What does load index mean on a tire?

The load index is an assigned numerical code ranging from 0 to 150 that corresponds to the maximum weight a single tire can safely support when fully inflated to its maximum pressure.

Can I use a tire with a lower load index?

Never. You must always replace tires with a load index equal to or greater than the original equipment (OEM) factory tires. Installing a tire with a lower load index can lead to sudden tire failure under heavy load.

Is tire load rating per tire or for the whole car?

The load index number printed on the sidewall indicates the capacity for one single tire. To find your total theoretical tire capacity, multiply that number by the four wheels on your vehicle.

What is the difference between Load Range and Load Index?

Load Index is a precise mathematical weight limit (e.g., 116 = 2,756 lbs). Load Range is a letter system (C, D, E) used mostly on Light Truck (LT) tires to indicate the tire's ply-rating toughness and the maximum air pressure it can hold.

Does increasing tire pressure increase load capacity?

Yes, up to the maximum limit printed on the tire sidewall. A tire only achieves its full rated Load Index capacity when it is inflated to its maximum PSI. If you run lower tire pressure for comfort, your load capacity decreases.

Quick Answer

A tire with a load index of 116 can safely carry a maximum weight of 2,756 pounds (1,250 kg) when fully inflated to its maximum PSI. For a standard four-wheeled truck, this provides a combined maximum theoretical tire load capacity of 11,024 pounds across all four corners.

How Load Index Works

N/A — Standardized ETRTO/TRA logarithmic table lookup | Total Capacity = Load per tire × 4

Load Index = 2 or 3 digit number located just before the speed rating letter
Capacity = achieved only at the tire's maximum rated PSI; lower pressure reduces capacity
Total Vehicle Capacity = (Load per tire × 4)
Example: Input "100" → Output: 1,764 lbs. 1,764 × 4 = 7,056 lbs total tire capacity
