What 275/40R20 means
In the size 275/40R20, 275 is the section width in millimeters (10.83 in), 40 is the aspect ratio — the sidewall stands 40% as tall as the tire is wide, or 110.0 mm (4.33 in) — R denotes radial construction, and 20 is the wheel diameter in inches. That works out to an overall diameter of about 28.66 inches, turning roughly 704 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 106 — a maximum load of 2,094 lbs per tire. The speed symbol Y corresponds to a maximum sustained speed of 186 mph.
