A pneumatic tire (1) having a rubber insert (7,8) located between a radially outer tread (6) and a radially inner bead core (2). Such insert may, for example, be an apex (7) extending radially outward from the bead core (2) of the tire into the tire sidewall (3). Alternatively, he insert (8) may be positioned higher in the sidewall portion of the tire and away from the bead core (2). Such insert is a rubber composition containing a dispersion of an ultra high molecular weight polyethylene and a dispersion of a starch composite.
