What 185/80R13 means

In the size 185/80R13, 185 is the section width in millimeters (7.28 in), 80 is the aspect ratio — the sidewall stands 80% as tall as the tire is wide, or 148.0 mm (5.83 in) — R denotes radial construction, and 13 is the wheel diameter in inches. That works out to an overall diameter of about 24.65 inches, turning roughly 818 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 service description on this tire decodes to a load index of 94 — a maximum load of 1,477 lbs per tire, or 89 (1,279 lbs) per tire when mounted as duals. The speed symbol M corresponds to a maximum sustained speed of 81 mph.
