W123 ideal tire setup on 240d?

[Carbuff]

Hey folks my 1984 240d tire set up is the w124 intra eightbhole 15x7? Wheels with 195/65/15 tires...tires have become old and hard...I have just replaced the front suspension. I am being advised to go back to 14 by some, other who say stick to current size and some who say issue if I go to 205/60/15.... As it is the same diff as original 14 setup?.....confused

Yes aware of that but get confused when it comes to the offset and inset...I believe the w123 came in 175/70/14 or was it 185/70/14 for the non power steering models...although can't confirm this as I have seen them on power steering models as well ...and I believe there were a 195's on 14's from the factory as well!!!?...so don't know where start...pls help if you know..as most people tell me that my current setup 195/65/15 is the same rolling radius as factory and going for a 205/60/15 would the same set up although wider....
