balance of the wheels and tires and alignment of the front axle are

CARE OF TIRES
The condition of the tires on your truck should be one of your great-
est concerns. Today's tires, if given reasonable care, will give you
many thousands of miles of trouble-free service. But if you abuse
them, they may fail you prematurely.

kept tight on all tires. .
If the front and rear tires on your truck are the same size, it is
recommended that you rotate them about every 3,000 miles for
maximum tire life. It is not necessary to remove the tire from the rim,
but rotate the complete wheel-and-tire.
It is important that the wheel lock nuts be checked for looseness at
regular intervals. They must be kept tight at all times. Also when the
wheels are removed and installed the lock nuts must be tightened
as tightly as possible with the special wrench furnished for that
purpose. The wheel lock nuts should be tightened to a torque of
375 to 425 foot-pounds.

the other wheels to prevent possible movement of the truck.
2. Raise wheel off the ground, using a jack.
3. Remove the nuts from the studs which hold the wheel to the hub.
4. Lift the wheel off the hub.
5 . Make sure all air is removed from the inner tube. Loosen the
casing from the rim by stepping on the sides as shown in the
illustration. If the truck is equipped with safety-rim wheels,
it is necessary to snap the tire bead over the bead lock. This
can be done by using the truck jack to bring the weight of the
vehicle to bear on the side of the tire.
