Wheel measurement question

Ok thanks for the input i found some 15x7s on fb i guess i will just break down and buy them I just hate paying the shipping like 70 bucks to ship 100$ worth of rims lol
What is the widest tire I can run without worrying about rubbing anything I'm running a mild 318 so I don't need to worry about spinning I just want it to look good

Most Dart’s can handle a 245/60/15.
But the backspace on the rim has to be pretty much right on for that to work.
