Tire with circumferential rubber tread having a lateral outboard control element

摘要

The invention relates to a tire having a circumferential tread (2) of a cap/base configuration composed of an outer tread rubber cap layer with a running surface of the tread and an underlying tread rubber base layer (3), wherein said tread cap layer (3) is composed of two longitudinal adjacent zones (11, 12), namely a primary tread cap zone (11) and a minor lateral outboard control element (12). The primary tread cap zone (11) and the lateral outboard tread cap element (12) provide a significant gradation of cold dynamic storage moduli (G') at -25°C and hot tan delta values at 100°C, yet similar warm dynamic storage moduli (G') at 60°C.
