Abstract
A tire tread incorporating an elastomeric composition reinforced by an inorganic filler, based on at least: Preferably, this silica furthermore has a disagglomeration rate α greater than 5×10μm/min (measured in the ultrasound disagglomeration test). Compared with a conventional tread for 'Green Tires' which is reinforced with a silica of higher specific surface area, the tread of the invention has an improved compromise of (wear resistance/rolling resistance/grip on wet ground) performances. The use of a very small amount of zinc makes it possible to overcome an increase in the induction delays during the vulcanization, when such a silica of low specific surface area is used.
