Is a 295/50 R15 possible?

here is a shot of my factory 74 360 duster sporting 295-50-15 tires on 15x8.5 in slots.these are not my normal wheels for this car.it sports factory ralleys.but i thought i would use this car as i can't get a good picture of them on my other car.as you will tell by the other orange duster in my shop among all my other junk.
