Tire load index chart with corresponding maximum tire load capacity.
What is Tire Load Index?
Tire load index is a numerical value assigned to a tire that corresponds to the maximum weight it can support when inflated to its maximum load sustaining pressure. Tire load index lets you know the load carrying capacity of a tire, or the amount of weight a tire can support safely.
Where Can I Find My Tire Load Index?
Tire load index is imprinted on tire sidewall as a part of the tire size service description right before tire speed rating.
Why Is Tire Load Index Important?
For most passenger cars and light trucks, tire load ratings range from 70 to 130. The higher the tire's load index, the greater its load carrying capacity and more weight it can carry.
Original equipment tires that were factory equipped on your vehicle have a proper tire load index that was designated to support vehicle's weight. When replacing original equipment tires, make sure that new tires have the same tire load index or higher. Never install tires with lower load carrying capacity than the original equipment tires.
Vehicle's GVWR (Gross Vehicle Weight Rating) is the maximum overall weight of a vehicle as specified by its manufacturer including its chassis, body, engine, fuel, accessories, passengers and cargo. Tires equipped on your vehicle should be able to support the weight they are carrying. Never overload a tire beyond the maximum weight that corresponds to its load index. Overloading tires can cause uneven tread wear, structural damage or tire blowout.
Check the vehicle’s manual to find its Gross Vehicle Weight Rating, original equipment tire sizes and tire load ratings.
Some tires have a dual tire load index with two numbers, commonly used on light trucks and pickups with dual rear wheels. The first number indicates tire load carrying capacity for a single-wheel rear axle, and the second number applies for dual rear wheel applications.
