Tire with extended mobility, useful for enabling the vehicle to continue on line in the event of a sudden pressure loss, comprises several impermeable layers

摘要

The adapted tire comprises a skeletal-type reinforcing structure anchored on each side in a cushion attached to a rim of the wheel. Each of the cushions extends radially externally in the form of sides, the latter reuniting radially a rolling band. The reinforcing structure extends circumferentially from the cushion to the side to an armature. Each of the cushions also comprises an anchorage zone enabling maintenance of the reinforcing structure, and each of the sides is reinforced by an insert consisting of a rubber composition capable of supporting a load (corresponding to the weight of the vehicle) during a situation of sudden reduction of inflating pressure. The tire also comprises an internal layer consisting of rubber composition impermeable to the inflating gas and covering the whole of the interior of the tire. A bonding layer comprising a rubber composition is also disposed between the side inserts and the internal layer.
