Did you know that there’s a series of numbers on the side of your tire that tells you how much weight each of the tires can carry? This number is called the Tire Load Index. This is a numerical code created as a guide to understanding the maximum weight each tire can support when it’s properly inflated to the manufacturer’s recommended tire pressure. The indexes are translated to weight. Meaning that the higher a tire’s load index number is, the greater its load-carrying capacity. So how can you find your tire’s load index? It’s located on your tire’s sidewall and listed after the tire’s size. Passenger tires will feature one load index number on its sidewall. To help understand how your load index number associates to the weight in pounds that a tire can carry when properly inflated, view our helpful chart online. Goodyear.com. Tire buying, simplified..
