What Does SL Mean on a Tire?

The SL in the tire size means it is a standard load tire. The ply rating for an SL tire is 4. A classification of SL means it’s a standard load tire. Most passenger tires are standard load, but standard load tires can also be used on some light trucks and SUVs.

The maximum load capacity of an SL-rated tire is typically around 1874 lbs. per tire at 51 psi of air pressure. This article is all about this.

What does SL mean on a tire?

What Does Load Range SL Mean

SL tire ratings mean that the tires are designed for speed ratings of up to 112 miles per hour (MPH), and for load indexes of 100 or more. SL is an abbreviation for “Standard Load” and designates a type of tire that is recommended for passenger cars and light trucks.

The letters appear on the sidewall of the tire, abbreviating the tire’s service description, which indicates its load capacity, speed rating, and internal construction.

What is the load capacity of an SL tire?

Load Capacity Of An SL Tire

The load capacity of an SL tire depends on the tire size and its maximum PSI. For example, a P215/75R15 with an SL rating has a maximum load-carrying capacity of 1,820 pounds at 51 PSI. That’s the same as 910 pounds per tire. A tire with a higher load rating will have more load-carrying capacity than one with a lower rating.

What is the difference between LT and SL tires?

Difference Between LT And SL Tires

LT tires are designed for heavy-duty applications, such as hauling large quantities of cargo or towing trailers. They are also known as light truck tires and are typically manufactured by using stronger materials than passenger-vehicle tires.

There are several types of LT tires; some have a reinforced structure and more aggressive tread than a standard vehicle tire while others have special features.

What is the difference between XL and SL tires?

The Difference Between XL And SL Tires

Passenger vehicle tires have an SL rating, which stands for the standard load. These tires are rated to carry less weight than LT tires, but they have softer sidewalls, which gives them a more comfortable ride quality. Many passenger vehicles use XL tires, which stand for the extra load. These tires can safely carry more weight than SL-rated tires.

Can I tow with SL tires?

Tow With SL Tires-min

Yes, you can tow with tires rated SL. It’s not recommended, but it is okay to do so. The main reason why it is not recommended is that the speed rating is lower than LT tires. For example, many of the tires we offer are rated for speeds up to 106 mph.

How many plies is SL?

A load range of SL means the tire has a single-ply and can carry a load of up to 1874 lbs. at 65 psi. The PLY rating is a measure of the strength of the tire’s construction. Each ply is an additional layer of rubber-coated fabric in the tire casing that adds strength and durability to the tire. The higher the number, the stronger the tire.

Are higher ply tires more puncture resistant?

Tires More puncture rResistant

The answer to this question is yes, in a roundabout way. Higher ply tires have thicker, heavier sidewalls and treads, making them less likely to be penetrated by sharp objects. However, the air pressure inside the tire is just as important.

 A well-inflated tire is the most puncture-resistant tire you can buy. The downside to having a high ply count or the heavy tread is that it may hamper the performance of your vehicle.

Do load range F tires ride rough?

Load Range F Tires Ride Rough

This is also a yes and no answer. Load range F tires have thick sidewalls, which make them durable but also stiffer than other light truck tires with lower ply ratings. They can provide a rougher ride under normal driving conditions, but they’re designed specifically for hauling heavy loads and are most comfortable when they’re loaded down. E rated tires.


The road hazard protection plan will cover most repairs, including tire punctures from nails or other road debris. If a tire cannot be repaired, it can be replaced with a comparable new tire.

You can put a P (Passenger) rated tire on if you only use your truck for passenger car duty and not for towing or hauling heavy loads. Thank you very much for reading this article with patience.
