94-95 Cobras cane factory stock with 255/45/17s on the 17x8 wheels. Only sn95 with 17x8s to run that setup. All other 17x8 cars ran 245/45/17

I run 17x8s with 255/45/17 out bsck and it looks fine. Perfect amount of "meat" for the rim size

It's an odd tire size and not that many manufactures make it. Mine are BFG Sport comp 2s

The aspect ratios on those tires are sufficiently different that they may look a little weird on the same car.
The 255/50 will have a 5" sidewall while the 245/45 sidewall will be 4.3". It may not sound like much, but this results in tires that are 27.1" and 25.6" tall, respectively.
255/50-17s are primarily a truck tire. A better bet for the rear would be some 275/40s like Nick recommended or a 255/45 as was factory equipment on '94-'95 Cobras (which also came with 8" wide wheels. 265/40 may also be a good option as the aspect ratio puts them on par with a 245/45 with a total diameter of 25.4".

My recommendation would be to go with the 275/40s.
