The markings on the side of an automotive tire relate to the tire size, ratings and compatibility codes. When looking at the sidewall of a tire, the series of letters and numbers on it can be confusing but is fairly simple to decode. The sidewall series can tell you your tire size, manufacturer, speed rating and many other important pieces of information. Other information that appears on the side of your tires includes load and tire pressure markings, special weather ratings and construction type.
