Abstract
A pneumatic tire includes an internal sealing layer, which partially delimits an internal volume of the pneumatic tire, and a self-sealing layer formed of a self-sealing product. The self-sealing layer is positioned radially on an inside region with respect to the internal sealing layer, and has a creep resistance indicator that decreases radially outwards, i.e., towards outside of the pneumatic tire.
