Abstract: A pneumatic tire (10) has adjacent carcass plies (13, 14, 15) which are reinforced by cables comprising aramid filaments. The amount of strength retained by the cables over a period of normal use of the tire is increased when for each pair of adjacent carcass plies: (a) the cables of the radially innermost of said carcass plies intersect the mid-circumferential plane (CP) of the tire at a first angle in the range of 75.degree. to 105.degree. and the cables of the radially outermost of said carcass plies intersect the mid-circumferential centerplane (CP) at a second angle in the range of 75.degree. to 105.degree.; (b) said second angle is nearer to 90.degree. than said first angle; and (c) the included angle between said first and second angles is not greater than 10.degree..
