Large truck tires are required to operate at high loads and high speeds. As a consequence, the excessive running temperatures lead to reversion in compound components, which may, in turn, lead to reduced tire durability. This article reports laboratory results concerning modification to truck and off-the-road (ORT) tread compounds, with special reference to the antireversion agent 1,3 bis(citraconimidomethyl)benzene (Perkalink 900), aimed at maintaining dynamic mechanical properties following overcure or aging. Perkalink 900 significanly improves reversion resistance by means of a crosslink compensation mechanism: the replacement of reverted polysulphidic crosslinks by thermally stable crosslinks based on a carbon-carbon structure. Crosslink density measurements provide evidence for this. The antireversion agent in combination with the saline coupling agent (TESPT) at a reduced level in the silica containing OTR compound give improved performance with regard to the stability of viscoelastic properties, blow-out resistance and reversion resistance at no cost penalty.
