PNEUMATIC TIRE HAVING DUAL AIR RETENTION QUASI ENVELOPES

摘要

A pneumatic rubber tire (1) is provided having inner and outer air retention quasi envelopes which individually substantially envelop the tire air chamber (2) and which are comprised of a first inner quasi envelope as an integral innerliner (7) and a second outer quasi envelope as a combination of sidewalls (6) and tread (5). Such pneumatic tire is of a relatively conventional open toroidal shape. The innerliner (7) and the sidewall-tread combination are termed as being quasi envelopes in a sense that a rigid rim (11), onto which the tire is to be mounted and inflated, is used to complete the closure of the tire's air chamber envelope. <IMAGE>
