What 155/80R13 means
In the size 155/80R13, 155 is the section width in millimeters (6.10 in), 80 is the aspect ratio — the sidewall stands 80% as tall as the tire is wide, or 124.0 mm (4.88 in) — R denotes radial construction, and 13 is the wheel diameter in inches. That works out to an overall diameter of about 22.76 inches, turning roughly 886 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 13 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 79 — a maximum load of 963 lbs per tire. The speed symbol S corresponds to a maximum sustained speed of 112 mph.
