Each figure is rounded separately, so related figures can differ in the last digit.

These are size-code figures only. Whether a size fits, clears and carries your load depends on your vehicle and the tire, so check with a tire shop.

What changes

Only the section width changes, from 9.65 in to 10.43 in. The aspect ratio is a percentage of the width, so each sidewall grows with it, by 0.59 in, and the 265/75R16 ends up 1.18 in taller overall.

Makers' own measured diameters run 30.1 to 30.74 in for the 245/75R16 and 31.65 to 31.89 in for the 265/75R16, against the calculated 30.47 in and 31.65 in. Real tires vary by brand and tread design; the figures in the table come from the size code alone.
