Use the tire load index chart to see how much weight your tire can support
The OTR tire load index lets you know the load–carrying capacity of a tire. In other words, it’s the amount of weight your tire can support safely.
The LOAD INDEX is an international numerical code for the maximum load a tire can carry at the speed indicated by its speed symbol under service conditions specified by tires brands.
For example, if a tire has a load index of 92, it can support 1,389 pounds or 630 kg at maximum air pressure. Multiply that by four tires (4 x 1,389 = 5,556 pounds / 2520,16 kg) to get your car’s maximum load–carrying capacity. Never install tires with a lower load–carrying capacity than the original tires that were factory–installed on your vehicle.
