Load Range H is a tire strength rating that tells you the maximum weight each tire can safely carry

Every tire has a load range printed on its sidewall — a letter from A to F (and sometimes beyond). Load Range H means that tire can support a maximum load of 1,500 pounds per tire when inflated to its rated pressure. The letter itself doesn't matter as much as understanding what weight your vehicle actually needs, and whether a tire marked H can handle it.

Load range is not the same as tire size. Two tires of the same size can have different load ranges. A tire labeled "LT245/75R16 Load Range E" and another labeled "LT245/75R16 Load Range H" are the same size but built differently inside — the H-rated tire has stronger internal construction and can carry more weight.

Most passenger cars use Load Range C or D. Light trucks and SUVs often use E, F, or H. If you're replacing tires on a truck or heavy vehicle, the owner's manual or the tire placard on your driver's door jamb will tell you which load range your vehicle needs.

Key Takeaways

  • Load Range H means each tire can carry up to 1,500 pounds at its rated pressure, making it suitable for heavier trucks and commercial vehicles.
  • Load range is printed on the tire sidewall and must match or exceed what your vehicle manufacturer specifies — using a lower range risks overloading.
  • The load range letter (A through H and beyond) reflects the tire's internal construction strength, not its size or tread pattern.
  • Your vehicle's tire placard, located on the driver's door jamb or in the owner's manual, shows the correct load range for your specific make and model.

Where to find the load range on your tire

The load range letter appears on the sidewall of every tire, usually near the tire size. It may be printed as "Load Range H" or abbreviated as "LR H". On some tires, especially light-truck tires, it appears after the tire size designation.

If you're standing at a tire shop or looking at a tire online, scan the sidewall image or the product description for the letters "LR" followed by a single letter. That letter is your load range. If you can't find it on the tire itself, the retailer's product page will list it in the specifications section.

How load range differs from load index

Load range and load index are two separate systems that measure weight capacity, and they're often confused. Load index is a number (like 104 or 120) that appears on passenger car tires and corresponds to a specific weight in pounds. Load range is a letter (A through H) that appears on light-truck tires and tells you the tire's structural strength category.

Passenger vehicles typically use load index. Light trucks, SUVs, and vehicles that tow or carry heavy loads typically use load range. If your tire has both a number and a letter on the sidewall, the letter is the load range and the number is the load index — they work together to define the tire's capacity.

What vehicles typically use Load Range H tires

Load Range H tires are common on full-size pickup trucks, heavy-duty SUVs, and commercial vehicles that regularly carry substantial weight or tow trailers. Vehicles like the Ford F-250, Chevrolet Silverado 2500, and Ram 2500 often come equipped with H-range tires from the factory.

If your vehicle's door jamb placard specifies Load Range E, F, or G, you should not automatically upgrade to H. Using a heavier load range than specified can mask weight problems and put stress on your suspension and brakes. Always match the load range your manufacturer recommends.

Load range and tire pressure work together

Load range capacity only applies when the tire is inflated to its rated pressure. The rated pressure is also printed on the tire sidewall, usually expressed in PSI (pounds per square inch). A Load Range H tire inflated to only 50 PSI cannot safely carry the full 1,500-pound load — it can carry less.

Underinflation is common and dangerous. A tire that's 10 PSI below its rated pressure can overheat, wear unevenly, and fail suddenly. Check your tire pressure monthly with a reliable gauge, and inflate to the pressure listed on your vehicle's door jamb placard, not the maximum pressure on the tire sidewall.

When to replace tires with the same load range

When your tires wear out, you should replace them with tires that meet or exceed your vehicle manufacturer's specifications. If your vehicle came with Load Range H, you can safely use Load Range H replacements. You can also use a higher load range (if one exists for your tire size) without harm, though it's usually unnecessary and more expensive.

Using a lower load range than specified — for example, replacing H tires with E tires — is not safe. The tire may fail under normal driving conditions, especially if your vehicle regularly carries heavy loads or tows. Always check your door jamb placard before ordering replacement tires.

Frequently Asked Questions

Is Load Range H the highest rating?

No. Load Range H is common for heavy trucks, but ratings continue beyond H. Load Range J, L, and M exist for specialized commercial and industrial tires. For most consumer vehicles, H is at the upper end of what you'll encounter.

Can I use Load Range H tires on a vehicle that came with Load Range E?

Technically yes, but it's not necessary and costs more. Your vehicle's suspension and brakes are designed for E-range tires. Using a heavier range won't improve performance or safety if your vehicle isn't actually carrying that much weight. Stick with what the manufacturer specifies.

What happens if I use tires with a lower load range than my vehicle needs?

The tire can overheat, wear prematurely, and fail suddenly under load. This is especially risky if you tow or carry heavy cargo. Always match or exceed your manufacturer's load range requirement.

Does load range affect ride quality or fuel economy?

Load range itself doesn't directly affect these factors — the tire's construction, tread design, and inflation pressure do. A Load Range H tire can ride smoothly or harshly depending on its overall design. Check reviews and specifications for the specific tire model you're considering.

Where do I find my vehicle's required load range?

Check the tire placard on the inside of your driver's door jamb, or look in your owner's manual under "tire specifications" or "tire placard." The placard shows the correct tire size, load range, and inflation pressure for your vehicle.
