What 325/30R20 means
In the size 325/30R20, 325 is the section width in millimeters (12.80 in), 30 is the aspect ratio — the sidewall stands 30% as tall as the tire is wide, or 97.5 mm (3.84 in) — R denotes radial construction, and 20 is the wheel diameter in inches. That works out to an overall diameter of about 27.68 inches, turning roughly 729 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.
