Load Range SL vs. E: What’s The Best For Worry-Free Riding?

You might come across two terms when searching for brand-new tires: load range & load index. How does tire ply rating work? The load capacity of passenger and commercial tires can be divided into two categories: Standard Load (SL) and E.

In addition to that, there is the question between “Load Range SL Vs E: What does each mean? How do they provide information regarding the tire?

Let’s dive into each rating to see how both simple letters and these numbers help keep you safe when you’re driving on the highway.

Load Range SL Vs E: Overall Analysis

Whether at home or while working outside, we constantly search for comfort. The choice of tires can be divided into two types depending on the load capacity for passengers. In short, these tires are classified as SL and E.

“Load Range” Or “Ply Rating”

Load ranges are determined by a measure called a ply rating and indicates how much weight a tire can support. Treads are made up of rubber, and cord layers known as plies.

There are several plies on a tire indicating how large weight it is capable of carrying, as more plies means a load capacity is higher.

Ply ratings have been replaced by load ranges since tires consist of fewer and stronger plies. A tire’s load range is defined by its toughness & maximum pressure allowed and is indicated by the letter on its sidewall. More load-rated tires are capable of carrying heavier loads.

Standard Load “SL” Tires

It is called an SL or Standard Load tire if its load index indicates that its load capacity is essential for its tire size. The maximum load pressure for standard load tires is 35 psi.

Despite the load index on their sidewalls, they can support the withstand and the weight pressure. Internally, they are not reinforced.

Tires with normal load ratings are made mostly for cars that are used on a daily basis. It’s common for these tires to have either SL or no sidewall markings at all since they’re the most common passenger tires.

Load Range “E” Tires

The “E” symbol indicates a very high load range. If you operate a truck carrying heavy loads, you may need a tire rated this high. Unless you often haul or tow heavy loads, load range E tires aren’t really needed by most people.

They’re heavier, less fuel efficient, more difficult to ride, and they’re more expensive as well. Anything more than what a half-ton is rated for would probably be overrated with load range E tires.


The SL is mainly used by passenger vehicles used in everyday driving, so they aren’t usually able to carry heavy loads. The majority of passenger tires on the market currently lack any SL markings or do not have any at all.

On the other hand, E tires are designed for heavy duty and challenging applications. E tires are capable of carrying a much greater load when compared to SL tires. Their reinforced inner structures make them able to do so.

Life Expectancy

In addition to a weaker frame and structure, SL tires do not have reinforcements in their internal walls, so they are easily damaged. This is especially true if you have no concern for the condition of the street you are driving on.

Choosing the right streets and roads will ensure they last. Passing through potholes, mud, and murky water all the time will not make them last for long.

Due to the increased weight of the E tire, mileage is affected negatively. However, a truck isn’t truly an economy vehicle. Generally, when both tires are inflated to the correct pressure, E rated tires wear out faster than D rated tires. Heavier and thicker rubber holds heat for longer and heats up more quickly. Compared with SL tires, E tires are always better.

Driving Capabilities

The SL tire was designed for our everyday commute to and from work and the grocery store. For a short journey with fewer distances in between on our city’s streets, SL tires must be the optimal solution. As long as you know its limitations, you should not expect too much from it, or you might be disappointed.

Load range E tires are not necessary for most people unless they regularly move and tow heavy loads. Load range E tires are probably too heavy for a half-ton truck that has an EPA rating of 5 tons. “The new F-load range of tires offer truck owners best-in-class tire performance & style.

Load Range SL Vs E: What To Choose?

Are you thinking of getting updated tires soon? Load Range SL Vs E: which one is better? To be honest, you won’t be too concerned about which is the most ideal. Before buying one tire, you should consider the kind of vehicle you have.

As a daily driver, you should consider the SL model. Nevertheless, if you intend to carry large loads or if your vehicle has the capability of high speeds, the E tires may be a better option.


Is a higher load rating better?

Definitely not. A higher load rating will only allow you to carry heavier loads. Keep your tires at their recommended inflation pressure for a smoother ride on rough roads.

Can I tow with SL tires?

Of course. If you tow within the manufacturer’s limitations, you should have no problems towing.

Are E rated tires 10-ply?

A load rating or a ply rating is used to measure a load’s capacity. The Load Range “E” tire is interchangeable with a 10 ply tire.

Is Load Range D or E better?

Load range D has a capacity of 1,220 lbs at 65 psi, whereas load range E has a capacity of 1,520 lbs at 80 psi. Basically, the only difference between the two is the weight capacity.

Sum Up

Load Range SL Vs E: what should you use? According to tire experts, different tire properties are classified based on how well a tire can carry weight and hold air pressure. Load range allows a tire to carry a certain amount of weight.

On your tire’s sidewall, there is a letter indicating its size. Tires are rated from E to H depending on their load range. The loading range for your vehicle can be determined by looking at the manual.
