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 11.22 in to 11.61 in. The aspect ratio is a percentage of the width, so each sidewall grows with it, by 0.26 in, and the 295/65R20 ends up 0.51 in taller overall.

Makers' own measured diameters run 34.57 to 34.6 in for the 285/65R20 and 35.12 to 35.47 in for the 295/65R20, against the calculated 34.59 in and 35.10 in. Real tires vary by brand and tread design; the figures in the table come from the size code alone.
