Things You'll Need
- Large tire from 150-ton truck
- Reciprocating saw
- Concrete mix to pour 0.5 yards
Instructions
Cut the bead off one side of the tire with the reciprocating saw. The bead is the inner part of the sidewall of the tire.
Lay the tire on the ground where the water tank will be. Place the side with the bead on the ground.
Pour the concrete into the bottom of the tire to fill up the bead. The concrete will form the bottom of the tank as it adheres to the tire.
Fill the tank with water.
