The invention relates to a tyre, the aspect ratio H/L of which is strictly greater than 0.75, comprising a crown reinforcement (4) made up of two working crown layers (41, 42) of reinforcing elements. According to the invention, the two working crown layers (41, 42) are only present to form the crown reinforcement (4) over at least 40% of the width of the tread (5), the absolute value of the difference between the absolute values of the angles a2 and a1 being greater than 9°, a2 being greater than a1 in absolute terms, the average angle a satisfying the relationship 14+131 *exp(-L/100) < a < 20+164 *exp(-L/100), and the utilization ratio of the breaking potential F2/FR2 of the radially outermost working layer (42) being less than 1/6.
