The first number before the "x" indicates the tire's height or diameter when inflated and not under load. The middle number, that is the digits between the "x" and the "-," indicates the tire's width. So, the 15 x 600-6 specifically calls out the height as 15 inches. The standard 600-6 will be taller.
