Back in the day they did bucko...thats is why the oldster has a rear stand on it and the fender has a hinge that lets the fender flod up to help in removal. After this weekends ride, I don't think I will ever wear out the skins on it...
. Tires were the same size front and rear for quite a few years.. 
I recall from the 1960’s through the early ‘80’s, the Firestone and Goodyear Super Eagles as well as the later Speed Grip tires were the same for the front and rear in the 5.00 and 5.10x16 sizes.
As I remember it, the hinged rear fender was used through 1978 on the FLH; although with all of the goodies festooned on the back end of the later machines, most folks didn’t use the hinge, but simply raised the motorcycle and dropped the wheel out the bottom.
Rotating the tires was not unheard of, although not real common through the ‘60’s. The wheel assemblies were the same front and rear. Removing the wheel lugs allows the brake drum to be separated from the wheel, making the swap relatively easy. In your wildest hallucination, you couldn’t imagine a motorcycle handling worse than they did with a worn, squared off rear tire running up front. It was an experience worth owning.
