Business To get the most out of your tiresmaximum mileage, safety and wearyou’ll need to keep up with proper tire repair. If you take a close look at your tires, you will notice a series of letters and numbers on the side of your tires. These numbers and letters have very specific meanings, unique information that is divided into three main sections. Visit your local auto shop and ask a tire specialist to "read" your tires. Three pieces of information are listed on your tires: 1. Specs. A set of letters and numbers that describe the fundamental characteristics of the tire: > Tire Type – This designates the type of vehicle the tire fits–P for passenger metric, LT for light truck, T for temporary spare, and ST for special trailers. If your tire has no letter, this signifies a Euro "metric" size. > Tire Width – Also called Section Width, this is the width of the tire in millimeters (it originated in Europe which uses the metric system) measured from a tire’s widest point of its outer sidewall to the widest point of its inner sidewall. > Aspect Ratio – This identifies the relationship of the tire’s sidewall height to the tire’s width. The lower the ratio, the smaller the sidewall height, which means better cornering, but a rougher ride. > Construction – This is the tire’s internal construction, or R for "radial." Other letters used are D for diagonal construction, and B for belted. > Wheel Diameter – This number (in inches) indicates the size of the wheel that the tire is designed to fit on. > Load Index – This indicates how much weight the tire is certified to carry at maximum safe inflation. A load index chart will show you the assigned value that corresponds with the tire’s actual load capacity. > Speed Rating – The maximum safe speed at which a tire is certified to carry a load under specified conditions, which is also found on a speed rating chart. 2. DOT (Department of Transportation) Safety Code. This code indicates that your tire complies with all DOT safety standards, together with the tire’s identification number (consisting of the tire’s manufacturer and plant code), and also the week and year the tire was manufactured. 3. UTQG (Uniform Tire Quality Grading) Code. The UTQG was established by the National Highway Traffic Safety Administration (NHTSA) to test tires following government prescribed test methods. Tires are graded on three componentstread wear, traction, and temperature. Wondering what kind of tires are on your vehicle?
