275/40/17 on a 17x8? is it okay?

Mopardude318, did you ever get a set mounted?

I tried some Fierce 275/40R17 tires on a set of '97 17x8 Mustang wheels, guy couldn't get the sidewall to pull down so he could mount them. Could be that the Fierce tires (Goodyear lower brand) are wider than most 275 tires, or the sidewalls are too stiff. Now I have a set of used tires I can't use without finding a different set of sheels, or a set of wheels that still needs a pair of tires.

For what it's worth, most of the Mustang guys I found that run that setup run a drag radial that is a little on the narrow side of the 275 section width spectrum.

And here is the thread where 72BBSwinger put his wheels and tires together in. FYI.
