Maintenance and care
COROLLA_TMMMS_TMMC_U
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.
■When replacing wheels (vehicles with a tire pressure warning sy s-
tem)
The wheels of your vehicle are equipped with tire pressure warn ing
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. 441)
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.

WARNING
■When replacing wheels
●Do 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.
●Never use an inner tube in a leaking wheel which is designed fo r a
tubeless tire. Doing so may resu lt in an accident, causing death 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 tight ened,
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, caus ing an
accident and resulting in death or serious injury. Remove any oil 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.
NOTICE
■Replacing tire pressure warning va lves and transmitters (vehicles
with a tire pressure warning system)
●Because tire repair or replacement may affect the tire pressure warn-
ing valves and transmitters, make sure to have tires serviced b y 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.
●Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work prop erly
with non-genuine wheels.
●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 o r serious injury.
