Abstract: A tool is provided for assistance in removing and installing tires on wheel rims. The tool can be provided with a handle having a tool head disposed at each end. Each tool head is designed to fit between a tire bead and an associated wheel rim so that when the handle is levered, a force is applied to the bead and rim that moves the bead over the rim. Each tool head has a substantially flat portion which can be easily fit between opposing tire and wheel rim surfaces. One tool head has a slightly hooked distal tip to enable axial engagement with a flange of the wheel rim, and thus can be used either for installing a tire on a rim or for removing a tire from the rim. Another tool head has a protrusion disposed near the tool midpoint to engage a flange of the wheel rim. The protrusion can be a roller member having a pin axis perpendicular to an axis of the tool handle. This roller can be fabricated from a soft polymer or rubber material so that the tool will not damage soft-metal wheel rims such as aluminum. The handle can have a pronounced curvature that allows a portion of the handle body to be received within the cavity formed by the wheel rim. This curvature allows for a greater range of motion of the handle, thus providing the user improved leverage as compared to prior tools. The tool heads may be permanently attached to the handle, or they may be removable to allow the user to customize the tool to the desired application.

Abstract: A tool is provided for assistance in removing tires from wheel rims. The tool has a rim engaging member with a lateral opening for engaging the flange of a wheel rim, and a tire engaging member movably coupled to the rim engaging member. The rim engaging member has a slot, within which a pin of the tire engaging member can slide to thereby allow the tire engaging member to rotate and translate relative to the rim engaging member. A roller is mounted on one end of the tire engaging member to exert a downward pressure on the tire sidewall, and a handle protrudes on an opposite end. A resilient roller is mounted on a lip portion of the rim engaging member to facilitate engagement between the member and the rim, and to prevent damage to the rim. The rim engaging member also may have a resilient roller for engaging a portion of the tire engaging member to enable smooth movement of the two pieces with respect to each other. The tool also has an adjustable tire bead hook member for supporting an upper tire bead while the tool is being used to remove the lower tire bead. This adjustable hook member can be adjusted to fit a variety of tire widths, including double-width tires.
