A two-chamber safety tire for automotive vehicles capable of supporting the weight of the vehicle when either partially or completely deflated, thus allowing continued operation of up to about 50-100 miles. The outer chamber is constituted of an ordinary tubeless tire, while the inner chamber has no fabric reinforcement and is made of a thermoplastic elastomer having defined strain-stress properties. Particularly suited thermoplastic elastomers include polyetheresters and polyurethanes. The thickness of the inner chamber in sidewall and tread areas of the casing must be such that defined maximum strain and creep requirements at a stated pressure are observed. |
