Beschreibung
Zusammenfassung:	A pneumatic tire having gum strips (19,21) for encapsulation of the cut edge of a cord reinforced ply (14), in particular a carcass ply. The gum strips are formed from an elastomeric compound having physical properties such that its 300% Modulus (ASTM D412) is comprised between 5 and 7 MPa and its Shore A Hardness (ASTM D1415) is comprised between 55 and 65. It has been found that such gum strips when used in the bead portion (11) of a tire to encapsulate the ply end (18), improve the durability of the tire.
