Load index is an assigned number that corresponds with the load-carrying capacity of a tire. Most passenger car tire load indexes range from 75 to 100, but a few carry more. You'll also find the maximum load elsewhere on the tire sidewall, both in lbs and kg.
Load index is a numerical code which shows the maximum load a single tyre can carry at the speed shown by it Speed Rating Symbol. There is often an optional reference which shows the load a twinned pair of tyres can carry at the speed shown by it Speed Rating Symbol. Examples: Figure 3.
