What 125/90R16 means

In the size 125/90R16, 125 is the section width in millimeters (4.92 in), 90 is the aspect ratio — the sidewall stands 90% as tall as the tire is wide, or 112.5 mm (4.43 in) — R denotes radial construction, and 16 is the wheel diameter in inches. That works out to an overall diameter of about 24.86 inches, turning roughly 811 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 98 — a maximum load of 1,653 lbs per tire. The speed symbol M corresponds to a maximum sustained speed of 81 mph.
