Tyre traction
Tyre traction can be reduced if you drive
on worn tyres, tyres that are improperly
inflated or on slippery road surfaces.
Tyres should be replaced when tread
wear indicators appear. To reduce the
possibility of losing control, slow down
whenever there is rain, snow or ice on
the road.

A tyre’s sidewall is marked with a tyre

information when selecting replacement
tyres for your car. The following explains
what the letters and numbers in the tyre
size designation mean.
Tyre maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease tyre
wear. If you find a tyre is worn unevenly,
have your dealer check the wheel
alignment.
When you have new tyres installed,
make sure they are balanced. This will
increase vehicle ride comfort and tyre
life. Additionally, a tyre should always
be rebalanced if it is removed from the
wheel.

This information identifies and describes
the fundamental characteristics of
the tyre and also provides the tyre
