What 315/75R16 means

In the size 315/75R16, 315 is the section width in millimeters (12.40 in), 75 is the aspect ratio — the sidewall stands 75% as tall as the tire is wide, or 236.2 mm (9.30 in) — R denotes radial construction, and 16 is the wheel diameter in inches. That works out to an overall diameter of about 34.60 inches, turning roughly 583 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 16 inches — when clearance is tight, go by the published figure rather than the nominal size math.

The service description on this tire decodes to a load index of 121 — a maximum load of 3,197 lbs per tire, or 118 (2,910 lbs) per tire when mounted as duals. The speed symbol Q corresponds to a maximum sustained speed of 99 mph.

Load Range D corresponds to a 8-ply rating.
