What 165/65R13 means
In the size 165/65R13, 165 is the section width in millimeters (6.50 in), 65 is the aspect ratio — the sidewall stands 65% as tall as the tire is wide, or 107.2 mm (4.22 in) — R denotes radial construction, and 13 is the wheel diameter in inches. That works out to an overall diameter of about 21.44 inches, turning roughly 940 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 77 — a maximum load of 908 lbs per tire. The speed symbol H corresponds to a maximum sustained speed of 130 mph.
