07 Wheels and tires
General information
NOTE
•
If the tires are rotated, they should only
be moved from front to rear or vice
versa. They should never be rotated left
to right/right to left.
•
Ideally, tire rotation should be done the
first time after approximately 3,000
miles (5,000 km) and thereafter at
6,000-mile (10,000-km) intervals. Some
customers find that tire rotation may
help to get extra mileage from tire life.
•
Tire rotation should only be performed
if front/rear tire wear is fairly even and
tread height is above 1/16" (1.6 mm).
Tread wear indicator
07
The tires have wear indicator strips running
across or parallel to the tread. The letters TWI
272
are printed on the side of the tire. When
approximately 1/16" (1.6 mm) is left on the
tread, these strips become visible and indicate
that the tire should be replaced. Tires with less
than 1/16" (1.6 mm) tread offer very poor trac-
tion.
When replacing worn tires, it is recommended
that the tire be identical in type (radial) and size
as the one being replaced. Using a tire of the
same make (manufacturer) will prevent altera-
tion of the driving characteristics of the vehicle.
