- and
- a partial air-flow restrictor located in the cavity of the tire, wherein a chamber of air is formed between the inflatable air-flow restrictor and the partial air-flow restrictor and wherein the partial air-flow restrictor comprises an air passage to permit air flow through the partial air-flow restrictor into the chamber of air.
