What size tires will fit on stock dart 15" wheels?

I'm running 15x6 on the front with 205/65/15s and 15x8 0n the back with MT Sportsman S/R LT 26x10R15 on the back.Can't remember B/S what ever the standard is for 15x8 sbp.Picked them up at Summit not a special order.No rubbing issues,but it is pretty close on drivers side as my rear end isn't centered real well. The wheels Wheel Vintiqes steelies.If your using them and running dog dishes you'll have to grind the nubs that hold the cap.Not stamped deep enough and the caps pop off real easy.Unless they've changed their dies.
