Is this one of the 4x6 horizontal/vertical bandsaws? Those can
get away with that because they are designed for only a single width of
blade -- 1/2". Anything much wider is likely to slip off (as well as to
attack the cover), and anything narrower will have its teeth (at least
the set) damaged by the contact with the metal wheels.

The crown is needed on saws which can handle a wider range of
sawblade widths -- and with a rubber tire they don't damage the set of
the teeth.

My wood band saw has crowns on
both wheels...

As do serious metal-cutting bandsaws.

Enjoy,
