What 255/50R20 means

In the size 255/50R20, 255 is the section width in millimeters (10.04 in), 50 is the aspect ratio — the sidewall stands 50% as tall as the tire is wide, or 127.5 mm (5.02 in) — R denotes radial construction, and 20 is the wheel diameter in inches. That works out to an overall diameter of about 30.04 inches, turning roughly 671 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 20 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 109 — a maximum load of 2,271 lbs per tire. The speed symbol H corresponds to a maximum sustained speed of 130 mph.
