In your post #361, Those look a lot like the 15x7 fifth ave wheels I have for both cudas, right down to the center web. Are you sure those aren't 15x7s ? Measurement is taken from bead flange to flange not edge to edge. I say this because if your using these as a guide and they are 7s, and you go ahead and order 8s thinking these are 8s, you may run into fitment problems.
