What 195/45R17 means

In the size 195/45R17, 195 is the section width in millimeters (7.68 in), 45 is the aspect ratio — the sidewall stands 45% as tall as the tire is wide, or 87.8 mm (3.45 in) — R denotes radial construction, and 17 is the wheel diameter in inches. That works out to an overall diameter of about 23.91 inches, turning roughly 844 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 81 — a maximum load of 1,019 lbs per tire. The speed symbol W corresponds to a maximum sustained speed of 168 mph.
