What 305/70R18 means

In the size 305/70R18, 305 is the section width in millimeters (12.01 in), 70 is the aspect ratio — the sidewall stands 70% as tall as the tire is wide, or 213.5 mm (8.41 in) — R denotes radial construction, and 18 is the wheel diameter in inches. That works out to an overall diameter of about 34.81 inches, turning roughly 579 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 126 — a maximum load of 3,748 lbs per tire, or 123 (3,417 lbs) per tire when mounted as duals. The speed symbol R corresponds to a maximum sustained speed of 106 mph.

Load Range E corresponds to a 10-ply rating.
