■ When installing the tire
Failure to follow these precautions could
cause the wheel nuts to loosen and the
tire to fall off, resulting in death or serious
injury.
● Never use oil or grease on the wheel
bolts or wheel nuts.
Oil and grease may cause the wheel
nuts to be excessively tightened, lead-
ing 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 a serious accident.
Remove any oil or grease from the
wheel bolts or wheel nuts.
● Have the wheel nuts tightened with a
torque wrench to 140 N•m (14.3
kgf•m, 103.3 ft•lbf) as soon as possible
after changing wheels.
● Do not attach a heavily damaged
wheel ornament, as it may fly off the
wheel while the vehicle is moving.
● When installing a tire, only use wheel
nuts that have been specifically
designed for that wheel.
● If there are any cracks or deformations
in the bolt screws, nut threads or bolt
holes of the wheel, have the vehicle
inspected by your Lexus dealer.
