Life of tires
The service life of a tire is dependent upon
varying factors including but not limited to:
ț driving style
ț tire pressure
ț distance driven
Direction of rotation
Unidirectional tires offer added advantag-
es, such as better hydroplaning perfor-
mance. To benefit, however, you must
ensure that the tires rotate in the direction
specified.
An arrow on the sidewall indicates the in-
tended direction of tire rotation.
Checking tire inflation pressure
Correct the tire pressure only when tires
are cold.
Regularly check your tire pressure at inter-
vals of no more than 14 days.
If the tires are warm, you should only cor-
rect the tire pressure if it is too low for cur-
rent operating conditions.
A table on the fuel filler flap lists the spec-
ified tire inflation pressures for warm and
cold tires as well as for various operating
conditions.
Warning! G
Tires and spare tire should be replaced after
six years, regardless of the remaining tread.
!
Keep unmounted tires in a cool, dry
place with as little exposure to light as
possible. Protect tires from contact
with oil, grease and gasoline.
Warning! G
If the tire pressure repeatedly drops:
ț Check the tires for punctures from
foreign objects.
ț Check to see whether air is leaking from
the valves or from around the rim.
