摘要： A wheel-and-tire apparatus has a pneumatic tire with two or more circumferential tread sections, the relative diameters of which may be adjusted to select the tread sections in contact with the road. The tire may have one or more air chambers. The apparatus facilitates selective use of tire tread designs and compositions having different performance characteristics to suit particular road conditions and vehicle operating parameters. Adjustment of tread section diameters is accomplished using tread diameter adjustment means having a source of compressed air. Sensors monitor selected operational parameters of the vehicle and transmit corresponding signals to a computer, which selects an optimal configuration of tread section diameters to suit the data from the sensors. The computer sends a corresponding signal instructing the tread diameter adjustment means to adjust the diameter of one or more tread sections as required to achieve the selected configuration of tread section diameters.

摘要： A wheel-and-tire apparatus having at least two coaxially mounted tires is disclosed in which the diameters of one or more of the tires in the apparatus may be adjusted to select the tire or tires which are to be in contact with the road surface. The apparatus facilitates the selective use of tires having different performance characteristics, as may be desired or preferred to suit particular road conditions or vehicle operating conditions. The diameters of particular tires are increased or decreased as required to achieve a desired configuration of relative tire diameters, using tire diameter adjustment means such as one or more pneumatic pumps mounted in association with the apparatus. Sensors monitor selected operational parameters of the vehicle and transmit corresponding signals to a computer which selects an optimal tire configuration to suit the particular combination of operational parameters received from the sensors. The computer then transmits a corresponding signal instructing the tire diameter adjustment means to adjust the diameter of one or more tires in the apparatus as required to achieve the selected optimal tire configuration.
