Hey Kustom,welcome to camaros.net. Check the wheel & tire forum, and do a search, the answers are there a thousand times... This time tho... 2 different 15x8's... vette wheels have more backspace (distance from inside edge of rim to mounting flange) 4.5" or so. Chevelle & Monte Carlo wheels have 4" bs. If that is what you have, you can fit a 255 or 265 / 60 / 15. If you have vette wheels... do the search, they stick out too far, and the tires will rub the fenders if they are too big.
Although this may not be apples-to-apples, I have 245/50-16 on the front with Global West springs which dropped it about 1 1/2" or so. The key was getting the car aligned with 1* negative camber to tuck the top in and removing the upper inner fender bolts ( will put button head ones in when I can ).
