fox stang tire question

What is the biggest tire you can run on the rear for the big and skinnie look when running a stock rearend(1990 8.[img]/phpBB/images/smiles/icon_cool.gif[/img] and no mods to the fender? Right now I have centerline covo pros that are 8.5 wide with 4 7/8's back spacing. Tires are 265/50/15.
With this setup I need some air in the airbags to keep the fender off the tire...especially with people riding in the back during normal street driving.I would love to run a 295/50. Any wheel width and backspacing combo out that you guys know of to get that done? Im thinking I just fo with 275/50/15 drag radials otherwise since the car is really not driven that much.

Here's a couple of pics with the above mentioned wheel/tire combo. I WANT MORE TIRE!! [img]/phpBB/images/smiles/icon_biggrin.gif[/img]
