What 245/40R21 means

In the size 245/40R21, 245 is the section width in millimeters (9.65 in), 40 is the aspect ratio — the sidewall stands 40% as tall as the tire is wide, or 98.0 mm (3.86 in) — R denotes radial construction, and 21 is the wheel diameter in inches. That works out to an overall diameter of about 28.72 inches, turning roughly 702 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 22.96 inches — when clearance is tight, go by the published figure rather than the nominal size math.
