What 305/35R21 means

In the size 305/35R21, 305 is the section width in millimeters (12.01 in), 35 is the aspect ratio — the sidewall stands 35% as tall as the tire is wide, or 106.8 mm (4.20 in) — R denotes radial construction, and 21 is the wheel diameter in inches. That works out to an overall diameter of about 29.41 inches, turning roughly 686 revolutions per mile.
