■Replacing a flat tire
●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 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, 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, caus ing 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 76 ft•lbf (103 N•m,
10.5 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.

●RC350: The spare tire is identified by the label “TEMPORARY USE ONLY” on the
tire sidewall.
●Use the spare tire temporarily, and only in an emergency.
●Make sure to check the tire inflation pressure of the spare tire.
( P. 6 1 4 )
■When using the spare tire
As the spare tire is not equipped with a tire pressure warning valve and transmitter, low
inflation pressure of the spare tire will not be indicated by the tire pressure warning sys-
tem. Also, if you replace the spare tire after the tire pressure warning light comes on, the
light remains on.
■When the spare tire is equipped
The vehicle becomes lower when driving with the spare tire compared to when driving
with standard tires.
■If you have a flat rear tire on a road covered with snow or ice (vehicles with front and
rear tires of the same size except for ve hicles with 235/40R19 tires and LDH system)
Install the spare tire on one of the front wheels of the vehicle. Perform the following steps
and fit tire chains to the rear tires: Replace a front tire with the spare tire.
Replace the flat rear tire with the tire removed from the front of the vehicle.
