" Just divide the width in millimeters by 25.4 to get inches. To figure
" the sidewall height, multiply the width in mm by the "series" number
" with a decimal in front of it. A 195/78 has a sidewall height of 195 x
" .78 = 152.1 mm (6"), a 205/70 like I run 205 x .70 = 5.7". I said
" sidewall height, but that's really the total height of the tire from
" the rim to the center of the tread -- the tread bulges just a bit from
" the edge of the sidewall. I checked it on my car to make sure I'm
" correct! Total diameter is wheel size plus sidewall height x 2, on
" mine it's 15 + (5.7 x 2) = 25.4". 

there's another factor.  spec tire width is assuming a particular rim;
widen the rim by 1" and the actual tire width increases by 10mm.

reference rim for the 195/78s is probably 5.5", so running them on 7"
would make them an actual 210mm wide.

"   I am running 195 78 14 on my 65 w/a set of 14x7 Cragar Smoothies, 

btw 215/70s are almost precisely the same rolling diameter as 195/78s.
