sbp steelies,tires and dog dishes (set of 4)

How did you have them measured? Outside edge to outside edge is the incorrect way. You need to measure from inside bead to inside bead, this is done with the tire off.

With the tire off, you should be able to read the width stamping, so measuring wouldn't be needed anyway.

14" x 7" would be a very uncommon or custom made size for a 14" sbp wheel. Most are 4.5" or 5.5" wide.

But yours do look to be on the wider side.
