Tyres and wheels
Tyres should be replaced when tread
wear indicators appear. Slow down
whenever there is rain, snow or ice on
the road to reduce the possibility of los

ing control of the vehicle.
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.
