 CASINGS
It's Really Easy if Everyone
is
on the Same Page
One of the great and totally unnecessary sources of
misunderstanding between casings supplies and retreaders is a simple
definition of terms.
The buyer will order an A grade casing.
The seller will have one specification in mind, while the seller
will have something quite different in mind. So when the container
arrives, the problems begin.
In order to avoid any such misunderstandings, we put our
specifications in writing. This saves a lot of trouble in the long
run and helps us make friends for many years to come.

Resource Conservation
It takes about 22 gallons of oil to produce one truck tire and
just 7 gallons to retread the same tire. This means 15 gallons of
oil are saved each time a truck tire is recycled. Retreading
conserves 400 million gallons of oil annually in the United States
and Canada. |

Ecology
Retreaded tires contain 75 percent post consumer recycled materials,
one of the highest percentages of all recycled products. Since the
casing already has undergone one life cycle, the only new material
used to retread a tire is the raw material used to manufacture the
tread. In 1992, 33 million tires were retreaded in North America and
placed back in service rather than further contributing to the solid
waste stream.

Tire Care
Valves
New valve stem, core and cap are recommended for all new tubeless
tires.
Lubricant
Tire beads and rim flanges should be treated with a recommended
lubricant inside and out. Beads should be lubricated both during
mounting and dismounting (in case you wish to remount the tire and
also to protect the wheel from damage).
Do not, under any circumstances, use liquids such as oil, gasoline,
spirits, or water.
Tire Rotation
Tire rotation is vital to achieving even tread wear and long tread
life. Rotation is necessary because of the uneven wear characteristics
of each wheel position on the vehicle. A good example is Front Wheel
Drive vehicles which places braking, steering and driving forces on
the front axle tires. Rear axle tires only receive braking forces
resulting in a much faster wear rate for the front axle tires. Tire
rotation for these vehicles therefore becomes very important for
optimum tire life. |
