73 Duster Weld Pro Stars Offset?

I am wanting to put Weld Pro Stars on my 73 Duster...not sure if I need 15 inch or 14 inch on the front...thought about 14 x 6 with 205/60
Is there a 15 inch rim that is a little narrower such as 5 inches wide that will work without rubbing? What tires size I am going to do some driving on the highway so really don't want the real skinny front runners. I plan to put 270/60 x 15 on the rear. Thanks....Tim
