Wheels
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 any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
● Use only Toyota wheel bolts and wrenches designed for use with
your aluminum wheels.
● When rotating, repairing or changing your tires, check that the
wheel bolts are still tight after driving 1600 km (1000 miles).
● Be careful not to damage the aluminum wheels when using tire
chains.
● Use only Toyota genuine balance weights 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.

Slightly loosen the wheel bolts
(one turn).
Turn the tire jack until the notch
of the jack is in contact with the
jack point.
The jack point guides are located
under the rocker panel. They indi-
cate the jack point positions.
Raise the vehicle until the tire is
slightly raised off the ground.
Remove all the wheel bolts and
the tire.
When resting the tire on the
ground, place the tire so that the
wheel design faces up to avoid
scratching the wheel surface.

WARNING
■Replacing a flat tire
● Observe the following precautions.
Failure to do so may result in serious injury:
• Do not try to remove the wheel ornament by hand. Take due care in
handling the ornament to avoid unexpected personal injury.
• Do not touch the disc wheels or the area around the brakes immediately
after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around
the brakes will be extremely hot. Touching these areas with hands, feet
or other body parts while changing a tire, etc., may result in burns.
● Failure to follow these precautions could cause the wheel bolts to loosen
and the tire to fall off, resulting in death or serious injury.
• Never use oil or grease on the wheel bolts.
Oil and grease may cause the wheel bolts to be excessively tightened,
leading to bolt or disc wheel damage. Remove any oil or grease from
the wheel bolts.
• Have the wheel bolts tightened with a torque wrench to 103 N·m
(10.5 kgf·m, 76 ft·lbf) as soon as possible after changing wheels.
• When installing a tire, only use wheel bolts that have been specifically
designed for that wheel.
• If there are any cracks or deformations in the bolt, bolt threads or bolt
holes of the wheel, have the vehicle inspected by any authorized Toyota
dealer or repairer, or another dul y qualified and equipped professional.

Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.
If foreign matter is on the wheel
contact surface, the wheel bolts
may loosen while the vehicle is in
motion, causing the tire to come
off.
Install the spare tire and loosely tighten each wheel bolt by hand by
approximately the same amount.
When replacing a steel wheel
with a steel wheel, tighten the
wheel bolts until the tapered
portion comes into loose con-
tact with the disc wheel seat.
When replacing an aluminum
wheel with a steel wheel,
tighten the wheel bolts until the
tapered portion comes into
loose contact with the disc
wheel seat.
Lower the vehicle.
