1. What is a tire reliner?
A tire reliner is two half-moon-shaped pieces (although some smaller sizes may be a single piece) of tire material that are placed between the inside of the tire and the inner tube to help prevent flats from thorns, roadside debris or stubble.


2. What are some features of a tire reliner?
The reliner is roughly 1/4" thick and adds between 4- and 6-ply of cord material to the inside of a tire. A reliner covers the tread area of the tire and to within an inch or two of the tire bead.


3. How are tire reliners installed?
With the tire dismounted from the vehicle and wheel, you simply squeeze one piece of the reliner together and slide it into the tire and repeat the process with the second piece, making certain to lap one end over and one end under for the best fit. You put the inner tube into the reliner and inflate it; the pressure of the inflated inner tube holds the reliner in place. For additional protection, you can encase the good tube in an old one of the same size with the valve stem cut off and split down the inside of the circumference to help reduce chafing.


4. What is a spot reliner?
A spot reliner is a single piece of tire material that can be used to provide additional protection to the inner tube in the damaged area of the tire after it has been repaired, extending the service life of the damaged tire.


5. What are some features of a spot reliner?
The spot reliner is about 1/4" thick and cut to be compatible with specific tire cross sections or widths. It is feathered along the edges to reduce chafing and adds between 4- and 6-ply of protection to the impacted area of the tire.

6. How is a spot reliner installed?
After a repair boot has been installed over the wounded area on the inside of the tire, the spot reliner should be placed in that specific location between the inside of the tire and the inner tube. The pressure from the inflated tube will hold the spot reliner in place. For additional protection, you can encase the good tube in an old one of the same size with the valve stem cut off and split down the inside of the circumference to help reduce chafing.


7. What is a tire guard?
A tire guard is a single piece of rubber tire material designed to fit in tires of a specific size, brand and tread design (that information is needed when ordering to insure proper fit) to protect the inner tube from objects that could puncture it. The guard is installed between the inside of the tire and the inner tube, and the custom-made tire guard helps protect the tube from nails, screws, glass, thorns, staples, or other sharp object that can push through the tire and puncture it.


8. What are some features of a tire guard?
A tire guard is about 1/2" thick through the cross section area and tapers off thinner along the sides, adding at least 6-ply of material to the inside of the tire. A tire guard provides excellent protection to the tread area of the tire and to a lesser extent along the sidewall area.


9. How are tire guards installed?
With the tire dismounted from the vehicle and wheel, you squeeze the tire guard together and insert it into the tire, push the guard to the bottom of the tire, and squeeze the remaining tire guard together and push it inside the tire.  With the guard inside the tire, you push the loop end inside the tire beads, and, with half the guard in the bead area, push the remaining half into the tire.  When the tire guard fits correctly, it will lay flat all the way around the inside of the tire; the fit should be snug but without bulges or loops in the tire guard.  The pressure from the inflated tube will hold the tire guard in place.  For additional protection, you can encase the good tube in an old one of the same size with the valve stem cut off and split down the inside of the circumference to help reduce chafing.

10. How are tire reliners different from tire guards?
Tire reliners are generally two pieces of tire cord material, while tire guards are a single, continuous piece. One set of reliners can fit in multiple sized tires, while tire guards are custom-made to fit in a tire of a specific size, brand and tread type. Tire reliners provide good protection to the tread and sidewall areas of a tire, while tire guards offer outstanding protection in the tread area but less so in the sidewall.

11. Can reliners or tire guards be used in tires of vehicles that travel on the highway or at high speeds?
No. Reliners – both full tire and spot – and tire guards are designed to be installed in the tires of vehicles that travel off-road and at speeds of 25 mph or less.
