Please help with tire/wheel size

[Rustynut]

I have a 68 SS with 14" rallys. I want a new set of wheels and I think Cragars are probably.my favorite choice. I want to go 15", but I need some recommendations on width/profile. If you can show a pic, that would be great!!

I have 15" Cragars on my '68 SS coupe.   Running 215/65's with no problem.  Standard Cragar offsets...rear rims are 8", fronts are 7 somethings.
