What is the load range E weight capacity? Is there any relationship between it and tire load index capacity? Let’s figure it out in this guide.
When looking at the sidewall of a tire, you can see different numbers, which contain important details about your tire. For example, the alphanumeric code includes an entire description of the tire, helping you determine if the tire is right for your vehicle or not.
There are different definitions when it comes to this, including tire load index capacity and load range. For instance, you might see E (Ply Rating) on a light truck and SUV tire. But what is the load range E weight capacity? This guide will help you understand the actual meaning of the load range E and other numbers on the tire,
Tire Load Index Capacity
Generally speaking, the tire load rating indicates how much weight the tire can carry. The major factors deciding the load-carrying capacity of all the tires mixed are the product of the number of tires and load capacity of a single tire. For example, the rating of 100 denotes that it has a load capacity of 1764 pounds. To get the maximum load-carrying capacity of your vehicle, simply multiply that by four tires, and here is 1764 x 4 = 7056 pounds.
Below is the detailed chart of load carrying capacity index ratings for your reference.
|Load-Carrying Capacity Index Ratings|
|Load Index||Load (lbs)||Load Index||Load (lbs)||Load Index||Load (lbs)|
To determine the right tire load index capacity, you need to consider the weight of your vehicle, including passengers and any cargo you might be carrying. Follow the guidelines provided by your tire manufacturer and make sure to never exceed the maximum weight capacity of your tires.

What is the Load Range?
If you have ever heard of PLY Rating, then load range is simply the older measurement of it. This term relates to the construction of the tire, which is made of rubber and cord layers known as plies. In the past, the tire had a bigger laid carrying capacity when there were more tires. As such, a lot of manufacturers would calculate a tire’s plies and use this figure to represent carrying capacity.
Having said that, the modern construct of tires is made with fewer plies without giving up the carrying capacity. Hence, the load range now simply indicates the tire strength and the allowable PSI. For example, a B load range denotes that a tire corresponds to a 4-ply construction tire. But in fact, this tire is not made with 4 plies. Instead, it is built with one or two plies of comparable strength.
You can look at the chart below to know more about the load range.
|LT-Metric, LT-Flotation, and LT-Numeric Light Truck Tires|
|Load Range||Ply Rating||Abbreviated||Maximum Load Pressure|
|B||4||B||35 psi (240 kPa)*|
|C||6||C||50 psi (350 kPa)*|
|D||8||D||65 psi (450 kPa)*|
|E||10||E||80 psi (550 kPa)*|
|F||12||F||95 psi (650 kPa)*|
|*Selected large LT sizes are designed with reduced maximum load pressures|
What Does the E Stand for on Tire Ratings?
In more detail, as shown in the chart above, the load range is distinguished by a letter of the alphabet, typically from B to F. These letters denote the load pressure and ply rating. When you see the letter E on the tire, it means that your tire has a ply rating of 10, and the maximum load pressure is 80 psi (550 kPa).
You will find this letter E in the middle of almost all tire service descriptions. Both sides of this letter will have spaces on them. Since it represents the load range of the tire, it is important for you to check your vehicle’s instructions to decide the proper load range. Besides, E indicates one of the highest load ranges available on the market. Therefore, if you are going to carry heavy loads with your truck, you might want to get this highly rated tire.
For today’s fleet managers, it is really crucial to have a comprehensive understanding of everything related to your vehicle’s tires, typically truck tires. Generally speaking, the load rating of a tire directly affects the carrying capacity of a vehicle. In addition, the load ratings impact both truck tires and passenger tires.
Another key thing to keep in mind is the load range, which is recognized by a letter of the alphabet. These letters are usually common from B to F that denote maximum load pressure and ply rating. The load range E weight capacity is 80 psi (550 kPa).
