1 TIRE & TUBE SECTION Knowing some basic facts about tire dimensions and sizes along with a few technical aspects of tire construction can help clear up much of the confusion many people have in understanding tires and tire sizes. There are up to 14 parts to a tire, and each one is subjected to different stresses and performance requirements. About 89% of a tire is rubber compound. The remainder consists of 8% ply and belt materials, and.5% steel wire used in the bead. Understanding the sizing of tires can be especially confusing. There are two popular methods of identifying lawn and garden tires. The first is overall diameter x section width x rim diameter. An example of a popular tire using these dimensions is a 16 x tire. The second popular method of designating tire sizes icludes section width x section height x rim diameter, for example 4.10/ The section width and section height are also used to size car passenger tires. For instance, a P05/75R14 tire size is explained this way: the P stands for passenger car tire; the 05 is the section width in millimeters; the 75 indicates the section height to section width ratio (%); the R stands for radial construction; and the 14 is the rim diameter in inches. DEFINITIONS: Bead - The inner portion of the tire which fits onto the rim and contains bands of wire to which tire plies are attached. Ply Rating - Index of tire strength; indicates maximum recommended load for specific types of service. Usually does not indicate actual number of cord plies in the tire as it did in the past. Diameter - The distance between the vertical portion of the rim flange. If the rim is too wide or too narrow the tire beads will not seat properly. As a general rule, the proper rim width for a tire will be 1 to 1 1 inches narrower than the section width of the tire, depending on the size of the tire. Section - The distance across a tire at its widest part when inflated but not under load (does not include protective bars or decorations). Section Height - The distance between tread crown and bead seat when tire is inflated but not under load. Tire & Association - An organization of manufacturers which develops standards for rim and tire dimensions, loads and inflation pressures. The Tire & Association has set an acceptable variance of 8% from their published dimensions for tire size designations. Because of this variance it is always prudent to be aware of the possibility of tread and dimensional differences when replacing tires. This becomes especially important when replacing tires on equipment where tire dimensions are critical to equipment performance.
