Abstract
A rigid, metal strap has a hook formed on one end and a handle on the other. The hook is disposed to be inserted between a tire rim and a surrounding, tubeless tire, only one sidewall of which (the inboard side) has been mounted on the rim. The inner, terminal end of the hook is engaged with and retains the bead on the inboard side of the tire against the circumferential flange formed on one side of the rim. An adjustable clamp on the strap is releasably clamped to the opposite side of the rim to secure the strap to the rim and therefore to hold the inboard tire bead against movement. A turnbuckle is pivotally mounted at one end on the strap adjacent its handle and has a hook on its opposite end engageable with the outboard bead of the tire, so that by adjusting the turnbuckle the outboard side of the tire can be spread away from the rim.
