What 385/65R22.5 means

In the size 385/65R22.5, 385 is the section width in millimeters (15.16 in), 65 is the aspect ratio — the sidewall stands 65% as tall as the tire is wide, or 250.2 mm (9.85 in) — R denotes radial construction, and 22.5 is the wheel diameter in inches. That works out to an overall diameter of about 42.20 inches, turning roughly 478 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 manufacturer lists the overall diameter of this specific tire as 42.8 inches — when clearance is tight, go by the published figure rather than the nominal size math.
