Abstract
A strip of rubber base bonding material for use in cold bonding a prevulcanized tread strip to a tire contains both a low-temperature vulcanizing agent and accelerators. The bonding material is compounded by a special technique which stabilizes the vulcanizing agent and the accelerator thereby avoiding prevulcanization during storage. In use the bonding material is interposed between the tread strip and the tire, and the assembly is heated to less than about 300.degree. F under pressure to effect vulcanizing of the bonding material.
