-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age.
(D Note

tires are designed for the cond itions that

radio, and heater, to the extent that these
items are availab le as factory-installed equip­
ment (whether installed or not).
A spect ratio
means th e ratio of the height to the width of
the tire in percent. Numbers of 55 or lower in­
d icate a low sidewall for improved steer ing re­
sponse and better overall handling on dry
pavement .
Bead
means the part of the tire th at is made of
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the rim.
Bead s eparation
means a breakdown of the bond between
components in the bead.
Cord
means t he strands forming the plies in the
tire. ter months.
Low tempe ratu res signifi­
cantly decrease the elasticity of summer
tires, which affects traction and braking ability. If summer tires are used in very
co ld temperatures, cracks can form on
the tread bars, resu lting in permanent
tire damage that can cause loud driving
noise and unbalanced tires. Aud i is not
responsib le for this type of damage.
- Burn ished, polished or chromed rims
must not be used in winter weather. The
surfa ce of the rims does not have suff i­
c ien t cor rosion prote ct io n for this and
co uld be pe rmanen tly damaged by road
salt or simi lar substances. This damage
is not cove red by war ranty.
Cold tire inflat ion pre ssure
mea ns the t ire press ure recommended by the

size that has not bee n driven for more than a

standard equipment including the maximum
capacity of fuel, o il, and coolant, air condi­

and at higher inflation pressures than the cor­
responding standard tire. Extra load tires may
be identified as "XL", "xl", "EXTRA LOAD", or
"RF" on the sidewall.
Gross A xle Weight Rating ("GAWR")
means the load-carrying capacity of a single
