Toyota LEXUS LS430 2005 Manual page 488

You should check the tire inflation pressures every two
weeks, or at least once a month. And do not forget the
spare! The pressure for the spare tire should be the
same as that for the standard tire. (See pages 463
through 465.)
The following instructions for checking tire inflation
pressure should be observed:
D 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 inflation pressure reading.
D Always use a tire pressure gauge. The appearance
of the tire can be misleading. Besides, tire inflation
pressures that are even just a few pounds off can
degrade ride and handling.
D Do not bleed or reduce tire inflation pressure after
driving. It is normal for the tire inflation pressure to
be higher after driving.
D Never exceed the vehicle capacity weight.
Passengers and luggage weight should be located so
that the vehicle is balanced.
