What 445/65R22.5 means
In the size 445/65R22.5, 445 is the section width in millimeters (17.52 in), 65 is the aspect ratio — the sidewall stands 65% as tall as the tire is wide, or 289.2 mm (11.39 in) — R denotes radial construction, and 22.5 is the wheel diameter in inches. That works out to an overall diameter of about 45.28 inches, turning roughly 445 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.
Load Range L corresponds to a 20-ply rating.
