two images of tyre stacking arrangements.
The second image shows a pile of tyres in a 'laced' arrangement. This involves stacking rows of tyres so that one end of the tyre is placed on the end of the previous tyre, creating a sawtooth shape. Each row's 'sawtooth' runs in the opposite direction to the previous row, so that the rows are interlaced. The pile is stacked within a container.

A laced stack of tires is the conventional shipping method to load the maximum amount of tires into a box truck or container. A truck load of laced tires is also more stable than if the tires were carried in stacks. Lacing works best with tires of the same or similar sizes. With practice, the person stacking the tires can adjust the lacing pattern to best suit the tire and container sizes.
