What 175/50R15 means
In the size 175/50R15, 175 is the section width in millimeters (6.89 in), 50 is the aspect ratio — the sidewall stands 50% as tall as the tire is wide, or 87.5 mm (3.44 in) — R denotes radial construction, and 15 is the wheel diameter in inches. That works out to an overall diameter of about 21.89 inches, turning roughly 921 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 75 — a maximum load of 853 lbs per tire. The speed symbol H corresponds to a maximum sustained speed of 130 mph.
