What 420/70R28 means

In the size 420/70R28, 420 is the section width in millimeters (16.54 in), 70 is the aspect ratio — the sidewall stands 70% as tall as the tire is wide, or 294.0 mm (11.57 in) — R denotes radial construction, and 28 is the wheel diameter in inches. That works out to an overall diameter of about 51.15 inches, turning roughly 394 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 52.7 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 133 — a maximum load of 4,542 lbs per tire.
