That's a hard question to answer without knowing the height of the rear of the car. I have 245-45-17s on my 67 Dart with the offset shackles on a 7" wide wheel, and there is plenty of room for the tire between the wheel lip and the spring. A 275 would fit with the correct offset wheel.
Now, your tire is about 2.3 inches taller than my tire, which means it would go 1.15 inches further up in the wheelwell than mine. Contact could possibly occur up there, but I wouldn't know. Probably not with a set of super stock springs, but we have no idea where the rear of your car rides.
