TUBE REPAIR
The cold patch method of repairing tubes has proven to be
unsatisfactory for synthetic tubes. When tube repair is necessary
they should be
vulcani~ed
accorcing to the procedure prescribed
for synthetic tubes.
MOUNTING SYNTHETIC TIRES AND TUBES
1. Clean inside of casing thoroughly .
2. Insert tube in tire and inflate until it is nearly rounded out.
3. Inspect wheel rim for rust scale, roughness or bent flanges.
Clean and straighten wheel if necessary.
4. Using a brush or cloth swab, apply a film of neutral veg-
etable oil soap to the inside and outside of tire beads and also to
the rim side of tube. Do not allow soap solution to run down
into tire.
5. Place the tire and tube on the wheel according to standard
procedure. Center the tire on wheel so that beads are out of rim
well before inflating.
6. Center tire valve and pull it firmly against the wheel. Hold
valve in position and inflate tire to recommended pressure while
watching to see that beads of tire are forced out evenly against
wheel flanges.
7. Completely deflate tire by removing valve core. Install core
and reinflate to recommended pressure.
NOTE: The lubrication of tire beads and tube, and the inflation, defla-
tion and reinflation of assembly is most important: If this is not dane the
tube will be stretched e><cessiv .. ly at the bead sides and drop center of
wheel which will cause premature failure.
