Wheels
-Have the wheels rebalanced if an
imbalance is causing noticeable
vibration in the steering wheel.
If you do not, the tires and other
vehicle components
could wear
more quickly.
Treadwear indicator
The original tires on your vehicle
have 1/16 inch (1 .6 mm) high
"wear indicators" ¢ fig. 191 run-
ning across the tread. Marks on
the tire sidewall (for example
"TWI" or other symbols) indicate
the positions of the tread wear in-
dicators.
The tires have reached the mini -
mum tread depth
l)
when they
have worn down to the treadwear
indicators. Replace the tires with
new ones¢ .&. .
Tire rotation
Rotating the tires regularly is rec-
ommended to ensure the tires
wear evenly . To rotate the tires,
install the tires from the rear axle
on the front axle and vice versa.
This will allow the tires to have
approximately
the same length of
service life.
