Tips on Installing Tire Guards

How does a tire guard work?
Tire guards are inserted inside tires to protect tire tubes. When an object like
a bolt, nail, screw, etc., punctures the tread of a tire with a properly installed
tire guard, the object will strike the tire guard instead of the tube. Since the
guard is not part of the tire, it can move toward the tube and resist the object.
The intruding object will tend to move to the side or be forced out of the tire.
NOTE:  Tire guards are not to be used on the highway or at high speeds.

Example of Tire Guard

Gathering important information

Because tire sizes vary from manufacturer to manufacturer, our tire guard manufacturer needs
to know some information about your tires in order to build the tire guards.

1.  Tire Manufacturer

The name of the tire manufacturer is usually displayed on the side of the tire,
as shown in the examples below.

Carlisle Tire
Titan Tire
Nanco Tire

2.  Tire Size

The examples below show the tire size for three different tires along with a picture that
depicts where that tire size was found on the tire itself. For instance, in the first example,
the tire size "18 x 8.50 - 8" describes a tire that has an outside diameter of 18 inches,
a tread width of 8.50 inches, and an inner rim diameter of 8 inches.

Tire size: 18 x 8.50 - 8
18 x 8.50 - 8
Tire size: 4.10 - 4NHS
4.10 - 4NHS
Tire size: 20 x 10.00 - 8
20 x 10.00 - 8

Step-by-step installation process

Important note:  Before installing a tire guard, always check inside the tire to make
sure there are no objects or debris.
Tire Guard   
1.  The tire guard has a flat side (tube side) and a beveled
edge side (tire side). The beveled edge gives a smoother fit
in the shoulder area to help prevent tube chafing.

the tire guard is 1/2" thick.
Insert Tire Guard into Tire   
3.  Squeeze the tire guard together and insert it in the tire.
Tire Guard to Bottom of Tire   
4.  Push the tire guard to the bottom of the tire.
Remaining Gaurd into Tire   
5.  Squeeze the remaining tire guard together and push
it inside the tire.
Loop End Inside the Tire Beads   
6.  With the tire guard inside the tire, push the loop
end inside the tire beads.
Half Guard in Bead Area   
7.  With half the guard in the bead area, push the remaining
half into the tire.

8.  With
just a large
loop left,
push on the center of the loop.
Bulge in Tube   
9.  If there is a bulge or small loop left after pressing several times
in different areas, then the guard is too large in circumference for
the tire. Alternatively, if the guard fits in the tire, but there is
enough space left over for the guard to be moved up and down,
then the guard is too small in circumference for the tire. If the
guard does not fit correctly, it will cause a tube failure. For more
information, call our technical service department
at 1-800-874-4755.
Correct Fit Inside Tire   
10.  When the tire guard fits correctly inside the tire, the tire
guard will lay flat all the way around the inside of the tire.
The fit should be snug, yet there should be no bulges or
loops in the tire guard.
Tire Talc 11.  Apply a coat of the tire talc #63 to the tire guard
before installing the tube to help reduce chafing.
