What 380/85R24 means

In the size 380/85R24, 380 is the section width in millimeters (14.96 in), 85 is the aspect ratio — the sidewall stands 85% as tall as the tire is wide, or 323.0 mm (12.72 in) — R denotes radial construction, and 24 is the wheel diameter in inches. That works out to an overall diameter of about 49.43 inches, turning roughly 408 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.
