Using the chart

How do I convert a metric tire size to inches?

Height = rim diameter + 2 × sidewall, where sidewall = width × aspect ratio ÷ 100, converted from millimetres by dividing by 25.4. For 265/70R17 that is 17 + 2 × (265 × 0.70 ÷ 25.4) = 31.6 inches.

Why does my tire measure a little less than the chart?

The chart gives the unloaded design size. A mounted tire carrying the vehicle's weight flattens slightly at the bottom, and tread wear takes off a few tenths of an inch over its life.
