What 225/40R18 means
In the size 225/40R18, 225 is the section width in millimeters (8.86 in), 40 is the aspect ratio — the sidewall stands 40% as tall as the tire is wide, or 90.0 mm (3.54 in) — R denotes radial construction, and 18 is the wheel diameter in inches. That works out to an overall diameter of about 25.09 inches, turning roughly 804 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.
