Tire size change.8R19.5's to 225/70R19.5

I just purchased new tires for my 1984 29' Brougham. with the advice of the tire salesman I bought the B F Goodrich 225/70r19.5's to replace my
old 8R19.5's. He said that a lot of people were converting to this tire
and that it was only about a half inch shorter. I was concerned about my gas mileage and speedometer accuracy, he said I would get better mileage
with this tire. when I got the RV home I compared it side by side to an 8R19.5 and it seems to be more than a half inch smaller. Did I get steered in the wrong direction?
