The load index of a tire represents the maximum weight that each tire can safely carry when properly inflated. This value is usually printed on the sidewall of the tire, along with other important information like speed rating and tire dimensions. A load index of 112 indicates that the tire can carry up to 2,469 pounds (or approximately 1,120 kilograms). It's important to ensure that the load index of the tires you choose meets or exceeds the requirements for your vehicle. You can usually find this information in your vehicle's owner's manual or on a sticker located on the driver's side door jamb.
