General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle.
Tires may be the least appreciated and most
abused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara-
tively small patch of rubber on each tire that
assures that a ll-important contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safely han-
d le, avoiding damage from road hazards and
reg ularly inspect ing t ires for damage includ-
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in-
cluding tread separat ion and blowouts.
Avoiding damage
If you have to d rive over a curb or similar ob-
stacle, drive very slow ly and as close as possi -
ble at a right angle to the curb.
Always keep chemicals includ ing grease, oil,
gasoline and brake fluid off t he t ires .
Inspect the t ires regularly for damage (cuts,
cracks or blisters, etc.). Remove any fo reign
bod ies embedde d in the treads.
Storing tires
Mark tires when you remove them to indicate
the direction of rotation . This ensures you to
be ab le to mount them correctly when you re-
install them .
When removed, the wheels or t ires should be
sto red in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims .

Unidirectional tires
A un idirectional tire can be identified by ar-
rows on the sidewa ll, that po int in the direc-
tion the t ire is designed to rotate. You mus t
fol low the specified di rection of rotation . This
is necessary so that these tires can develop
their optimum characteristics regarding grip,
road noise, wear and hydrop laning resistance.
