摘要： There is provided a pneumatic tire having an aspect ratio of not less than 60 and considerably improving run flat durability as compared with the conventional type of the run flat tire, wherein at least one cushion rubber layer having a loss tangent lower than a loss tangent ( tan δ ) of a coating rubber for cords of a carcass ply is arranged between an end portion of a belt and a reinforcing rubber layer in a shoulder region and between mutually adjacent tire constitutional members. And also, when the carcass is comprised of plural plies, at least one ply is separated off in a zone beneath the belt, whereby the ride comfort against vibrations can be more improved.

摘要： When feedback control is carried out to ensure that the drive torque of an electric motor(20) for driving each wheel of a vehicle should be equal to a motor torque instruction value, micro-vibration is applied to each tire by superposing a micro-vibration signal to a drive signal for the above electric motor(20) to change the slip ratio-friction characteristics themselves of the tire to control friction force between the tire and the surface of a road, thereby controlling the running performance of the vehicle.
