Wear Indicators; Tyre Service Life - Honda CIVIC 2014 Manual

• Cracks or other damage around valve stem.
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 (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 calibrate the deflation warning system.
2 Deflation Warning System P. 249
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.

Tyre Service Life

The life of your tyres is dependent on many factors, including driving habits, road conditions,
vehicle loading, inflation pressure, maintenance history, speed, and environmental
conditions (even when the tyres are not in use).
WARNING

The groove where the wear indicator is located is about
1.6 mm (about 1/16 inch) shallower than elsewhere on
the tyre. If the tread has worn so that the indicator is
exposed, replace the tyre.
Worn out tyres have poor traction on wet roads.
