A tire for vehicles offering low rolling resistance wherein the ground-contact surface area is variable as a portion of the tread part can be retracted and / or extended using pneumatic, mechanical or hydraulic force to withdraw from, or come into contact with the road surface before, during or after operation permitting more efficient operation wherein the material used within the tread part that retains contact with the road may generally have a smaller internal friction loss than the material used in conventional tires and the rolling resistance is thereby reduced when the retractable portion of the tread is selectively withdrawn from contact with the road surface furthermore achieving a smaller ground-contact patch footprint. The achieved object of a tire with a lower rolling resistance yields improved fuel consumption efficiency. Improvements in exterior and interior noise levels and a reduced tendency to exhibit hydroplaning action are also attained with a variable groove volume to tread surface-contact ratio. Within one embodiment of the present invention, an automated microcomputer-based tire control system is disclosed useable to command the motion of the moveable tread portion of the said tire in response to various operational scenarios.

A pneumatic tire is provided in which hydroplaning performance, transverse slipping performance on snow, straight forward traveling stability, and the like are maintained by a pair of circumferential grooves. A large number of second blocks and center blocks are formed, by a large number of transverse grooves, in a center tread region positioned between the pair of circumferential grooves. A reinforcing portion is provided at the center block. This reinforcing portion faces, in a circumferential direction, the second block with a narrow transverse groove therebetween. Another reinforcing portion is provided at an end portion of the second block. This reinforcing portion faces, in the circumferential direction, the center block with a narrow transverse groove therebetween. Each block is reinforced by the reinforcing portion provided integrally therewith. When a block receives load in a direction of deformation, the block abuts and is supported by the reinforcing portion of a block adjacent thereto. Thus, even if a number of transverse grooves is increased, deformation is suppressed. Accordingly, good off-road performance, on-snow performance, and on-road traveling performance can be obtained.
