This disclosure relates to a system and method for changing tires. A tire-changing device can comprise a frame and a tire holder. The frame can comprise a U-shaped frame and an L-shaped frame. The U-shaped frame can comprise a base and a pair of shafts. Each of the shafts can be connected at both ends of the base. The L-shaped frame can comprise a short beam and a long beam. One end of the short beam can be attached at the bottom of the long beam. The other end of the short beam can be connected at the middle portion of the base. The tire holder can be attachable with the L-shaped frame. The tire holder can comprise a base plate, a plurality of prongs, and an L-shaped connector. The base plate can comprise a disc and a plurality of blades. The disc can be placed at the center of the blades. Each of the prongs can be attached at the top edge portion of each of the blades. The L-shaped connector can comprise a vertical member and a horizontal member.

A cart is disclosed having a rigid base with a plurality of cutouts, bottom and top sides, and at least one peripheral edge. The bottom side has at least one removable, lockable caster at each bottom side corner. The cart has a rigid cradle with bottom, back, and top sides, and at least one peripheral edge. The opposing sides of the top side have horizontal rollers mounted on flanges. The cradle has a handle, tool hooks, a lug nut tray, and a wheel retainer. An actuating lift coupled between and centered on the base top and cradle bottom is movable between a lowered position and a raised position. The base has an elevated portion and is switchable between raised and lowered configurations, setting the cradle's maximum height, by removing the casters and decoupling the lift from the base; flipping over the base; reattaching the casters; and recoupling the lift.

A wheeled cabinet includes a container including compartments, a rear handle, drawers, and a storage between the drawers and a base; a pneumatic assembly including an inlet, connectors, a pneumatic cylinder on the base, a piston rod configured to move alternately upward and downward relative to the cylinder, and a controller for activating the cylinder; a lifting assembly including two opposite rails upwardly disposed on two sides of the base respectively, and an inverted U-shaped frame member slidably disposed on the rails and having an underside of a top secured to the piston rod; and a tire support assembly including a support secured to the frame member, two slides on two sides of the support respectively, a sliding tray secured to the slides, a slot on an inner surface of the tray, a moveable tab in the slot, and two rollers on two sides of the tray respectively.

A wheel ramp is provided for use with a motorcycle stand. The wheel ramp includes a pair of side plates, each of which has a first side end and a second side end distal thereto. At least one of the side plates has a curved end about the first side end to secure onto a portion of the motorcycle stand. The wheel ramp includes a top plate secured between the pair of side plates and an adjustable height mechanism configured to adjust the height of the second end of the side plates and thus adjust the height of the top plate about the second end. The top plate when moved under the wheel of the motorcycle is movable to engage and lift the wheel of the motorcycle into and out of engagement with the motorcycle.

According to an aspect of the present disclosure, a locking turnplate includes a cylinder body having a cylinder chamber. A piston is received in the cylinder chamber and a mid-plate is disposed above the cylinder chamber of the cylinder body. A top plate is supported above the mid-plate by a bearing assembly including a plurality of spaced ball bearings. A bushing is fixedly attached to the top plate and extends through an aperture in the mid-plate. The bushing includes a flange that engages a bottom shoulder of an aperture of the cylinder body, wherein applying a pressure to the cylinder chamber presses the piston toward the mid plate and causes the cylinder body to pull downward on the bushing and the top plate in order to compress the ball bearings and prevent the top plate from moving relative to the mid plate.

In a system and method for replacing a vehicle wheel an electric motor with a drive shaft is concentrically connected to a first gear. The first gear may connect to a symmetrical bolt locking gear array having several bolt locking gears arranged such that each bolt locking gear rotates in the same direction that the first gear rotates. Each bolt locking gear may have a cylindrical hole at its center. The cylindrical hole may be outlined with an inner spiral thread, which connects to a set of power bolts that are outlined in an outer spiral thread which interlocks with the inner spiral thread. A power jack system having a plurality of extendable and collapsible bases is provided in the undercarriage of the vehicle to raise and lower the vehicle. An app running on a mobile device may control the raising/lowering of the vehicle and tightening/loosening of the power bolts.

A corrosion-resistant wheel centering sleeve is provided to aid in centering a wheel about a wheel hub. The wheel centering sleeves have an adjustable thickness in order to coordinate with various-sized gap spaces in the wheel hole between the wheel and the stud.

A method for removing a dual wheel from a primary wheel of a dual wheel assembly. The dual wheel is secured to the primary wheel while forming a gap between a periphery of the dual wheel and a periphery of the primary wheel. The dual wheel and the primary wheel each may have a tire mounted thereon, with the dual wheel assembly being carried on an axle. The method comprising inserting an uninflated, high pressure airbag at least partially into the gap between the dual wheel and said primary wheel; inflating the high pressure airbag to expand the gap between the dual wheel and the primary wheel so as to separate the dual wheel and the primary wheel; and finally, removing the dual wheel from the primary wheel. Likewise, a similar method can be used to remove a wheel from an axel, the wheel being carried on and secured to the axel while forming a gap between a periphery of the wheel and a periphery of the axel.

The disclosure is directed at a wheel mounting guide bar that is used to assist in the replacement of wheels on a vehicle. The guide bar includes a shaft portion; a sleeve portion, the sleeve portion sized to fit a stud on a wheel hub; and a connector connecting the shaft portion to the sleeve portion, the connector enabling the sleeve portion to move with respect to the shaft portion.

A tool set for fitting a wheel to a wheel hub of a vehicle. The tool set comprises a wheel carrying bar and a support peg. The wheel carrying bar is configured to pivotably engage with the support peg.
