What 185/55R15 means
In the size 185/55R15, 185 is the section width in millimeters (7.28 in), 55 is the aspect ratio — the sidewall stands 55% as tall as the tire is wide, or 101.8 mm (4.01 in) — R denotes radial construction, and 15 is the wheel diameter in inches. That works out to an overall diameter of about 23.01 inches, turning roughly 876 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 82 — a maximum load of 1,047 lbs per tire. The speed symbol H corresponds to a maximum sustained speed of 130 mph.
