What 245/70R16 means
In the size 245/70R16, 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 16 is the wheel diameter in inches. That works out to an overall diameter of about 29.50 inches, turning roughly 684 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.
