A vehicle traction system that is operably coupled to a vehicle and is deployable to assist in providing improved traction on surfaces such as but not limited to snow or ice. The present invention includes a housing that is annular in diameter and mounted intermediate inner and outer dual wheel flanges. Movably coupled with the housing are a plurality of connection members. The connection members have secured thereto tractions pads. The connection members are configured to extend outward to place the traction pads in position to engage a surface on which the vehicle is superposed. The connection members include an engagement plate distally mounted from the traction pads. The connection members are configured to extend outward to place the traction pads in position to engage a surface on which the vehicle is superposed. The connection members include an engagement plate distally mounted from the traction pads. An air bladder is adjacent the engagement plate and is operable to transition the connection member to its second position. A biasing member is operably coupled with the connection member and is configured to return the connection member to its first position.

A dual wheel assembly comprising a hub body that includes a central hub having a plurality of apertures to connect to bolts of a vehicle. The hub body includes a tire rim integrated with the central hub and having an outboard flange, an inboard flange and a drop center between the outboard flange and the inboard flange. The hub body includes a rail wheel integrated with at least one of the central hub and tire rim. The embodiments further include a triple wheel assembly and a vehicle with at least one of the dual wheel assembly and the triple wheel assembly.

The present disclosure relates to a wheel apparatus that includes a rim module coupleable to an axle and a solid tire module that extends from the rim module. The solid tire module includes a plurality of tread teeth that form a peripheral edge. The peripheral edge forms at least a portion of a tire profile. Each tread tooth of the plurality of tread teeth has a spatial specification that includes a circumferential width, a radial height, an edge shape, and a circumferential gap width. The spatial specifications of the plurality of tread teeth are non-uniform. In one embodiment, the solid tire module has a non-circular rotational trace. In another embodiment, at least a circumferential region of the peripheral edge comprises a sequence of tread teeth having sequentially increasing radial height.
