Materials:

Used Tire
100 feet of natural fiber rope. ( Exact measurement depends on tire size. Thicker rope will make the process much faster. We used rope that was 5/8th inches thick.)
Carriage Bolts, Nuts, and Washers. ( Diameter and length of bolt needs to be the same as the drill bit.)
Two wood panels with equal circumference as tire. ( Obtain from hardware store)
Padding
Fabric
Staple Gun
Staples
Hot Glue Gun
2-3 packs of hot glue gun sticks
Hammer
Drill
Drill Bit
Sealant

Step 1:

Begin with a clean tire. Place wood panel onto the tire.

Step 2:

Mark the wood in six spots, spaced evenly along the very edge of the wood panel. Distance between the spots will depend on the size of the tire.

Step 3:

Using a power drill, drill through the six spots you marked. Go through the wood and the tire.

Step 4:

Put the bolt in the hole though both the wood and the tire. It may be necessary to hammer the bolt in.

Step 5:

Attach washer and nut to the bolt, use a ratchet to tighten.

Step 6:

Trace the second wood panel onto the padding and cut the padding to the appropriate size.

Step 7:

Place the padding on top of the second wood panel.

Step 8:

Wrap padding and wood tightly with fabric, then staple. Excess fabric may be cut off, or stapled to the back.

Step 9:

Finished Cushion.

Heat Hot Glue Gun

Step 10:

Mark the circumference of the cushion with a light colored sharpie, or chalk, on top of the tire so you know where to begin wrapping the rope.

Step 11:

Apply glue directly to the tire and position the rope onto the glue. Continue until the entire tire is covered in rope. Use multiple people for this step, if possible.
