The run-flat tire insert is for use with a wheel having flanges, and a corresponding pneumatic tire having sidewall tire beads with a bead lock edge. The run-flat tire insert includes a deformable annular insert member having a generally U-shaped cross-section with a band portion between opposing leg portions extending radially inward towards the wheel. The deformable annular insert member is made of a fiber-reinforced composite material. The deformable annular insert member is configured as a spring that deflects under load and transmits vertical load forces on the band portion to lateral forces at ends of the opposing leg portions adjacent the bead lock edges of the pneumatic tire against the wheel flanges.
