What 245/25R21 means

In the size 245/25R21, 245 is the section width in millimeters (9.65 in), 25 is the aspect ratio — the sidewall stands 25% as tall as the tire is wide, or 61.2 mm (2.41 in) — R denotes radial construction, and 21 is the wheel diameter in inches. That works out to an overall diameter of about 25.82 inches, turning roughly 781 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 service description on this tire decodes to a load index of 86 — a maximum load of 1,168 lbs per tire. The speed symbol W corresponds to a maximum sustained speed of 168 mph.
