Scrap tire from highway shoulder.
Scrap carpet from a dumpster.
Old plastic shopping bags.
and some shoe glue.
Angle grinder with cut off wheel.
Something to cut rubber and carpet, I used tin snips and medical scissors.
Step 1: Mark and Cut
Then use a cut-off wheel on a grinder to cut through the steel cords in the tire. (very smoky.)
Once through the cords, cut out the tread with some tin snips or something.
This is messy with black stuff everywhere; put down some cardboard or something. This also smells like the county fair demo derby.
Step 2: Drill Holes
Step 3: Cut Carpet to Fit
Make holes in the carpet to match the tread holes drilled earlier.
Glue the carpet to the tread with some shoe glue.
Step 4: Make Straps
-Take the ends of the braided bags and use the candle to melt the ends into hard tips. Leave 2 straps with an unhardened end.
-Route these straps into the holes as shown in the pictures; tie the forward strap to the back cross strap and trim off the extra plastic.
-Under the shoe, melt the plastic strap tips with the candle and smush 'em flat, this will harden and hold the straps on the shoe.
