What the Tire Load Index Means

The tire load index is a number found on the tire sidewall that represents the maximum weight a single tire can safely carry when properly inflated. Each load index corresponds to a standardized weight rating measured in pounds. A higher number indicates a higher load carrying capacity.

Where to Find the Load Index

The load index appears on the tire sidewall near the tire size information and speed rating. Your vehicle manufacturer also lists recommended tire specifications on the driver side door jamb placard and in the owner’s manual.

Why Tire Load Index Is Important

Tires with the correct load index support proper braking, cornering, and overall stability. Using tires that are not rated for your vehicle’s weight can lead to uneven wear, reduced handling, and a higher risk of tire failure. This is especially important for trucks, SUVs, and vehicles that frequently haul cargo or tow.

Choosing the Right Load Index

When replacing tires, always choose a tire with the same or higher load index than the original equipment. Selecting a lower load index than recommended can negatively affect safety and performance. Professional guidance can help confirm the right tire for your driving needs.
