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 7.68 in to 8.07 in. The aspect ratio is a percentage of the width, so each sidewall grows with it, by 0.26 in, and the 205/65R15 ends up 0.51 in taller overall.

Makers' own measured diameters run 25.0 in for the 195/65R15, against the calculated 24.98 in. Real tires vary by brand and tread design; the figures in the table come from the size code alone.
