What 245/70R19.5 means
In the size 245/70R19.5, 245 is the section width in millimeters (9.65 in), 70 is the aspect ratio — the sidewall stands 70% as tall as the tire is wide, or 171.5 mm (6.75 in) — R denotes radial construction, and 19.5 is the wheel diameter in inches. That works out to an overall diameter of about 33.00 inches, turning roughly 611 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 133 — a maximum load of 4,542 lbs per tire, or 131 (4,299 lbs) per tire when mounted as duals. The speed symbol M corresponds to a maximum sustained speed of 81 mph.
Load Range G corresponds to a 14-ply rating.
