Tire and wheel sizes
Here you will find some popular tire and wheel combos that people *are* running on their cars. This is meant to apply to the 83-88 SS's.
It is important to note the stock bolt pattern as well, it is "5 on 4 3/4".
stock = 215/65 on 15x7 front and rear
Front tire/wheel:

235/60 R15 on 15x7 is by far the most popular size for all four corners.
245/50 R16 on 16x8 is my personal favorite and what I run on my SS using 4 16x8 f-body front wheels.
