Tire Load Index Xplained – Deep Dive

What do the digits on the sides of your vehicle's tires mean for you? Let's take a deep dive into the topic and understand more about the essential specifications about the tire index. 



Simply put, the tire load index is the allocated number that correlates to the maximum amount of weight that the tire can bear when it has been completely inflated. To put it across in a more simple term one may say, the greater the number of the tire load index, the higher will be the weight carrying capacity or the load carrying capacity of the tire. As such it is never advisable to choose a tire with a smaller load index than the authentic factory specs because then the tire would not be able to bear the load capacity of the original. 

Let's try and understand how the load index of the tire corresponds to its capacity to carry the weight with the help of a metaphor. We'll take an example of a thin person having a load index of 60. In the gym, he can lift dumbbells weighing 20lbs compared to a bodybuilder, with a load index of 100, who can lift dumbbell weighing 120lbs. So, in other words, the load index is just telling you how much total amount of weight/burden/load the tire of your respective vehicle can support.

Let's take one more example in reference to a person who is looking to buy tires. Suppose, the tire he is planning to buy has a tire load index equal to 85. In that case, the tire can support a total of 1,135 pounds at the fullest air pressure of the tire. If this is multiplied by 4, i.e. (4 x 1,135 = 4,540 lbs), 4,540 pounds will be the car's maximum load carrying capacity. It is for this reason alone one must keep in mind to never opt for a lesser tire load index than the original one provided from the factory along with the car. 



As you might have understood by now, tire load index is essential to take note of and determine while shopping for your new tires. When you are about to make your next purchase decision for the tires, make sure you select the one that can support your vehicle's GVWR( Gross Vehicle Weight Rating), which is given in your vehicle's manual. As long as the maximum load carrying capacity as calculated above is more than your GVWR, the tires should be a perfect fit for your vehicle.
