What 305/30R19 means
In the size 305/30R19, 305 is the section width in millimeters (12.01 in), 30 is the aspect ratio — the sidewall stands 30% as tall as the tire is wide, or 91.5 mm (3.60 in) — R denotes radial construction, and 19 is the wheel diameter in inches. That works out to an overall diameter of about 26.20 inches, turning roughly 770 revolutions per mile. Overall diameter is what matters for speedometer accuracy and clearance when you change sizes, so compare it — not just the width — against your current tire.
