Mike:
As I recall, the older tire size system was pretty close to 82
profile when used in the current tire sizing system. So the original
185x15 red lines would be 185-82/R15 in today's tire sizes, which of
course rounds to 185-80/15. So to answer your question directly, yes
that is as close as you can get using the tire calculator.
I use 205-70/R15 on my car which gets pretty close to the
original, but is still slightly undersized.

I found the below website quite interesting. The visual representations
are even better than the stuff I found on the tire rack. I now see why
my 205 X 55 X 16s cause my speedo to read 70 when I'm doing 65. For the
purposes of comparison in this link is 185 X 80 X 15s the closest we can
get to the original TR 6 tire size?

While surfing the triumphowners web site I came across a link to a
site
where someone has set up a page that graphically compares wheel and
tire sizes against each other. Pretty neat. Thought others might get
a kick out of it. There is other interesting information at the site
also.
