The 185, 165 etc is the nominal width of the tread in millimeters. The 75, 70,
or 65 etc is the aspect ratio or the height of the sidewall as a percentage of
the tread width. thus a 185-R70 will have a nominal tread width of 185 mm or
7.28" with a sidewall height of approximately 129 mm or 5.1". For some reason
the actual manufacturers' dimensions vary somewhat for the same nominal
sizes.
