What 235/80R17 means

In the size 235/80R17, 235 is the section width in millimeters (9.25 in), 80 is the aspect ratio — the sidewall stands 80% as tall as the tire is wide, or 188.0 mm (7.40 in) — R denotes radial construction, and 17 is the wheel diameter in inches. That works out to an overall diameter of about 31.80 inches, turning roughly 634 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 120 — a maximum load of 3,086 lbs per tire, or 117 (2,833 lbs) per tire when mounted as duals. The speed symbol R corresponds to a maximum sustained speed of 106 mph.
