Other information:
Tires should be rotated every 12 000 km
(7,500 mi). See Maintenance Schedule.
Tires are rotated to achieve a more
uniform wear for all tires. The first
rotation is the most important.
Anytime unusual wear is noticed, rotate
the tires as soon as possible, check for
proper tire inflation pressure, and check
for damaged tires or wheels...
