The numbers on the wall of the tyre show the size and aspect ratio of the tyre. The aspect ratio is the ratio between the tyres width and its side wall height. That is, a 205/60/15 size tyre has a 60% aspect ratio which means its side wall height is 60% of its width which is 205mm. Note that this is a ratio, not an absolute measurement so a 205/60 has a different side wall height measurement to a 195/60 even though the ratio is the same. The 15 refers to the wheel size in inches.
