I am asking because I've read two different figures for my '66 Plymouth Fury.
A Car Life road test lists wheel size as 14x6" with 14x5.5" as an option for a '66 Plymouth Fury VIP (383).
But the 1966 Plymouth Fury brochure lists 14x5" as wheel size. (Wagons: 14x6".)
How are they measured and can they be measured with the tire on?
