Tire Inflation Pressure

Maintaining the specified tire air pressure provides the best combination of vehicle handling, tire durability and ride comfort.

Low tire air pressure causes rapid and uneven tread wear, degrades vehicle handling, increases fuel consumption and, in addition, makes tire failure due to overheating more likely.

Tires with excessively high air pressure reduce ride smoothness and are more susceptible to damage from impacts with road obstacles, potholes and the like. In addition, excessively high tire pressure causes uneven tread wear.

We recommend visually checking the tire air pressure daily. If you determine by sight that the tire pressure has decreased, check the air pressure immediately with a tire pressure gauge.

Check the air pressure in all tires with a tire pressure gauge at least once a month. Even in fully serviceable tires, air pressure may drop by 10 to 20 kPa (0.1 to 0.2 kgf/cm²) over a month.

Do not forget to check the air pressure in the spare tire at the same time as the other tires.

Check the tire air pressure only when the tires are cold. Tires can be considered cold if at least three hours have passed since the vehicle was stopped, or if after a long period of parking you have driven no more than 1.6 km. Inflate the tire or, if necessary, release some air to bring the pressure to the value specified on the label attached to the driver's side door pillar.

After driving the vehicle a distance of several kilometers, the tires warm up and their air pressure increases by 30 to 40 kPa (0.3 to 0.4 kgf/cm²) compared with the cold state. This is not a sign of a malfunction. Do not reduce the air pressure in warm tires to the value specified for cold tires. Otherwise, the tires will be operated at reduced air pressure.

You should purchase and keep in the vehicle your own tire pressure gauge, which you should use consistently when checking tire air pressure. This way you will be able to notice a tire malfunction in time: a small detected drop in tire air pressure can be attributed with high confidence to tire damage rather than to differences in gauge readings.

Although tubeless tires have a certain ability to retain air after small punctures, carefully inspect them when pressure loss occurs, paying attention to punctures and foreign objects embedded in the tread.

For your convenience, a label showing the tire size and the recommended cold tire inflation pressure is attached to the driver's door pillar.
