Cornering wear can be most easily distinguished from
abnormal camber wear by the rounding of the outside
shoulder or edge of the tire and by the roughening of the
tread surface which denotes abrasion.
Cornering wear often produces a fin or raised portion
along the inside edge of each row in the tread pattern.
In some cases this fin is almost as pronounced as a toe-
in fin, and in others, it tapers into a row of tread blocks
to such an extent that the tire has a definite "step wear"
appearance.
The only remedy for cornering wear is proper instruc­
tion of operators. Driving more slowly on curves and
turns will avoid grinding rubber off tires.
mal cornering wear as much as possible, tires should be
interchanged at regular intervals.

Wheel and Tire Balancing
It is desirable from the standpoints of tire wear and
vehicle handling ease to maintain proper balance of front
wheel and tire assemblies on all models. All wheels in­
tended for use on front of vehicle, such as those switched
during periodic tire rotation and those installed as new or
repaired replacement equipment should be accurately
balanced. This may be accomplished by either of the two
types of balancing systems in current use which balance
wheels either on the vehicle or off.
type, however, is the more desirable in that all rolling
components (brake drums, bearings, seals, etc.) are in­
cluded in the balancing procedure and thereby have any
existing unbalance corrected.
