The ones pictured, were on 03-06 Edge/Sport, XLT 4x4, including Fx4OR. 16"x7". Machined Aluminum.
Now....actual Tremor wheels are just like the ones in the picture, but are painted/or shaded to a darker color....pretty sure it's described as Dark Shadow Grey.
Don't know the proper Ford name for them though...gotta find my old brochures to find that out though.
