What 305/45R22 means
In the size 305/45R22, 305 is the section width in millimeters (12.01 in), 45 is the aspect ratio — the sidewall stands 45% as tall as the tire is wide, or 137.2 mm (5.40 in) — R denotes radial construction, and 22 is the wheel diameter in inches. That works out to an overall diameter of about 32.81 inches, turning roughly 615 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.
The manufacturer lists the overall diameter of this specific tire as 22 inches — when clearance is tight, go by the published figure rather than the nominal size math.
The service description on this tire decodes to a load index of 118 — a maximum load of 2,910 lbs per tire. The speed symbol V corresponds to a maximum sustained speed of 149 mph.
