Abstract

A tire (1) is disclosed comprising a tread (20) and a belt portion (100) located radially below the tread (20). The tread (20) has two shoulder portions, each shoulder portion comprising a shoulder groove (21). The belt portion (100) comprises an intermediate belt (120) and a pair of working belts comprising a first working belt (110) and a second working belt (130) arranged radially above the first working belt (130). The intermediate belt (120) is arranged between the first working belt (110) and the second working belt (130) and has elongated reinforcement elements making an angle of less than 5° with a circumferential direction of the tire (1). The intermediate belt (120) comprises a first layer (121) and one or more further layers (122, 123). The first layer (121) of the intermediate belt (120) extends over at least 70% of the axial width of an axially largest working belt (110, 130) of the pair of working belts. Each layer of the one or more further layers (122, 123) of the intermediate belt (120) is arranged radially below one of the shoulder grooves (21) and extends over at most 50% of the axial width of the axially largest working belt (110, 130). The belt portion (100) further comprises a top belt (140) arranged radially above the second working belt (130). The top belt (140) comprises reinforcement cords having an impact energy absorption higher than 7 J/mm<2>.
