What 285/75R24 means

In the size 285/75R24, 285 is the section width in millimeters (11.22 in), 75 is the aspect ratio — the sidewall stands 75% as tall as the tire is wide, or 213.8 mm (8.42 in) — R denotes radial construction, and 24 is the wheel diameter in inches. That works out to an overall diameter of about 40.83 inches, turning roughly 494 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 24.5 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 147 — a maximum load of 6,779 lbs per tire. The speed symbol M corresponds to a maximum sustained speed of 81 mph.

Load Range H corresponds to a 16-ply rating.
