NOTE: If a seal cannot be effected in the foregoing manner with
the rush of air, it can be accomplished by applying a mounting
band or heavy sash cord to the circumference of the tire and then
tightening with a tire iron.
Repairing Tubeless Tires
There are several methods of repairing tubeless tires advo-
cated by the tire manufacturers, all of which are based on
their combined experience. Methods which have proven very
satisfactory for repair of punctures not exceeding 3/16" diam-
eter are outlined in this section, while repair procedure for
punctures in excess of
3/
16" are not herein covered due to
the wide variance in the type of repair required for injuries
of this
magnitude.
Chevrolet recommends the use of either of two types of
patches for repair of tubeless tires. Both types are currently
available from the tire manufacturers and are merchandised
in kits which also contain the necessary hand tools and other
material for a complete tire repair job.
The recommended patch types are:
1. The Self-Vulcanizing Cold
Patch.
No heat is required in the use of this patch as vulcaniza-
tion is chemically performed upon application of the
patch.
This type of patch has been found to give excellent results
on all standard production type tubeless tires, but should
under no circumstance be used on puncture sealing tires in-
corporating a soft sealant material in the inner liner.
2. The Hot Patch.
This patch contains its own fuel and vulcanization takes
place when this fuel is
ignited.
Previous experience has shown
this type patch to be very satisfactory for repair of all types
of tubeless tires.
Prior to the application of either of the above mentioned
patches the tire injury must first be cleaned and filled as
described in the following paragraphs:
