Specifically on my small motorhome I have Hankook Dynapro HT RH12 195/75R16 tires, ( which in remote areas are hard to come by in a timely fashion). Other manufacturers of this size tire with same load characteristics all seem to be spec'd at .4 to .5 inches smaller outer diameter.
Are you sure about the size difference?
The tire size is literally that, the size of the tire. In your case a 195/75R16 is 195mm wide with a sidewall being 75% of that which is 147mm.
That means by definition it will have an 86.4” circumference.
