Though these tires cost higher than conventional carbon black (CB) based tires, consumer purchases these types of tires due to traction safety and high gas mileage. There were many studies on accelerator effects on vulca-nization properties of CB filled rubber compounds.38,39,42-44 For example, Lorenz and Echte, and Scheele and Cherubim stud-
The vulcanizing accelerator includes but is not limited to N,N-dicyclohexyl-2-benzothiazolsulfene amide DZ, zinc N,N-dibutylcarbamodithioate ZDBC(BZ), and 2,2′-dibenzothiazole disulfide) MBTS(DM). Further preferably, the above radial tire further includes other auxiliary agents such as a scorch retarder.
