A motorcycle wheel changing tool is presented that utilizes a rolling carriage that immobilizes the front or back wheel utilizing flat steel swing arms and a tension spring that holds the wheel in place with a knockout retaining rod through the wheel. The entire unit can be rolled and/or lifted in place to work in conjunction with a motorcycle stand. There is a folding handle that expands or contracts to accommodate different size tire/wheel widths and can pull the unit. The rolling wheels can be raised or lowered for different motorcycles depending on the height of the bike in relation to the wheel stand. Additionally, four large eye hooks can be raised or lowered to secure the wheel. Two threaded rods are utilized that secure both angle ends in place to secure the unit so that it is perpendicular to the wheel and keeps the unit from flexing.

A recessed portion is formed in each tire side portion of an agricultural machinery pneumatic tire. Rigidity at the part of each tire side portion where the recessed portion is formed is reduced. This enables each tire radial direction outside portion to be made to tilt over toward tire width direction outside with the recessed portion as a point of origin without reducing the internal pressure, enabling the ground contact width of a tread portion to be enlarged. Since there is no need to intentionally reduce the internal pressure in order to reduce the ground contact pressure, bead portions do not tilt over more than necessary, and there is no reduction in the durability of the bead portions. 1.
