stock wheel size
Some cars, especially V6 cars, came with 235/55/16 tires. My Z28 is one of the rare ones that came with that size Eagle GA tires. Since they are not Z rated, my car came with a 117 mph speed limiter and a steel driveshaft.
But yes...all factory wheels are interchangeable.
Only Firehawks, SS's, and WS6's came with 17 x 9" wheels. All other cars came with 16 x 8" wheels, except for the very poorly optioned cars that came with 15" steel wheels with hubcaps.
