III. PREPARATIONS
Tire & Wheel Preparation
Any pneumatic tire can be fl atproofed regardless of pressure or rated load specifi cations. New tires provide
the best long-term value, although used tires are often fl atproofed.
All new tires should be pre-stretched before fi lling. Infl ate new tires to maximum rated infl ation pressure and
maintain overnight. Tires grow during service and pre-stretching allows the tire to be fi lled to its capacity and
will minimize long term carcass growth. Used tires do not need to be pre-stretched and typically take 15-20%
more material than new tires.
Tires, especially used tires, should always be inspected prior to fl atproofi ng. Flat tires should be repaired. To
be effectively fl atproofed, tires must be able to hold air for at least three hours and be free of cuts or other
defects that reduce casing strength.
Wheels should be inspected for cracks, metal fatigue, and corrosion. Damaged or rusted wheels are a safety
hazard and should be avoided.
Tires and wheels have recommended load carrying capacities. The load carrying capacities should not be
exceeded. When calculating the total vehicle weight, take into consideration the extra weight of the fl atproofi ng
material.
A tire or wheel with a defect should not be used in fl atproofi ng, as it could result in a premature tire or wheel
failure. Allow time for drying if washing is required.
Tire contaminants, such as water, sealants, glycol, calcium chloride, soaps, waxes, or even dirt, must be
removed before fl atproofi ng.
For tube type tires, always use new properly sized tubes. Wheels that require the use of fl aps to protect the
tube during infl ation and operation must be fi lled with the fl ap in place. If you remove the fl ap, the tube has a
greater chance of rupturing during the fl atproofi ng and curing process.
Tire and wheel assemblies should be at a minimum of 72˚ F (22˚ C) before processing. Cold tires will slow the
curing process.
Equipment Set-up
1. Arrange Totes and
Drums – Totes should
be arranged with the
ISO-side on the left and
the CAT-side on the right.
The lower cylinders of
the pump are labeled
as to which hose goes
to which side. When
moving the pump, be
sure to keep tote hoses
on their proper side.
It is a good idea to
place roofi ng felt in the
pumping area, especially
under the tire being fi lled,
for easier clean-up.
