A pneumatic tire provided with beads each shaped to have heel and toe portions; each toe is provided with a radially inwardly annulus of elastomeric material which restrains the bead against axially inward movement even when the tire is deflated and also improves the fluid seal between bead and wheel rim. The tire may be fitted to a wheel having an annular notch for receiving the annulus on the bead toe.
