Abstract
A tire with a built-in self-sealing layer includes an external rubber tread, a carcass reinforcer, a gastight layer arranged towards an inside location relative to the carcass reinforcer, an anti-tack layer arranged furthest towards the inside, location and a self-sealing layer adjacent to the anti-tack layer and arranged towards the inside location relative to the gastight layer. The anti-tack layer includes particles with a shape factor (F=L/E) higher than 5. L represents a first dimension, and E represents a second dimension normal to the first dimension, with L being a longer dimension than E.
