The aspect ratio is the ratio between the tread width and the height of the walls. Eg, a 205-60 X (say) 16 tyre has a read width of 205 mm and a wall height of 205x60%= 123mm. 16" is 406mm so the inflated tyre would be 406+(2x 123)+ 652mm diameter. The higher the walls of a tyre, the more flexing you get as you corner and the more it will want to wander in a cross wind etc
