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 drivetrain
If a tire needs frequent inflating, have it checked by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional.

Instructions for checking tire inflation 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 or 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 pressure
that is even just a few pounds off can affect ride quality and handling.

Do not reduce tire inflation pressure after driving. It is normal for 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.
