When the ATV tire is fully inflated, the first, second, and third numbers correspond to the overall height, width, and wheel (rim) diameter. For example, 24x8-12 denotes a tire that is 24 inches tall, 8 inches broad, and 12-inch wheel diameter. In some cases, the \\"-\\" is replaced with an \\"x,\\" as in 24x8x12 instead of 24x8-12.
