Incorrect tire pressure can reduce tire life and make your vehicle less safe to drive.
Low tire pressure causes excessive wear, poor handling, decreased fuel economy, and the possibility of blowouts from overheating tires. Low pressure can also cause poor tire bead sealing. If pressure is too low, there is a possibility of wheel damage and/or tire separation.
High tire pressure results in a rough ride, poor handling, and excessive wear in the center of the tire tread from potholes in the road.
If your tire requires frequent inflation, have it checked by your Toyota dealer.
Instructions for checking tire pressure
The pressure should only be checked when the tyres are cold.
If the vehicle has been parked for at least 3 hours and has not been driven more than 1.5 km after that, an accurate cold tire pressure reading can be obtained.
Always use a tire pressure gauge.
Tire appearances can be deceiving. Also, tire pressure, even if it is only slightly underinflated, can impair handling and ride.

Do not deflate or reduce tire pressure after driving.
It is normal for a tire to have increased pressure after driving.
Be sure to install the tire valve caps.
Without the inflation valve caps, dirt or moisture can get into the valve stem and cause air leaks. If the caps are lost, new caps should be installed as soon as possible.
