What does the 120-load index on tires mean? A light truck tire with a load index of 120/116, for example, has a single tire load capacity of 3,086 pounds and a two-tire load capability of 2,756 pounds.

What is the load rating of a tire?
The load rating of the tire displays the weight a tire can carry. The product of the load capacity of a single tire and the number of tires determines the load carrying capacity of all the tires combined. The rating of 121 shows that it has a load capacity of 3297LBS. Multiply that by four tires (4 x 3,297 = 13,188 pounds) to get your vehicle's max load carrying capacity. Always remember to install tires that have a load index that is equal or greater than your original factory-installed tires.
What is the code for a truck tire?
A typical code on a Light Truck & SUV tire looks like; 35 (Diameter)x12.5 (Width)R20 (Rim Size) E (Ply Rating) and our tires will have another spot on the tire with Load Index and Speed Rating. A speed rating will be an alphabetic number ranging from L-Z stating how fast the tire is rated for. Load Index will be numeric and will run from 0 - 150. The load index is typically found next to the speed rating. The load index will tell you the load capacity of the tires and will typically be first before the speed rating. For instance, our Claw 35x12.5R20 E has a load index of 121 and a speed rating of Q. To understand the actual meaning of the code, you need to read a tire load capacity chart.
