What 425/65R22.5 means

In the size 425/65R22.5, 425 is the section width in millimeters (16.73 in), 65 is the aspect ratio — the sidewall stands 65% as tall as the tire is wide, or 276.2 mm (10.88 in) — R denotes radial construction, and 22.5 is the wheel diameter in inches. That works out to an overall diameter of about 44.25 inches, turning roughly 456 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 44.09 inches — when clearance is tight, go by the published figure rather than the nominal size math.
