An air spring bellow formed from a rubber composition including a rubber component that contains a polyisoprene rubber and syndiotactic 1,2-polybutadiene. The syndiotactic 1,2-polybutadiene has a low crystallinity of 40 percent or less and the rubber composition includes a filler. L'invention concerne un soufflet de suspension pneumatique formé à partir d'une composition de caoutchouc comprenant un composant caoutchouc qui contient un caoutchouc polyisoprène et du 1,2-polybutadiène syndiotactique. Le 1,2-polybutadiène syndiotactique présente une faible cristallinité inférieure ou égale à 40 pour cent et la composition de caoutchouc comprend une charge.
