Abstract

Embodiments of the disclosure include a pneumatic tire having improved high speed limits while generally maintaining wear, traction, and handling performance. Said tires include a cap ply extending substantially across a full width of at least one of the belt plies and being arranged at least partially within each shoulder, the cap ply forming a layer of elastomeric material reinforced with a plurality of elongate reinforcements spaced apart in an array, the cap ply being characterized as having a rupture force greater than 210 N per 15 mm of the cap ply width. In each shoulder area of said tires, the tread is characterized as being flatter and having a greater tread thickness.
