good site there about tire size designations.
what they don't tell you is that ......
in a metric tire size where the aspect ratio is not stated.....
as in 185 R 14 C ........
is that the aspect ratio in that case is considred to be 80.
like 185 R 14 C and 185/80 R 14C tires would be the same size.

I have never seen /00 as a aspect ratio written anywhere.
What i have seen is either no aspect ratio.........or XXX/78 or XXX/80.
When I got some 195 R 15 C tires recently.............which have a very tall
aspect ratio......they told me they are "/80"  as far as aspect ratio is
concerned.
and of course.......
the lower the aspect ratio number, the lower and relatively wider the tire
is.  A /30 aspect ratio, for example  tire is quite low , very short
distance from rim to pavement.
'normal' aspect ratio on a vanagon  tire would be 70, 75, 65, sometimes even
60.

this is interesting from that tire size page :
" If the section width ended in zero (e.g., 7.00-14 or 7.50-14), the tire
had a common aspect ratio of about 92. For section widths not ending in zero
(e.g., 8.25-15), the tire was considered "low profile" with an aspect ratio
of about 82."

never saw that anywhere before.
an 82 aspect ratio is sure not 'low profile' these days !
