FIELD: automotive industry. ^ SUBSTANCE: in proposed beads of safety tyre instead of wire side ring, or in addition to wire side ring, tubular ring are used forming ring spaces in beads in which pressure is built exceeding tyre pressure. As a result, in case of damage and complete deflation of motion, said tyre will lie by inner surface of tread on side tubes keeping their pressure and thus partially preserve radius of rolling and pliability of tyre. Even at zero pressure, tyre is reliability help on disk rim owing to upsetting of bead heels in ring grooves of rim by pressure in tubes preventing turning off or slipping off of from rim, even at considerable side deformations. ^ EFFECT: improved safety on road. ^ 1 dwg |
