"185 65R15" is a tire size designation that provides information about the tire's width, aspect ratio, construction, and inner rim diameter. Here's what each part of the designation means:
-

-
65 - This is the aspect ratio, which is the ratio of the tire's height to its width. In this case, the tire's height is 65% of its width. So, if the tire is 185 millimeters wide, its height is 185 x 0.65 = 120.25 millimeters.
