WARNING
The traction grade assigned to this
tire is based on straight-ahead
braking traction tests, and does
not include acceleration, corner-
ing, hydroplaning, or peak traction
characteristics.
These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicle
may vary with respect to grade.
