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
G021829
The tires have wear indicator strips running
across or parallel to the tread. The letters TWI
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.
