Is a 295/50 R15 possible?

The strange thing is, I have 15x8 Draglites with 265/50's. All I did was trim the wheel well lips down and my tires fit. If I had another 1/4" backspacing, I could have gotten 275's in there (I still may). I have always heard that Dusters had much more room than Darts, I have seen plenty of Darts with 275's. Its become obvious the you need to measure and see what fits, it seems that everyone has different results.
