Abstract: A chipper (40, 43, 54) for use in a pneumatic radial ply runflat tire (49) comprises cord reinforcements (42, 42′) making an angle, &agr;′ of between 30° and 50° relative to the circumferential direction. The radially outermost edge (46, 50) of the chipper is located between 10 and 15 millimeters above the wheel rim flange (56) of the wheel-mounted tire and between 5% and 20% of the section height SH of the tire. The chipper is disposed axially inward of the ply turnup end (58). The chipper (40) may comprise a single layer of cords (42), or the chipper (43) may comprise two layers (47, 47′) with the -cords (42, 42′) in the two layers being crossed to form mirror images across a radial reflection axis.
