Rotate the tires in the order shown.
To equalize tire wear and help extend ti re life, Lexus recommends that tire rota-
tion is carried out approximately every 10000 km (6000 miles).
Do not fail to initialize the tire pressu re warning system after tire rotation.
Your vehicle is equipped with a tire pressure warning system that uses tire pres-
sure warning valves and transmitters to detect low tire inflation pressure before
serious problems arise.
If the tire pressure drops below a predeter mined level, the driver is warned by a
warning light. ( P. 578)
◆Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pr essure warning valves and transmitters
must also be installed.
When new tire pressure wa rning valves and transmitters are installed, new ID
codes must be registered in the tire pressure warning computer and the tire
pressure warning system must be initia lized. Have tire pressure warning valve
and transmitter ID codes registered by any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer. ( P. 527)

■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cr acks deep enough to expose the fabric, and
bulges indicating internal damage
●A tire goes flat repeatedly or cannot be prop erly repaired due to the size or location of a cut or other damage
If you are not sure, consult any authorized Lexus retailer or Lexus authorized repairer, or
any reliable repairer.
■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 proper ly. After driving for about 10 minutes, the tire pressure warning light blinks for 1 minu te and stays on to indicate a system malfunc-
tion.
■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 syst em does not replace routine tire inflation pressure checks.
Make sure to check tire inflat ion pressure as part of your routine of daily vehicle checks.
■Low profile tires (except 16-inch tires)
Generally, low profile tires w ill wear more rapidly and tire grip performance will be
reduced on snowy and/or icy roads when comp ared to standard tires. Be sure to use
snow tires or tire chains* on snowy and/or icy roads and drive carefully at a speed appro- priate 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 tire s as snow tires is lost.
