Abstract:
A tire comprising an overlay ply wherein (i) the shoulder section of the overlay comprises an elastomer and short polymeric or non-polymeric reinforcing fibers present in an amount of from 0.1 to 10 parts fiber per hundred parts of elastomer, the short fibers having a tenacity of at least 2 grams per dtex, a modulus of at least 10 grams per dtex and a length of from 0.1 to 8 mm and wherein the fibers are aligned substantially parallel to each other in a controlled angle of orientation within the overlay wherein the orientation is selected such that it decreases tire noise, and (ii) the section of overlay in the crown of the tire comprising cords of continuous filament polymeric fibers or continuous strands of metal or combinations thereof, the cords being aligned in a circumferential direction around the tire.
