What is Tire Load Index?


tire sidewall code

Tire load index determines the maximum weight a tire can safely support once it's properly inflated. As shown in the graphic above, this number is on the sidewall to the right of the tire size rating, but the load index can also be found on your vehicle's placard or in the owner's manual. Most standard light truck and passenger tires have tire load index ratings between 70 and 110, but drivers should consider a higher tire load index rating if they consistently haul heavy equipment.

Below is a load index chart that converts common ratings into their proper load capacities. When choosing new tires, it's important to have a load index that is at least as high as the one listed on the sidewall or doorjamb placard.
