Abstract
A tire tread incorporating an elastomeric composition reinforced with silica, based on at least (phr=parts by weight per hundred parts of diene elastomer): Preferably, this LS 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' reinforced with a silica of higher specific surface area, the tread of the invention has an improved compromise of performances in terms of wear resistance, rolling resistance, grip and drift thrust.
