71 Dart -- Will they fit?

245s on my wheels would be a tight fit. My '72 has a 7 1/4 in it. Leaves about 3/4-1" on the spring side 1/2ish on the fender side. 245s on a 6" rim might make them a little narrower in the section and a wee bit taller. In theory you should have less wheel on the fender side than I do by an inch. That could only help matters. I never tried the fatter tires on the front, might be a fun experiment the next time I'm messin with it.
