What (tire) manufacturers used this approach? Only selected makes or all?

All make do that I'v been told. So that when they were set in the racks it was easy to see and tell the tire size.

Aftermarket or OEM? Car Plants don't "rack" tires.

Tires are lots of fun in an assembly plant - they arrived packed by the thousands, herringbone-style, in rail cars, and the first five or ten were nearly impossible to remove from the load (kinda like removing the spring cage from a Posi unit ). In the winter, they were also frozen solid (and crushed flat). They were pulled from the rail car and loaded directly on a conveyor hook, in assembly line car build sequence, which took them through a 100'-long infra-red oven which thawed them and allowed them to regain some semblance of their correct shape. That conveyor took them into the "wheel room", where they were automatically tipped off the hook and dropped onto the tire/wheel mounting conveyor pallet that led into the mounters, inflators, and balancers.

This was all highly labor-intensive and non-value-added work, so virtually all assembly plants these days have an outside supplier mount and balance wheels and tires and deliver them in car sets, in sequence matching the assembly line; they come out of the truck in sets and go right on the cars as they pass by, with as little handling as possible.
