摘要： Tubeless tire, adapted to be inflated with an inflation gas, comprising: a crown (25) comprising a crown reinforcement (80, 90) surmounted by a tread (40); two sidewalls (30) extending the crown radially inwards; two beads (20) radially inside the sidewalls and each comprising a annular reinforcement structure (70); a carcass reinforcement (60) anchored in each of the beads; an inner-liner (50) impermeable to the inflation gas, covering the inner surface of the tire; wherein, in each sidewall of the tire, the inner-liner comprises at least one slit (200), situated radially between the annular reinforcement structure that is radially outermost, and the radius RE at which the carcass reinforcement, when the tire is fitted to the rim and inflated to its operating pressure, has its largest axial width, the slit having a maximum radial height HR of between 0.5 and 5 mm and extending over at least half of the circumference of the tire. Also disclosed is a process for manufacturing such a tire.
