I would say you should treat that as a double-row rack because it looks like "single-row racks placed back to back" and because it looks like there is a longitudinal flue space and the definition for single-row racks states "racks that have no longitudinal flue space...".
If it's tire storage though, does it matter? That looks like rubber tire storage, on-tread, in a fixed rack without solid shelves.
