A puncture resistant air-filled tyre comprises separate outer 2 and inner 3 thin bands made from strong flexible material such as metal or carbon fibre situated around the inside of the tyre, close to the tyre contact areas and protected by a seal 8. Small air holes or linear slots 1 draw air into the cavity if a plate is displaced by a puncture, and bellows 5 allow the bands to adjust within the tyre. The bands significantly reduce the probability of sharp objects such as nails and screw nails that will ordinarily penetrate the air cavity of normal air tyres causing punctures.
