotating, repairing or changi ng your tires, check that the
wheel nuts are still tight afte r driving 1000 miles (1600 km).
● Be careful not to damage the aluminum wheels when using tire
chains.
● Use only Toyota genuine balance we ights or equivalent and a plas-
tic or rubber hammer when balancing your wheels.
If a wheel is bent, cracked or heavily corroded, it should be
replaced. Otherwise, the tire may separate from the wheel or
cause a loss of handling control.

5347-3. Do-it-yourself maintenance
■When replacing wheels (vehicles with the tire pressure warning sys-
tem)
The wheels of your vehicle are equipped with tire pressure warning
valves and transmitters that allow the tire pressure warning sy stem to
provide advance warning in the event of a loss in tire inflatio n pressure.
Whenever wheels are replaced, tir e pressure warning valves and trans-
mitters must be installed. ( P. 522)
WARNING
■
When replacing wheels
●Do not use wheels that are a different size from those recommen ded in
the Owner’s Manual, as this may result in a loss of handling control.
●Never use an inner tube in a leaking wheel which is designed fo r a
tubeless tire. Doing so may result in an accident, causing deat h or seri-
ous injury.
■When installing the wheel nuts
●Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or g rease can
cause the wheel nuts to loosen and the wheel may fall off, causing an
accident and resulting in death or serious injury. Remove any o il or
grease from the wheel bolts or wheel nuts.
■Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing
an accident.
●Be sure to install the wheel nuts with
the tapered ends facing inward.
Installing the nuts with the tapered
ends facing outward can cause the
wheel to break and eventually cause
the wheel to come off while driving,
which could lead to an accident
resulting in death or serious injury.Tapered

When trouble arises
WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact your Toyota
dealer. The vehicle will become extremely unstable during braki ng, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.
■ If the tire pressure warning light comes on (if equipped)
Be sure to observe the following precautions. Failure to do so could cause a
loss of vehicle control and result in death or serious injury.
● Stop your vehicle in a safe place as soon as possible. Adjust the tire infla-
tion pressure immediately.
● If the tire pressure warning light comes on even after tire inf lation pressure
adjustment, it is probable that you have a flat tire. Check the tires. If a tire
is flat, change it with the spare tire and have the flat tire repaired by the
nearest Toyota dealer.
● Avoid abrupt maneuvering and braking. If the vehicle tires dete riorate, you
could lose control of the steering wheel or the brakes.
■ If a blowout or sudden air leakage should occur (vehicles with the tire
pressure warning system)
The tire pressure warning system may not activate immediately.
■
Maintenance of the tires (vehicles with the tire pressure warning
system)
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation p ressure
label (tire and load information label). (If your vehicle has t ires of a dif-
ferent size than the size indicated on the vehicle placard or t ire inflation
pressure label [tire and load information label], you should de termine
the proper tire inflation p ressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS -tire pressure warning system) that
illuminates a low tire pressure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Acco rdingly,
when the low tire pressure telltale (tire pressure warning ligh t) illumi-
nates, you should stop and check your tires as soon as possible , and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread lif e, and may
affect the vehicle’s handling and stopping ability.
