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 103 ft•lbf (140 N•m,
14.3 kgf•m) 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.
