A tyre assembly (fig 1, 10) comprises a wheel rim 12, a tyre 14 fitted to the wheel rim 12, and an annular insert 40 located inside the tyre 14 around the rim 12. In a rest state, the annular insert is diametrically larger than the rim. The annular insert is formed from a compressible material that causes it to contract diametrically in response to inflation of said tyre such that it shrinks it to the rim. The annular insert 40 is easy to fit and protects against pinch punctures, rim damage and de-seating of the tyre beads. Further feature may include a valve (fig 12, 32), with a valve head (52), having a fluid channel (60), and having an opening at the face of the valve in a radial direction.
