73 dart wide wheels/ backspacing questions

I am running 245/60/15 tires up front on police rims. Honestly I would not recommend it if you don't have adjustable strut rods or maybe polyurethane strut rod bushings. My car has year or two old rubber bushings up front and adjustable strut rods with heim joints. I think thats what keeps them from hitting. They are pretty close but don't hit. I would go smaller than 245 up front on a stock suspension. I feel like 225/60/15 would be a nice safe zone but Ill admit I haven't seen one of those tires in person lately so I cant say for sure.
