What is the proper tire pressure for a lexus es 300 (2001)

look inside the door jam on the drivers side,it will tell you the proper tire pressure

28 to 32 PSI. 32 will get you better fuel economy, 28 will give you a better ride. You should look on the tire sidewall for that information, as well as on the door post.

If you still have the owners manual look in there and it will tell you and if you do not have it. Then open you driver-side door and look inside for a sticker and it will tell you on that.

The proper pressure will be in the door of the vehicle. It is set by the car manufacturer. Do not go by the psi on the tires. That is showing the maximum recommended psi for the tires.

The proper air pressure will be in the manual or the door of the car.
