Ellen found the Hankook pdf:

Good thing--I had width mixed up with depth in my
extract, which should have been:
                 tread depth     revs/mile       overall dia
185             11.5              812             25.6
195             11.0              790             26.3
(and a dia off, too.  Don't trust what I write....  ;-)
