1-16. (canceled)
A tubeless tyre having a shape of a torus open radially inwards with an outer wall and an inner wall, wherein at least part of the inner wall is covered with a self-sealing layer that includes a thermoplastic styrene (TPS) elastomer having a Shore 0 hardness of less than 35.
A tubeless tyre having a shape of a torus open radially inwards with an outer wall and an inner wall, wherein at least part of the inner wall is covered with a self-sealing layer that includes a thermoplastic styrene (TPS) elastomer having a dynamic modulus G* of less than 0.01 MPa, and wherein the dynamic modulus G* is measured at a frequency of 10 Hz and a temperature of 60° C.
A method of applying a self-sealing laminate to an internal wall of a cycle tyre, the tire being a tubeless tyre having a shape of a torus open radially inwards with an outer wall and an inner wall, wherein at least part of the inner wall is covered with a self-sealing layer that includes a thermoplastic styrene (TPS) elastomer having a Shore 0 hardness of less than 35 or that includes a thermoplastic styrene (TPS) elastomer having a dynamic modulus G* of less than 0.01 MPa, the dynamic modulus G* being measured at a frequency of 10 Hz and a temperature of 60° C., the method comprising:
- turning the tyre inside out so as to bring the inner wall to face outside of the torus and to bring the outer wall to face inside of the torus;
- extending the outer wall of the tyre;
- applying a self-sealant to the inner wall of the tyre;
- and
- turning the tyre inside out so as to return the inner wall to face the inside of the torus and to return the outer wall to face the outside of the torus.
