Tire Inflation Pressure - Lexus LS460 2011 Owner's Manual

Tire inflation pressure

Make sure to maintain the proper tire inflation pressure. Tire inflation
pressure should be checked at least once per month. However, Lexus
recommends that tire inflation pressure be checked once every two
weeks.

Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:

Reduced fuel efficiency

Reduced driving comfort and tire life

Reduced safety

Damage to the drive train
If a tire needs frequent refilling, have it checked by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.

Instructions for checking tire pressure
When checking tire inflation pressure, observe the following:

Check 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, you will get an accurate cold tire
inflation pressure reading.

Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation
pressures that are even just a few pounds off can degrade ride and han-
dling.

Do not bleed or reduce tire inflation pressure after driving. It is normal
for the tire inflation pressure to be higher after driving.

Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is
balanced.
