What 265/65R17 means
In the size 265/65R17, 265 is the section width in millimeters (10.43 in), 65 is the aspect ratio — the sidewall stands 65% as tall as the tire is wide, or 172.2 mm (6.78 in) — R denotes radial construction, and 17 is the wheel diameter in inches. That works out to an overall diameter of about 30.56 inches, turning roughly 660 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.
