If a tire needs frequent inflating, have it checked by your toyota dealer.
Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
If your vehicle has been parked for at least 3 hours or has not been driven for more than 1 mile or 1.5 Km, you will get an accurate cold tire inflation pressure reading.
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.
Passengers and luggage weight should be placed so that the vehicle is balanced.
Caution
Proper inflation is critical to save tire performance
