Garages that perform tire changes routinely have to get rid of junk tires. These tires are damaged and cannot be repurposed. Also, they are potentially toxic to the environment if processed with regular trash. There is a way to pack both junk and new tires onto a tractor trailer for transport, and it's called "lacing." Tires are packed and stacked in rows slanting in different directions. This maximizes space while ensuring stability.
Put on a pair of work gloves for safety purposes. Not only can tires be grimy, but damaged tires pose other risks, like exposed metal.
Choose a direction, left or right, that you will stack the first row of tires.
Lean the first tire against the wall at angle. Perform a "bump test" on the first tire. Kick the tire. If it stays in position, it is well placed. If it falls down, the reposition the tire and kick it again. This is important for the stability of the interlaced stack while transporting. Falling tires can be hazardous.
Lay a tire or two flat on the ground, and then lay another tire against them at an angle. This is a way to start an interlaced tire stack if there is no wall nearby.
Lay other tires against the first one, at the same angle, and fill out the row
Start a new row on top of the first one. This time, slant the tires in the opposite direction.
Keep alternating the slant direction for each new row that is added. Once you reach the ceiling of the trailer, start a new stack following the previous steps until all tires are packed into the trailer.
