2nd Gen 17x9 wheels/tires

[ES ARE 71]

Purchasing 17x9" wheels for my 2nd Gen WS6 equipped Firebird. What is the largest tire I can fit without any rubbing/interference issues??

A 275mm tread is about all that will fit in a stock wheel well. anything wider will start to stick out to even with the fenderline and beyond. A 275 will still be contained within the fender.
