  "textContent": "A tire (1) is disclosed comprising one or more tire components, the one or more tire component(s) comprising a rubber formulation comprising a rubbery polymer and from 30 phr to 80 phr of a benzoxazine resin. Also, a rubber composition is disclosed comprising a polydiene rubber, from 30 phr to 80 phr of a benzoxazine resin, and at least 30 phr of silica or of pretreaded silica, wherein said rubber composition is void of isoprene containing polymers. Finally, a method of making a rubber composition is disclosed, the method comprises: (i) reacting, in a first step, a diphenol with an amine, in particular a primary amine, in the presence of an aldehyde derivative, preferably formaldehyde, to obtain a benzoxazine, wherein the diphenol comprises a bridge linking or connecting both phenol groups of the diphenol, and wherein said bridge is connected at at least one of its respective ends to a meta position of the respective phenol group; (ii) mixing an elastomer and a filler in a second step; (iii) adding the benzoxazine in a third step including the option that the mixing of step (ii) continues while adding the benzoxazine in step (iii); and (iv) curing the rubber composition.",
