What 315/80R22.5 means

In the size 315/80R22.5, 315 is the section width in millimeters (12.40 in), 80 is the aspect ratio — the sidewall stands 80% as tall as the tire is wide, or 252.0 mm (9.92 in) — R denotes radial construction, and 22.5 is the wheel diameter in inches. That works out to an overall diameter of about 42.34 inches, turning roughly 476 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 156 — a maximum load of 8,818 lbs per tire, or 150 (7,385 lbs) per tire when mounted as duals. The speed symbol K corresponds to a maximum sustained speed of 68 mph.

Load Range L corresponds to a 20-ply rating.
