2021 Lexus LC500C run-flat

2836-3. Do-it-yourself maintenance

Maintenance and care
Tires cannot be rotated.
When run-flat tires are installed, the
vehicle can be driven for a maximum of
100 miles (160 km) at a speed below
50 mph (80 km/h) after any tire goes
flat. (However, the vehicle speed may
not increase to near 50 mph [80
km/h] depending on weather or driv-
ing conditions.)
A run-flat tire has a mark on
the sidewall.
Make sure to replace the flat tire before
the vehicle has been driven for near 100
miles (160 km). Also, do not use a repaired
tire.
■Run-flat tires
●The run-flat tires are for only this vehicle.
Do not use the tires on other vehicles.
●Do not mix run-flat tires and normal tires.
●If non-genuine Lexus wheels are used, it
may be impossible to sufficiently demon-
strate the performanc e of run-flat tires.
Your vehicle is equipped with a tire
pressure warning system that uses tire
pressure warning valves and transmit-
ters to detect low tire inflation pressure
before serious problems arise.
If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and a
warning light. ( P.319) 
The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information
display. ( P.79)
The illustration used is intended as an
example, and may differ from the image
that is actually displayed on the multi-infor-
mation display.
■Routine tire inflation pressure checks
The tire pressure warning system does not
replace routine tire inflation pressure
checks. Make sure to check tire inflation
pressure as part of your routine of daily
vehicle checks.
■Situations in which the tire pressure
warning system may not operate prop-
erly
●In the following cases, the tire pressure
warning system may not operate prop-
erly.
• If non-genuine Lexus wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equipment) tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• An auxiliary-supported run-flat tire is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehi- cle, particularly around the wheels or
wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.
• If wheel without tire pressure warning valves and transmitters are used.

When trouble arises
Take your vehicle to the nearest Lexus
dealer or authorized tire dealer as
soon as possible if any tire goes flat.
The vehicle can be driven for a maximum
of 100 miles (160 km) at a speed below 50
mph (80 km/h) after the tire pressure
warning light comes on. ( P.319)
A run-flat tire has a mark on the
sidewall.
■In some condition (such as at high tem-
peratures)
You cannot continue driving for up to 100
miles (160 km).
■For the detailed information on run-flat
tires
See the tire warranty booklet.
If you have a flat tire
Your vehicle is not equipped with a
spare tire, but instead you can con-

flat tires even if any tire goes flat.
In this case, slow down and drive
with extra caution.

NOTICE
■When replacing the tires
When removing or fitting the wheels,
tires or the tire pr essure warning valve
and transmitter, contact your Lexus
dealer as the tire pressure warning valve
and transmitter may be damaged if not
handled correctly.
■When driving over bumps
If a vehicle has a flat tire, the vehicle
height will be lower than usual. Ensure
that nothing strikes the bottom of the
vehicle.
■To avoid damaging the tire pressure
warning valves and transmitters
When a tire is repaired with liquid seal-
ants, the tire pressure warning valve and
transmitter may not operate properly. If a
liquid sealant is used , contact your Lexus
dealer or other qualified service shop as
soon as possible. Make sure to replace
the tire pressure warning valve and
transmitter when replacing the tire.

Tire ply composition and materials
Plies are layers of rubber-coated parallel cords. Cords are the strands which form the plies
in a tire.
Radial tires or bias-ply tires
A radial tire has “RADIAL” on the sidewall. A tire not marked “RADIAL” is a bias-ply tire.
TUBELESS or TUBE TYPE
A tubeless tire does not have a tube and air is directly put into the tire. A tube type tire has a
tube inside the tire and the tube maintains the air pressure.
Load limit at maximum cold tire inflation pressure ( P.362)
Maximum cold tire inflation pressure ( P.362)
This means the pressure to which a tire may be inflated.
