Tire sizes

Without going past the upper wheel well lip, how wide can I go for tires on the back? (eg: 255/50/15) I have stock rims on an 86 trans am. Any help is appreciated.

stock rims? check mfr specs on min rim widths, 15x7's right? the eagle gt II 275 60 15 min width is 7.5" so you wouldnt want to go any bigger than that
