Free tire 12.4x38

Mark a circle with a scribe just below the tread bars on one side.

Mark 3 seats that are 14" wide at 120 degree intervals.

Use a saws all to cut the rubber, and a grinder to cut the bead wires. leaving the seats attached.

Use 2X4 pieces about 35" (needs to be measured) that will bolt under the seat, and onto the top of the tread with two 1/4X20 carrage (round head) bolts on each tread end, and 3 of the same across the front of the seat to keep it down, not flapping.

Flip over and cut 4" of the bead off of the entire circle of the other side. (this helps it lay flatter and have a more usable bottom.

When placing it it is best to put two layers of bedding cloth under the "box" to allow water to get through, and keep weeds out. It also cleans up better when being moved.

I sold mine for 30$ after using it for 4 years with my son.
