New wheels aren't high on the list of priorities but they're fun motivator to get the real work done.

The 15 x 8 steel wheels on the car now have a 4.3" back space with 225/60-15 T/A tires.

I want to have the exact same tire & wheel size on all 4 corners. So I used this cool wheel offset calculator to easily show the difference that a change in tire & wheel would make from the current setup.

Offset : 24mm
Backspace: 6.4"

Even with a Dr.Diff offset spring hangers, the rears may need a small spacer. I'm currently measuring ~2.0" from the leaf spring to the steel wheels but these 10" rims need an additional ~2.0".

For tires, these Kuhmo V720 look to have a good balance between performance and cost.

When GrassRoots tested them compared to the BFG Rival S,( which is nearly 2x the price), they held their own.

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.

If they are indeed 8s, where did he get them widened at because the late model style rims that came w the 4 hubcap nubs. And 5 extra holes in the webs for wire wheel cover lock bases like that didnt come anything wider than 15x7. I have seen them as 15x5.5 , 15x6 , and 15x7. I want the keep the fronts 15x7, but widen the rears to 15x8.
