What 320/70R15 means
In the size 320/70R15, 320 is the section width in millimeters (12.60 in), 70 is the aspect ratio — the sidewall stands 70% as tall as the tire is wide, or 224.0 mm (8.82 in) — R denotes radial construction, and 15 is the wheel diameter in inches. That works out to an overall diameter of about 32.64 inches, turning roughly 618 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 146 — a maximum load of 6,614 lbs per tire.
