First - you car would have most likely been 7.35 X 14" or
D70 X 14" - unless it was an export and had some odd required tire equipment...
Next - read through thise 'sticky' in the Wheels/Tires forum - https://www.camaros.net/forums/showthread.php?t=153144
It will give you a good idea of what guys are running for tire sizes and types
Other than what will clear - the tire/wheel set-up on a car is mainly a personal preference type of thing. You just have to see what looks best with you particular suspension set-up and gives you the look and stance you like.
Tire manufacture is really not as important to me anymore - they are all designed pretty closely for street use designs.
Some brands are even a different name on a slightly different mould than another brand with a completely different price and availablity structure - but still owned by the same parent company...
Just check the compound (wear), heat and speed ratings to be sure they fit you needs.

It can be hard to respond to some posts because the info is really already on this site - you just have to 'mine' (use the search
) for it - and there are a hundred other posts you want to read...
Hope this helps;
