Checking and Maintaining Tyres

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.

■

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 energy 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. Even tyres in good condition can lose 10–20 kPa (0.1–0.2 bar, 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.

2

Wear Indicators

 P. 610

•

Cracks or other damage around valve stem.

1

Checking Tyres

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 (1 mile). 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 bar, 4–6 psi) higher than if 
checked when cold.

Whenever tyre pressure is adjusted, you must 
initialise the deflation warning system.

2

Deflation Warning System

 P. 420

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.

3

WARNING

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.
