Maximum load of tire
Check that the maximum load of the re
placement tire is greater than 1/2
of the Gross Axle Weight Ratings (GAWR) of either the front axle or the
rear axle, whichever is greater.
nTire types
lSummer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Since summer tires do not have the same
traction performance as snow tires, summer tires are inadequate for
driving on snow-covered or icy ro ads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When install-
ing snow tires, be sure to replace all four tires.
lAll season tires
All season tires are designed to provide better traction in snow and to
be adequate for driving in most winter conditions as well as for use
year-round. All season tires, however, do not have adequate traction
performance compared with snow tires in heavy or loose snow. Also, all
season tires fall short in acceleration and handling performance com-
pared with summer tires in highway driving.
lSnow tires
For driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the or iginally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations fo r possible restrictions. Snow tires
should be installed on all wheels. ( P. 221)
nInitializing the tire pressure warn ing system (vehicles with a tire
pressure warning system)
Initialize the system with the tire infl ation pressure adjusted to the speci-
fied level.
nIf the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tire s as snow tires is lost.
For the GAWR, see the Certification
Label. For the maximum load of the tire,
see the load limit at maximum cold tire
inflation pressure mentioned on the
sidewall of the tire. (

CAUTION
nWhen inspecting or replacing tires
Observe the following precautions 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 accident
resulting in death or serious injury.
lDo not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
lDo not use tire sizes other than those recommended by Toyota.
lDo not mix differently constructed ti res (radial, bias-belted or bias-ply
tires).
lDo not mix summer, all season and snow tires.
lDo not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
nWhen initializing the tire pressure warning system (vehicles with a
tire pressure warning system)
Do not operate the tire pressure warning reset switch without first
adjusting the tire inflation pressure to the specified level. Otherwise, the
tire pressure warning light may not come on even if the tire inflation
pressure is low, or it may come on when the tire inflation pressure is
actually normal.

Maintenance and care
COROLLA_TMMMS_TMMC_U (OM12J84U)
NOTICE
nRepairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps (vehicles with a tire pressure warn-
ing system)
lWhen removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact your Toyota dealer as the tire pres-
sure warning valves and transmitters may be damaged if not handled
correctly.
lWhen replacing tire valve caps, do not use tire valve caps other than
those specified. The cap may become stuck.
nTo avoid damage to the tire pressure warning valves and transmit-
ters (vehicles with a tire pressure warning system)
When a tire is repaired with liquid sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sealant is
used, contact your Toyota dealer or other qualified service shop as soon
as possible. Make sure to replace the tire pressure warning valve and
transmitter when replacing the tire. ( P. 455)
nDriving on rough roads
Take particular care when driving on roads with loose surfaces or pot-
holes.
These conditions may cause losses in tire inflation pressure, reducing
the cushioning ability of the tires. In addition, driving on rough roads
may cause damage to the tires themselves, as well as the vehicle’s
wheels and body.
nLow profile tires (17-inch tires)
Low profile tires may cause greater damage than usual to the tire wheel
when sustaining impact from the road surface. Therefore, pay attention
to the following:
lBe sure to use proper tire inflation pressure. If tires are under-inflated,
they may be damaged more severely.
lAvoid potholes, uneven pavement, curbs and other road hazards. Fail-
ure to do so may lead to severe tire and wheel damage.
nIf tire inflation pressure of e ach tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
lCheck only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been
driven for more than 1 mile or 1.5 km, you will get an accurate cold tire
inflation pressure reading.
lAlways use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based only on its appear-
ance.
lIt is normal for the tire inflation pressure to be higher after driving as
heat is generated in the tire. Do not
reduce tire inflation pressure after
driving.
lNever exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is
balanced.
CAUTION
nProper inflation is critical to save tire performance
Keep your tires properly inflated.
If the tires are not properly inflated, the following conditions may occur
which could lead to an accident resulting in death or serious injury:
lExcessive wear
lUneven wear
lPoor handling
lPossibility of blowouts result ing from overheated tires
lAir leaking from between tire and wheel
lWheel deformation and/or tire damage
lGreater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges in the road, etc.)
NOTICE
nWhen inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed, dirt or moisture may get into the valve and
cause an air leak, resulting in decreased tire inflation pressure.

Maintenance and care
COROLLA_TMMMS_TMMC_U (OM12J84U)
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width and
inset
*.
Replacement wheels are available at your Toyota dealer.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
l Wheels of different sizes or types
l Used wheels
l Bent wheels that have been straightened
l Use only Toyota wheel nuts and wrenches designed for use with
your aluminum wheels.
l When rotating, repairing or changi ng your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
l Be careful not to damage the aluminum wheels when using tire
chains.
l Use only Toyota genuine balance weights or equivalent and a plas-
tic or rubber hammer when balancing your wheels.
nWhen replacing wheels (vehicles with a 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 system to
provide advance warning in the event of a loss in tire inflation pressure.
Whenever wheels are replaced, tire pressure warning valves and trans-
mitters must be installed. ( P. 455)
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.

CAUTION
nWhen replacing wheels
lDo not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may result in a loss of handling control.
lNever use an inner tube in a leaking wheel which is designed for a
tubeless tire. Doing so may result in an accident, causing death or seri-
ous injury.
nWhen installing the wheel nuts
lNever 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 grease 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 oil or
grease from the wheel bolts or wheel nuts.
nUse 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.
NOTICE
nReplacing tire pressure warning va lves and transmitters (vehicles
with a tire pressure warning system)
lBecause tire repair or replacement may affect the tire pressure warn-
ing valves and transmitters, make sure to have tires serviced by your
Toyota dealer or other qualified service shop. In addition, make sure to
purchase your tire pressure warning valves and transmitters at your
Toyota dealer.
lEnsure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly
with non-genuine wheels.
lBe 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.
