Patent ID: 11554607

Abstract:
A structurally supported non-pneumatic tyre comprises a tread, an annular band, a plurality of spokes extending transversely and radially inside the annular band, and means for connecting the plurality of spokes to a wheel, characterized in that the spokes comprise a polymeric composition based on at least one polymeric matrix comprising 50 to 70% of one or more thermoplastic polymers, the glass transition temperature (Tg) of which is within a range extending from 120 to 250° C. and 30 to 50% of one or more thermoplastic elastomers, said thermoplastic elastomer(s) being compatible with said thermoplastic polymer(s), such that the elongation at break of the mixture of these polymers is greater than or equal to the elongation at break of the thermoplastic polymer(s) alone.
