Toyota Yaris: Tires / Tire Inflation Pressure

Toyota Yaris XP210 (2020-2024) Owner's Manual / Maintenance and Care / Owner Maintenance / Tires / Tire Inflation Pressure

Inspect all tire pressures monthly (including the spare) when the tires are cold. Maintain recommended pressures for the best ride, handling, and minimum tire wear.

Refer to the specification charts.

With tire pressure monitoring system: After adjusting the tire pressure, initialization of the tire pressure monitoring system is necessary to make the system operate normally. Refer to Tire Pressure Monitoring System Initialization.

Always check tire pressure when tires are cold.
Warm tires normally exceed recommended pressures. Do not release air from warm tires to adjust the pressure.
Underinflation can cause reduced fuel economy, uneven and accelerated tire wear, and poor sealing of the tire bead, which will deform the wheel and cause separation of tire from rim.
Overinflation can produce a harsh ride, uneven and accelerated tire wear, and a greater possibility of damage from road hazards.
Keep your tire pressure at the correct levels. If one frequently needs inflating, have it inspected.

WARNING

Always inflate the tires to the correct pressure

Overinflation or underinflation of tires is dangerous. Adverse handling or unexpected tire failure could result in a serious accident.

Use only a Toyota-genuine tire valve cap

Use of a non-genuine part is dangerous as the correct tire air pressure cannot be maintained if the tire valve becomes damaged. If the vehicle is driven under this condition, the tire air pressure will decrease which could result in a serious accident. Do not use any part for the tire valve cap that is not a Toyota-genuine part.

Tires

For reasons of proper performance, safety, and better fuel economy, always maintain recommended tire inflation pressures and stay within the recommended load limits and weight distribution...

Tire Rotation

During rotation, inspect them for correct balance. Also, inspect them for uneven wear and damage. Abnormal wear is usually caused by one or a combination of the following: Incorrect tire pressure Improper wheel alignment Out-of-balance wheel Severe braking After rotation, inflate all tire pressures to specification and inspect the lug nuts for tightness...
