Thanks all. I've decided to make life easier on myself and will be going with a tire the local tire shop can provide. Choices are getting slimmer every time I need tires it seems.
Here is a test fit with 255/60r15 in the rear and 235/60r15 up front. My main concern is that I want to keep a 2.5" rear exiting exhaust as I'm not willing to compromise on that with my street car.
