The first and second supports may be positionable to prevent the tire from rotating relative to the first and second extensions toward the base. ## Claims ### Claim 1 A tire manipulator comprising: a base; first and second extensions coupled to the base and configured to support a tire, each of the first and second extensions including a first end coupled to the base and a second end configured to support the tire; and first and second supports movably coupled to the first and second extensions, respectively, the first and second supports being disposed between the first and second end of each of the first and second extensions; wherein the first and second supports are positionable to prevent the tire from rotating relative to the first and second extensions toward the base. ### Claim 2 (depends on 1) The tire manipulator of claim 1, wherein the base is configured to be coupled to a vehicle. ### Claim 3 (depends on 1) The tire manipulator of claim 1, wherein each of the first and second extensions includes a first portion movably coupled to the base and a second portion movably coupled to the first portion. ### Claim 4 (depends on 1) The tire manipulator of claim 1, further comprising: first and second clamping members coupled to the second end of each of the first and second extensions, respectively, each of the first and second clamping members including a clamping surface configured to engage a surface of the tire. ### Claim 5 (depends on 4) The tire manipulator of claim 4, wherein the clamping surface of each of the first and second clamping members is configured to engage a treaded surface of the tire, and wherein the first and second supports are configured to engage a sidewall of the tire. ### Claim 6 (depends on 1) The tire manipulator of claim 1, wherein each of the first and second supports includes a mounting shaft that extends into a corresponding aperture provided in each of the first and second extensions. ### Claim 7 (depends on 6) The tire manipulator of claim 6, wherein each of the first and second supports is rotatable to a first position wherein the first and second supports prevent the tire from rotating toward the base, and to a second position wherein the tire is permitted to rotate toward the base. ### Claim 8 (depends on 1) The tire manipulator of claim 1, wherein each of the first and second supports is selectively lockable in each of the first and second positions. ### Claim 9 A tire manipulator comprising: a base; and first and second extensions coupled to the base and configured to support a tire, the tire having a treaded portion and a sidewall extending from the treaded portion, each of the first and second extensions including: an arm member coupled to the base; a hand member coupled to the arm member; a clamping member extending from the hand member and configured to engage the treaded portion of the tire; and a fall-back support coupled to the hand member and configurable to extend from the hand member to engage the sidewall and prevent rotation of the tire toward the base. ### Claim 10 (depends on 9) The tire manipulator of claim 9, wherein the base is configured to be coupled to at least one of a vehicle and an articulated crane. ### Claim 11 (depends on 9) The tire manipulator of claim 9, wherein the fall-back support is movably coupled to the hand member and is moveable between a first position and a second position, wherein the fall-back support prevents rotation of the tire toward the base when in the first position, and wherein the fall-back support permits rotation of the tire toward the base when in the second position. ### Claim 12 (depends on 11) The tire manipulator of claim 11, wherein the fall back support includes a first collar member configured to engage a second collar member provided on the hand member, and wherein the first and second collar members limit the fall back support to a range of motion defined by the first and second positions. ### Claim 13 (depends on 11) The tire manipulator of claim 11, wherein the fall-back support includes a generally cylindrical member configured to engage a correspondingly shaped aperture defined in the hand member to rotatably couple the fall-back support to the hand member. ### Claim 14 (depends on 11) The tire manipulator of claim 11, wherein the fall-back support extends in a parallel direction to the sidewall of the tire when in the first position. ### Claim 15 A maintenance vehicle comprising: a vehicle body; and a tire manipulator coupled to the vehicle body and configured to manipulate a tire, the tire manipulator including: a base portion; a pair of extensions extending from the base portion, each extension including a gripping surface configured to engage a surface of the tire; and a pair of fall-back supports disposed between the base portion and the tire and positionable to prevent the tire from rotating toward the base portion in the event of slippage between the gripping surfaces and the surface of the tire. ### Claim 16 (depends on 15) The maintenance vehicle of claim 15, wherein the base portion is moveable relative to the vehicle body. ### Claim 17 (depends on 15) The maintenance vehicle of claim 15, wherein each extension includes a first portion coupled to the base portion and a second portion coupled to the first portion and including the gripping surface. ### Claim 18 (depends on 15) The maintenance vehicle of claim 15, wherein each of the extensions includes a top surface and a bottom surface, and the fall-back supports extend from the top surface of each extension. ### Claim 19 (depends on 15) The maintenance vehicle of claim 15, wherein each of the fall-back supports engages a corresponding aperture in each of the extensions to rotatably couple each of the fall-back supports to one of the extensions. ### Claim 20 (depends on 15) The maintenance vehicle of claim 15, wherein each of the fall-back supports is selectively lockable in a plurality of positions.
