■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, 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 76 ft•lbf (103 N•m, 10.5 kgf•m) as soon as possible after changing wheels.
• 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.

When trouble arises
Remove any dirt or foreign matter
from the wheel contact surface.
If foreign matter is on the wheel contact
surface, the wheel nuts may loosen
while the vehicle is in motion, causing
the tire to come off.
Install the spare tire and loosely tighten each wheel nut by hand by approxi-
mately the same amount.
When replacing an aluminum wheel
with a steel wheel, tighten the wheel
nuts until the tapered portion comes
into loose contact with the disc
wheel seat.
When replacing an aluminum wheel
with an aluminum wheel, turn the
wheel nuts until the washers come
into contact with the disc wheel.
Lower the vehicle.

Stow the flat tire, tire jack and all tools.
■The spare tire
●GS350/GS200t: 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. 5 5 0 )
■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 may become lower when driving with the spare tire compared to when driv-
ing 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)
Install the compact spare tire on one of the front wheels of the vehicle. Perform the fol-
lowing steps and fit tire chains to the rear tires:
Replace a front tire with the compact spare tire.
Replace the flat rear tire with the tire removed from the front of the vehicle.
Fit tire chains to the rear tires.

cle. Do not use your spare tire on another vehicle.

■Speed limit when using the spare tire
Do not drive at speeds in excess of 50 mph (80 km/h) when a spare tire is installed on
the vehicle.
The spare tire is not designed for driving at high speeds. Failure to observe this precau-
tion may lead to an accident causing death or serious injury.
■After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in their storage
location to reduce the possibility of personal injury during a collision or sudden brak-
ing.

Do not fit tire chains to the spare tire.
Tire chains may damage the vehicle body and adversely affect driving performance.
■When replacing the tires

■If you have a flat tire
Do not continue driving with a flat tire.

repair, which could result in an accident.
Driving with a flat tire may cause a circumferential groove on the side wall.
In such a case, the tire may explode when using a repair kit.
