Abstract
The tire has a load index that is at least 118 and two layers of reinforcing elements. Each of the layers has a breaking force per unit width that is higher than 2900 daN/dm. A minimum strength per unit width, measured for an elongation of less than 10%, of the second layer is greater than 20% of the minimum strength per unit width, measured for an elongation of less than 10%, of the first layer. The reinforcing elements of the first layer have a thread count that is higher than 300 tex. The reinforcing elements of the two layers have a thread count of less than 750 tex. The elongation of the reinforcing elements of the second layer are greater than 8% under a force of 20 daN and the secant elastic modulus values under tension at 10% elongation, Mt, Mj, satisfy the relationship Mt/Mj≥1.
