A tire's load pressure durability and tire ply rating go hand in hand. When looking for new tires, often getting the higher load capacity tire might seem like a good idea. But, is that really the case?
Often purchasing the old reliable load range is better. This is where Load Range E tires come into play. They are popular, they offer good performance, and the load range E weight capacity is nothing to sneeze at.
E-rated tires are perfect for wheels handling heavy loads daily. They ensure the durability, controllability, and performance of the vehicle.
What Does Load Range Mean?
The load-carrying capacity of light trucks is categorized by their load range. The load range letter of each tire determines the maximum load pressure a single tire can handle. Depending on this letter, the tires have more or less durable constructions.
Tires with higher load ranges are able to carry heavy loads, as the tire's plies maintain their ideal tire shape. As the tires do not deform, they are able to also offer better traction, even with LT flotation models. Furthermore, the load range letter will also determine the maximum allowable PSI levels of the specific tire.
Typically light truck, trailer, and commercial truck tires require the highest load ranges available on the tire market. But, what is the max load capacity of these tires? Let's take a look.
Tire Load Rating Chart
On this load range chart, you will see all the important information regarding load range ratings.
Load Range vs Load Index (Load Rating)
Now, the question arises: what is the difference between load range and load index capacity?
Simply speaking, the load index is used for P-metric sizes, while the load range is for trailer and LT tires. The difference is simply their ply structure and load-carrying capacity.
However, when looking at things closely, their maximum load capacity makes a huge difference between the tire type categories. This is due to it affecting the tires' performance, traction, fuel efficiency, tread life, etc.
The max load durability of P-metric sizes is measured in with load index. The tire load index capacity is represented with numbers, which show the load capacity of passenger cars and SUV tires.
Check out the Tire Load Index Chart below:
Additionally, they can also be separated into Standard Load and Extra Load tires - which are more reminiscent of load ranges. This determines the maximum pressure (load and driving) that SUV and passenger tires can handle safely. Even extra load tires are weaker than LT-metric sizes.
You can find the load index on the tire's sidewall before the speed rating. Together they form an alphanumeric code that represents the speed and load capacity of each tire. They will differ from tire to tire, depending on the tire size and performance.
What is Load Range E?
As the load range rating tells you the maximum load capacity of each tire, there will be certain tires that offer less or more plies in their construction. So, where do E-rated tires belong?
Load range E tires come with a 10-ply rating. This means that the construction of the tire offers equivalent strength to a 10-ply structure, but it does not necessarily feature 10 plies. As an example, the actual meaning of the E rating is that a single tire can handle 1,520 lbs at 80 PSI.
This means that all the tires with this rating will have the same maximum load carrying capacity thanks to the cord layers, plies, and internal structure. They are able to carry more load than a load range D or C tire, but less than a load range H size. This is the same for both radial and bias-ply tires.

How Many Ply is Load Range E?
Load range E is a 10-ply rated tire. However, this does not mean that load E tires feature a 10-ply construction. Usually, the tires have 1 or 2 plies, which are equivalent in their strength to 10 plies. This construction offers the load range E weight capacity, which is 1,520 lbs/tire.
Can Passenger Tires be Load Range E?
No, passenger tires cannot be load range E. Manufacturers build these tires with standard load or extra load ratings, but they are not equivalent to LT-metric load ratings.
In fact, most SUV and passenger tires all feature 4-ply ratings. Pay close attention to their sidewall, where you can see their load index and speed rating, as well as their standard load or extra load specifications. Still, keep in mind that the tire load index capacity is less than a load range E max load rating, as passenger tires with load index ratings are smaller.
The Difference Between E1 and E2 Load Range
Let's complicate things even more! Did you know that E1 and E2 load range ratings exist?
Generally speaking, both of these ratings offer the same maximum load and performance. However, the difference is between their sizes.
E1-rated tires have lower than 305mm footprint widths. They require 80 PSI to perform at the desired level and load capacity. This type of tire is perfect for on-road use, as its footprint optimizes its road gripping ability. Whether they are trailer tires or are used for towing, they will offer excellent driving safety for the vehicle.
On the other hand, E2-rated tires are tire sizes that feature 305mm and wider footprints. They run at lower PSI levels than E1 tires, as they need only 65 PSI to perform. This improves their flotation, which is important for off-road use.
You might have heard of flotation tires regarding agricultural equipment. These tires use less air pressure levels to offer the same performance and traction, without ruining the soil and field quality. E2-rated tires are similar, as they use LT-flotation to grip the surface and optimize their off-road traction.
Yet, even at lower PSI levels, load range E2 tires offer the same max load-carrying capacity.
How Much Weight Can a Load Range E Tire Carry?
Depending on the tire ratings, specific tires offer various maximum pressure durability. For example, a tire load range E rating means that the specific model and size can handle 1,520 lbs at 80 PSI. In other words, when the trailer or light truck tires hold the correct air pressure levels of 80 PSI, they can carry 1,520 lbs/tire.
Are Load Range E Tires the Most Popular Light Truck Tires?
When it comes to light truck tires, and even some trailer tires, models with the tire load rating E are among the most popular ones. There are good reasons for this!
The E ply rating offers the necessary maximum load pressure durability for LT tires. This optimizes vehicle performance, the tire load-carrying capacity, and versatile surface grip, all without hindering the tire's durability.
Combine with their wider range of speed rating options and tire sizes, E-rated tires offer all desired characteristics light truck owners are looking for. Just remember, it is important for all four tires to have the same load range for the vehicle to securely perform.
Frequently Asked Questions (FAQs)
Is Load Range E good?
Yes, Load Range E tires are good, as they provide the necessary load durability. They are able to typically carry 1,520 lbs at 80 PSI without issues. This makes them perfect for most light trucks, which require higher tire load range capacity.
What's Better: Load Range D or E?
Load range D and E tires have different weight capacities. For example, a load range D tire can handle 1,220 lbs at 65 PSI, while an E tires carry 1,520 lbs at 80 PSI. If looking at their load durability, load range E tires are better, but that is the only difference between them.
Are All 10 Ply Tires Load Range E?
Yes, all load range E tires are 10 ply. This is because load range is determined by the number of plies the tire's construction has. Therefore, load range E means that the tire sports a 10-ply structure, which corresponds with its load durability.
