Checking Tyres

To safely operate your vehicle, your tyres must be of the proper type and size, in good condition with adequate tread, and properly inflated.

Using tyres that are excessively worn or improperly inflated can cause a crash in which you can be seriously hurt or killed.

Follow all instructions in this owner's manual regarding tyre inflation and maintenance.
Measure the air pressure when tyres are cold. This means the vehicle has been parked for at least three hours, or driven less than 1.6 km. If necessary, add or release air until the specified pressure is reached.
If checked when hot, tyre pressure can be as much as 30-40 kPa (0.3-0.4 kgf/cm2, 4-6 psi) higher than if checked when cold.
Have a dealer check the tyres if you feel a consistent vibration while driving. New tyres and any that have been removed and reinstalled should be properly balanced.

Inflation guidelines

Properly inflated tyres provide the best combination of handling, tread life, and comfort. Refer to the driver's doorjamb label for the specified pressure.

Underinflated tyres wear unevenly, adversely affect handling and fuel economy, and are more likely to fail from overheating.

Overinflated tyres make your vehicle ride harshly, are more prone to road hazards, and wear unevenly.

Every day before you drive, look at each of the tyres. If one looks lower than the others, check the pressure with a tyre gauge.

At least once a month or before long trips, use a gauge to measure the pressure in all tyres, including the spare. Even tyres in good condition can lose 10-20 kPa (0.1-0.2 kgf/cm2, 1-2 psi) per month.

Inspection guidelines

Every time you check inflation, also examine the tyres and valve stems.
Look for:
  • Bumps or bulges on the side or in the tread. Replace the tyre if you find any cuts, splits, or cracks in the side of the tyre. Replace it if you see fabric or cord.
  • Remove any foreign objects and inspect for air leaks.
  • Uneven tread wear. Have a dealer check the wheel alignment.
  • Excessive tread wear.
  • Cracks or other damage around valve stem.
