Difference Between Tire Reliners & Guards
What is the difference between tire reliners and tire guards?
While they both protect tube-type tires against punctures, tire reliners and tire guards do the job a little differently. Tire reliners are two half-moon pieces of rubber tire material (although ones for smaller tires may be one piece), while tire guards are a continuous single piece of cord material.
Tire reliners are placed between the inside of the tire and the inner tube and, they are roughly 1/4-inch thick, adding between 4- and 6-ply to the tire thickness. A reliner protects the tread area of the tire and up the sidewall to an inch or two of the bead. A set of reliners can fit several different sized tires.
Tire guards also go between the inside of the tire and the tube to protect against puncture wounds, and they are about 1/2-inch thick. They add at least 6-ply to the tread area of the tire but provide little to no protection in the sidewall. Tire guards are custom-made to go in a tire of a specific size, brand and tread type, and this information is needed for the vendor to make the tire guard.
