define tire load index
The load index is a number that corresponds to the physical load-handling weight of a tire in kilograms or pounds. The load index can be used as a cross reference to find the weight in pounds or kilos. For example, a load index of 105 corresponds to 2,039 pounds or 925 kilograms. This chart is found inside the vehicle's door jams and is available in tire replacement shops. The Tire Rack: Load Range Identification.
