Wheel balancing
The w heels on new ve hicl es a re bala nced. However, v ario us sit uatio ns
dur ing everyday driving can cause them to become unba lanced,

Unbalanced whee ls mus t be rebalanced to avoid excessive wear on
s t eer ing, suspension and t ir e s. A wheel must also b e rebalanced

Safety first
Incorrect wheel alignment
Incorrec t wheel a lignment can c ause excessive t ire wear, im pair ing

& WARNING
Sudden tire failure can lead to loss of control, a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear ind icators .
• Worn tires are a safety hazard, they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control.
• Always keep chemicals that can cause tire damage, such as
grease, oil , gasoline and brake fluid away from tires.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
