Check Your Tire's Sidewall: • With a little explanation it's easy to understand what all of the letters and numbers mean on your tire's sidewall. The numbers are indicators of the size, type, and performance of the tire. • Tire Type The letter "P" at the beginning of the "Tire Size" tells us the tire is a P-Metric tire, referring to tires made to certain standards within the United States, intended for Passenger vehicles. • If a tire size has no letters at the beginning, this indicates a Euro metric tire. P-Metric and Euro-Metric tires may have different load capacities. • The letters "LT," either at the beginning or at the end of the tire size indicate the tire was designed for light trucks. Vehicle manufacturers equip some light trucks with "LT" type tires. These tires generally require higher inflation pressures than passenger tires. • Consult your owner's manual or tire placard for the recommended tire size and inflation pressure for your vehicle. Tire Width is the width of the tire measured in millimeters from sidewall to sidewall. The first three-digit number in the tire size refers to the tire width. For instance, in a size P220/40 R17 tire, the width is 220 millimeters. Aspect Ratio is the ratio of the height of the tire's cross-section to its width. The two-digit number after the slash mark in a tire size is the aspect ratio. For example, in a size P220/40 R17 tire, the 40 means that the height is equal to 40% of the tire's width. The bigger the aspect ratio, the bigger the tire's sidewall will be. Construction. The letter "R" in a tire size stands for Radial, which means the layers run radially across the tire. Wheel Diameter is the size of the wheel measured from one end to the other. It tells us the size of the wheel that the tire is intended to fit. A size P220/40 R17 tire is made for a wheel with a 17 in diameter. Thanks for your support and do visit nitrio.com for more apps for your iOS devices.
