Airplane tire with a tread wear indicator, with a circumferential ridge (4) of the tread (2) having an initial height H0 and an allowable remaining height HR. Wear indicator (6) comprises N cylindrical cavities (7) emerging on rolling surface (3) and independent of one another. The N cavities are divided into a first family of N1 wear cavities C1i (8) having respective initial depths P1i in pairs that are distinct and equal to i*(H0−HR)/N1, i being an integer number varying from 1 to N1, and into a second family of N2 positioning cavities C2j (9), j being an integer number varying from 1 to N2, each positioning cavity C2j having an initial depth P2j strictly greater than (H0−HR), such that only the N2 positioning cavities C2j (9) emerge on rolling surface (3) when height HR of circumferential ridge (4) is reached.
