The load index indicates the load-carrying capacity of a tire. In other words, it tells you how much weight your tire can support. For example, if a tire has a load index of 92, it can support 1,389 pounds at maximum air pressure. Multiply that by four tires (4 x 1,389 = 5,556 pounds) to get your car’s maximum load-carrying capacity. Never install tires with a lower load carrying capacity than the tires originally installed on your car in the factory.
