The present invention relates to a novel snow chain device for providing good traction to a vehicle tire on a snowy surface. The device is capable of being removably mounted on the tire with reduced physical effort and in multiple configurations. The device can be used in modular fashion and a range of patterns and configurations making it suitable for use on different tires as well as under varying driving conditions. Also it is possible to cover the entire surface of the tire as well as a partial surface. The device comprises of a plurality of link members and a plurality of base members. The base members can be affixed to the external tire surface and the link members can be removably secured to the base members.

A traction aid apparatus for a motor vehicle wheel. The apparatus has an elongated main body; a first securing member located at the first end or near the first end of the elongated main body and projecting downwardly comprising a surface for engaging a first side wall of the motor vehicle tire; a second securing member projecting from the elongated main body comprising a surface for engaging a second side wall of the motor vehicle tire opposite the first side wall of the motor vehicle tire, a tension mechanism connected to the elongated main body or the second securing member; and a flexible wheel engaging member that is configured to pass through an aperture in the motor vehicle wheel to the tension mechanism to secure the traction aid apparatus to the motor vehicle wheel.

A pneumatic tire includes a tread rubber region 5 a belt region 6 including a belt 61 and a contact patch pressure reducing rubber region 7, wherein tread rubber region 5 includes base rubber layer 51 and cap rubber layer 52. The two ends of the tread surface at shoulder lug 55 have first end 551 and a second end (not shown) which is located toward an interior in a tire width direction from first end 551. A contact patch pressure reducing rubber region 7 is disposed at a location between belt 61 and base nibber layer 51. The modulus of contact patch pressure reducing rubber region 7 is lower than the modulus of base rubber layer 51 and is lower than the modulus of cap rubber layer 52.

A tire traction assembly for mounting upon a tire. The assembly includes a plurality of cables with brackets at opposing ends which are each in a pivoting engagement with the cables. A toothed member is attached to a first of the two brackets and configured for engagement with a ratchet mechanism attached to the second of the brackets to releasably secure the tire traction assembly around the tire. A plurality of traction cables configured to traverse the rolling surface of the tire are located in-between the brackets. The brackets may include a planar tread plate which has opposing planar side surfaces configuring the brackets to a U-shape.

A tire traction device can include a primary strap configured to extend around at least a portion of a vehicle tire; a traction plate having a channel configured to receive the primary strap, and one or more traction-enhancing surfaces extending from the channel; and a base member having a first surface adapted to sit on a circumferential portion of the vehicle tire, and a second surface opposite to the first surface, wherein the second surface defines a recess adapted to receive the channel of the traction plate. Other features and embodiments, and a method of attaching a tire traction device to a vehicle tire, are also described.

A traction aid for a motor vehicle, comprising an elongated main body having a top and a bottom surfaces, the elongated main body having thereon a series of teeth and a sliding mechanism, a first securing member located at an end of the main body and projecting downwardly and a second securing member located at the bottom surface of the main body and attached to the sliding mechanism. The sliding mechanism allows movement of the second securing member towards or away from the first securing member along the bottom surface of the main body. The traction aid further comprises a securing mechanism configured to move the sliding mechanism and the second securing member towards the first securing member in order to squeeze a tire of the motor vehicle between the first and second securing members.

A disabled vehicle moving device configured to allow movement of a vehicle includes a sleeve made of a flexible material and configured to be mounted over a radially outer surface of a tire/wheel assembly of the vehicle that is locked for rotation. A cover is made of a flexible material and configured to be mounted over the sleeve and the tire/wheel assembly of the vehicle. A lubricant is arranged between the sleeve and the cover. The cover rotates relative to the sleeve and the tire/wheel assembly to allow the vehicle to be moved.

A tire traction device can include a strap configured to extend around at least a portion of a vehicle tire; and a traction plate. The traction plate can have a lower surface adapted to sit on a circumferential portion of the vehicle tire, an upper surface opposite to the lower surface, a channel configured to receive the strap, and one or more paddles extending upward from the upper surface. Other features, embodiments, and kits, and related methods are also described.
