What 225/55R18 means

In the size 225/55R18, 225 is the section width in millimeters (8.86 in), 55 is the aspect ratio — the sidewall stands 55% as tall as the tire is wide, or 123.8 mm (4.87 in) — R denotes radial construction, and 18 is the wheel diameter in inches. That works out to an overall diameter of about 27.74 inches, turning roughly 727 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 28.2 inches — when clearance is tight, go by the published figure rather than the nominal size math.
