What 315/40R21 means

In the size 315/40R21, 315 is the section width in millimeters (12.40 in), 40 is the aspect ratio — the sidewall stands 40% as tall as the tire is wide, or 126.0 mm (4.96 in) — R denotes radial construction, and 21 is the wheel diameter in inches. That works out to an overall diameter of about 30.92 inches, turning roughly 652 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.
