What 255/45R19 means
In the size 255/45R19, 255 is the section width in millimeters (10.04 in), 45 is the aspect ratio — the sidewall stands 45% as tall as the tire is wide, or 114.8 mm (4.52 in) — R denotes radial construction, and 19 is the wheel diameter in inches. That works out to an overall diameter of about 28.04 inches, turning roughly 719 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 28.2 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 104 — a maximum load of 1,984 lbs per tire. The speed symbol H corresponds to a maximum sustained speed of 130 mph.
Load Range E corresponds to a 10-ply rating.
