What 365/80R20 means

In the size 365/80R20, 365 is the section width in millimeters (14.37 in), 80 is the aspect ratio — the sidewall stands 80% as tall as the tire is wide, or 292.0 mm (11.50 in) — R denotes radial construction, and 20 is the wheel diameter in inches. That works out to an overall diameter of about 42.99 inches, turning roughly 469 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 158 — a maximum load of 9,370 lbs per tire. The speed symbol K corresponds to a maximum sustained speed of 68 mph.
