1. A method for repairing a tire comprising:
(a) providing a reamer, an insertion tool, a rubber tri-layer strip, and vulcanizing fluid;
(b) inserting the reamer into a puncture hole of the tire configured to clear the puncture hole of any debris and to generate rougher surface to increase surface area within the puncture hole to receive and bond the vulcanizing fluid;
(c) applying the vulcanizing fluid to the puncture hole and the tri-layer strip;
(d) inserting the tri-layer strip into the receiving opening of the insertion tool;
(e) inserting the insertion tool with the tri-layer strip into the puncture hole to cause the tri-layer strip to fold into the puncture hole mixed with the vulcanizing fluid to bond the tri-layer strip and the tire; and
(f) removing the insertion tool from the puncture hole causing a center portion of the tri-layer strip to fold forming a four-layer seal within the puncture hole;
wherein the vulcanizing fluid causes an immediate reaction to bond the tri-layer strip to the tire;
wherein the tri-layer strip comprises a first layer and third layer formed of a soft vulcanized rubber; a second layer formed of a tensile rubber configured to structurally support the first layer and third layer and provided there between; and
wherein the first layer and third layer react with the vulcanizing fluid to form a permanent bond between the tri-layer strip and the tire.
