What Is Tire Load Index and Why Does It Matter?

When shopping for new tires, most people focus on size, brand, and price—but tire load index is just as critical. If you’re not sure what it means or how to find it, you’re not alone. In this article, we’ll break down everything you need to know about tire load index and how to locate it on your vehicle or tire sidewall.

What Is the Tire Load Index?

The load index is a numerical code that represents the maximum weight a tire can safely support when properly inflated. It’s usually a two- or three-digit number (like 91, 95, or 104) found next to the tire’s speed rating.

For example:

  • 225/65R17 102T → “102” is the load index.
  • A load index of 102 means the tire can carry up to 1,874 pounds (850 kg).

Use a load index chart to see what your number translates to in pounds or kilograms.

Where to Find the Load Index?

You can find the load index in several places:

  1. On the Tire Sidewall
    Look for a string of numbers and letters (like 225/60R16 98H). The load index is just before the speed rating letter.
  2. Driver’s Side Door Jamb
    Open the driver’s side door and check the tire information placard. It typically lists the recommended tire size, pressure, and load rating.
  3. Vehicle Owner’s Manual
    Your car’s manual includes factory-recommended tire specifications, including load index.

Why It Matters

Choosing the correct load index ensures:

  • Safety: Overloaded tires can overheat and fail while driving.
  • Warranty Compliance: Using the wrong load index may void your tire warranty.
  • Insurance Coverage: Some insurers may deny claims if improper tires were used.

Never install tires with a lower load index than your vehicle requires. Higher is okay, but lower is unsafe.
