If you’re upgrading your truck or Jeep with new wheels and tires or looking for rim tire financing with no credit check, it’s essential to understand load rating. Choosing tires with the right load rating ensures safety, performance, and durability. So, what exactly is load rating on tires, and why is it important?

Off-Road Rim Financing offers a variety of wheels, tires, and accessories for trucks and Jeeps. In this guide, we’ll explain what the load rating on tires means and how it impacts your vehicle’s performance.

Understanding Load Ratings on Vehicle Tires

A tire’s load rating refers to the amount of weight it can safely support when properly inflated. To find yours, you’ll have to locate the load index, a numerical value found on the tire sidewall markings.

Each load index corresponds to a specific maximum load capacity in pounds. Here’s what that looks like in real numbers:

  • A load index of 80 supports up to 992 lbs per tire.
  • A load index of 100 supports up to 1,764 lbs per tire.
  • A load index of 121 supports up to 3,197 lbs per tire.

Exceeding the maximum loan can cause premature wear, blowouts, or handling problems. 

How To Read Tire Sidewall Markings for Load Rating

What is a load rating on tires? How can you locate it?

You’ll find your tire’s load rating on the sidewall, along with other important information such as size, speed rating, and ply rating. Understanding these markings is essential when determining the load rating on tires and making an informed decision when upgrading your tires.

For example, a tire marked as LT275/70R18 125/122S provides the following information:

  • LT – Light Truck tire
  • 275/70R18 – Tire width, aspect ratio, and wheel diameter
  • 125/122 – Load index (supports up to 3,640 lbs per tire at proper inflation pressure)
  • S – Speed rating

Decoding these markings ensures you choose the right tires for your vehicle’s needs.

The Importance of Load Range and Inflation Pressure

The load range of a tire refers to its strength and weight capacity, usually represented by letters such as C, D, E, or F. The higher the letter, the stronger the tire. Some examples include:

  • Load Range C – 6-ply rating, suitable for light-duty trucks
  • Load Range D – 8-ply rating, better for heavier loads
  • Load Range E – 10-ply rating, ideal for heavy-duty use

Keeping your tires at the right inflation pressure is just as important as choosing the correct load rating. Regularly checking your pressure as part of basic tire safety ensures better performance and longevity.
