Maintenance and care

When to replace your vehicle’s tires
Tires should be replaced if:
You have tire damage such as cuts, splits, cracks deep enough to expose the fab-
ric, and bulges indicating internal damage
A tire goes flat repeatedly or cannot be properly repaired due to the size or loca-
tion of a cut or other damage
If you are not sure, consult any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.
Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not registered,
the tire pressure warning system will not work properly. After driving for about
10 minutes, the tire pressure warning light blinks for 1 minute and stays on to
indicate a system malfunction.
Tire life
Any tire over 6 years old must be checked by a qualified technician even if it has
seldom or never been used or damage is not obvious.
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.
Low profile tires (except 16-inch tires)
Generally, low profile tires will wear more rapidly and tire grip performance will
be reduced on snowy and/or icy roads when compared to standard tires. Be sure
to use snow tires or tire chains
* on snowy and/or icy roads and drive carefully at
a speed appropriate for road and weather conditions.
*: Tire chains cannot be mounted on the 18-inch tires. Snow tires should be used
instead.
If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
