Tips on Installing Tire Guards

How Does a Tire Guard Work?
Gathering Important Information
Step-by-Step Installation Process


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.

Tire Guard Example

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.

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

    Carlisle, Titan, Nanco
  • 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.
    18 x 8.50 - 8, 4.10 - 4NHS, 20 x 10.00 - 8
    For more information about measuring tire size, see the GEMPLER'S Web page titled How to Measure Tires and Rims.

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.

Step 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.
Step 2 The cut away views show the tire
guard is 1/2" thick.
Step 3 Squeeze the tire guard together and insert it in the tire.
Step 4 Push the tire guard to the bottom of the tire.
Step 5 Squeeze the remaining tire guard together and push it inside the tire.
Step 6 With the tire guard inside the tire, push the loop end inside the
tire beads.
Step 7 With half the guard in the bead area, push the remaining half into
the tire.
Step 8 With just a
large loop
left, push on
the center of
the loop.
Step 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.
Step 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.
Step 11 Apply a coat of the tire talc #63 to the tire guard before installing
the tube to help reduce chafing.
