Check the condition of your tires each day
before you ride. Replace tires if tires show
visual evidence of damage, such as cracks
or cuts, or if tread depth is less than 1.6 mm
front, 1.6 mm rear.
NOTE: The "Triangle" mark indicates the
place where the wear bars are molded into
the tire. When the wear bars contact the
road, it indicates that the tire wear limit has
been reached.
Whenever you replace a tire, use a tire of
the size and type listed below. If you use a
different size or type of tire, vehicle handling
may be adversely affected, possibly result-
ing in loss of vehicle control.
