What 285/35R20 means

In the size 285/35R20, 285 is the section width in millimeters (11.22 in), 35 is the aspect ratio — the sidewall stands 35% as tall as the tire is wide, or 99.8 mm (3.93 in) — R denotes radial construction, and 20 is the wheel diameter in inches. That works out to an overall diameter of about 27.85 inches, turning roughly 724 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 104 — a maximum load of 1,984 lbs per tire. The speed symbol Y corresponds to a maximum sustained speed of 186 mph.
