I've also seen Delta/Jet 14" bandsaw tires. They are just plain
strips of flat rubber. I very much doubt those wheels have a
recess. I bet they're glued on too.

These 14" bandsaw wheels do have a recess, and a crown is machined into
the surface of the wheels. There are two types of tires, rubber and
polyurethane. The rubber tires are glued in place, but the polyurethane
ones are heated, usually in water, and stretched into place with no glue.
