What 285/40R19 means
In the size 285/40R19, 285 is the section width in millimeters (11.22 in), 40 is the aspect ratio — the sidewall stands 40% as tall as the tire is wide, or 114.0 mm (4.49 in) — R denotes radial construction, and 19 is the wheel diameter in inches. That works out to an overall diameter of about 27.98 inches, turning roughly 721 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 103 — a maximum load of 1,929 lbs per tire. The speed symbol W corresponds to a maximum sustained speed of 168 mph.
