242High tire pressure produces a harsh ride, handling problems,
excessive wear at the center of the tire tread, and a greater possibility
of tire damage from road hazards.
The following instructions for checking tire pressure should be
observed:
The pressure should be checked only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has not
been driven for more than 1.5 km or 1 mile since, you will get an
accurate cold tire pressure reading.
Always use a tire pressure gauge. The appearance of the tire can
be misleading. Besides, tire pressures that are even just a few
pounds off can degrade handling and ride.
Do not bleed or reduce tire pressure after driving. It is normal
for the tire pressure to be higher after driving.
Never exceed the vehicle capacity weight. The passengers and
luggage weight should be located so that the vehicle is balanced.
Be sure to reinstall the tire valve caps. Without the valve caps,
dirt or moisture could get into the valve core and cause air
leakage. If the caps have been lost, have new ones put on as soon
as possible.
ROTATING TIRES
63L007-2
To equalize tire wear and help extend tire life, Lexus
recommends that you rotate your tires approximately every
12000 km (7500 miles). However, the most appropriate timing
for tire rotation may vary according to your driving habits and
road surface conditions.
The wheel assemblies must be rotated as illustrated above. If the
optional chrome plated wheels are mounted, rotate them as pattern
A. For the standard wheels, use pattern B.
When rotating tires, check for uneven wear and damage. Abnormal
wear is usually caused by incorrect tire pressure, improper wheel
alignment, out of balance wheels, or severe braking.
Before storing radial, snow or studded tires, mark the direction of
rotation and be sure to install them in the same direction when using
them again. Tires should be stored in a cool dry place.
