275/60x15 on a 15x8 with 4.5 or 4.25 BS (depending on how you measure that) is pretty much the default size.
I've done that on a couple Dusters.
There's some variance in panel fitment, though, from car to car and even side to side, one side usually has more room than the other.
Generally it's tightest at the front bottom corner of the quarter, I had to use a 1/4" spacer on one car between the ft spring hanger and where it mounts to the car.
If the car sits lower than stock, check the inside of the tubs where they narrow.
