Load Range E Trailer Tires

What Is Load Range G

Weight Comparison: Goodyear Endurance vs. Dynatrail ST tires

The load range for a G rated tirerefers to how many pounds a G rated tire can carry. For Michelin, Goodyear and Firestone, their G rated tires can carry a maximum of 6175 pounds each.

That amount of weight also needs those tires to have 110 psi. Anything less that that psi and anything more than that load range, you can expect to ruin your tires. You also need to be aware that it is not the rubber of the tire that is actually carrying the weight.

It is the air inside the tires that shoulder the burden and the tire just helps keep the air in place. There is also another factor you should know about before assuming that all letter rated tires are the same in their individual classes.

Different tire manufacturers do not make all tires the same. For example, Firestone and Goodyear have the H rated tire capable of holding about 6610 pounds at 120 psi. Yet, Michelin has their H rated tire holding up to 7160 pounds at 120 psi.

So do not assume that all G rated tires will have the same performance as each other. Read the different tables from the different tire manufacturers to make sure you know what load and psi ratings you need to meet.

The Advantages Of A G Rated Tire

  • 1. It carries more weight than lesser rated tires
  • 2. Has a wider margin than lesser rated tires
  • 3. They can handle greater speeds
  • 4. They are safer to usein some cases
  • 5. You get better fuel mileagein some cases

The meaning of P, LT and ST

When it comes to tires, there are a number of letters, numbers and special ratings filling the conversation. It is vital to get to know what these letters and numbers mean.

Here are the 3 most common letters combinations you will run into when checking for RV and other smaller vehicle tires:

  • P + Passenger vehicles and they have the most tire designations
  • LT + Light truck usually a pick up that is rated as a 1/2 or 3/4 ton
  • ST+ Special trailer andthese tires are rated for trailers only and have less tread depth than other tires.

What Is The Difference Between Load Range E And F Trailer Tires In The Same Size


What is difference in load ranges E or F? I have trailer with 235/85/16 inch. Have had Load Boss tires. Heavy loads, hot weather, fast speeds. Custom trailer. 3500# double axles.

asked by: Lori

Expert Reply:

The difference between a load range E and load range F tire of the same size, 235/85-16, is the weight capacity and pressure. The Karrier Radial Tire, Load Range E,, has a capacity of 3,640 pounds at 95 psi.The Load Range F Tire,, has a capacity of 3,960 pounds at 95 psi.Trailer tires should always be inflated to the maximum psi rating indicated on the tire. If a tire is under inflated, it will cause the side wall to build up more heat faster and cause the tire to fail. Trailer tires have a thicker side wall so that they can handle more vertical load, passenger vehicle tires do not have as thick of a side wall so they should not be used on trailers.I have included a link to our FAQ article on trailer tires for you to view.

What To Look For When Buying A Trailer Tire

Like any other product, there some research you need to do before buying a trailer tire. In fact, there are many different factors you must consider and think about when trying to decide which trailer tire will fit your particular needs.

In this section, well go over these factors and give you all the information you need to make an informed decision about the right trailer tires for you.

Load Range/Load Rating and Max Weight

Every tire ever manufactured has a load range. Just like with most tires, the load range is located on a trailer tires sidewall. This designation will tell you the maximum load each tire can haul.

For most trailer tires, the load range is going to either be B, C, D, or E. Lets say you have a single-axle trailer and your tires load range is classified as load range C which can carry up to 1820 pounds this means you can tow up to 3640 pounds.

Of course, this maximum towing capacity includes the weight of the trailer itself. However, thats still an impressive number. On the other hand, if you have a double-axle trailer, you must subtract 12% from the load rating. So, instead of 3640 pounds, the maximum of a load range C double-axle trailer becomes about 3204 pounds.

In the end, you must understand the exact weight you need your trailer to carry and correlate it with your trailer tires load range. In doing so, you ensure safety and peak performance.

What Is The Difference Between Load Range C And D

The main difference in these two tire ratings is the same as the E and the G difference. The D is going to be stronger than the C. Plus, it will carry more weight than the C load range tire.

The tricky thing about these letter rated tires is that there will be times where both types of tires will fit on the same wheel. For example, the ST175/80D13 is the same size as the C # AM1ST76 and will fit on the same wheel.

Yet the D rated tire can hold up to 1,610 pounds of weight at 65 psi. The C class tire can only hold 1,360 pounds at 50 psi. Thus if you use a C rated tire, expect your load range to fall dramatically.

One key about using these tires is to check the axle capacity before you buy any C or D tire. Your axle will have some say in which rated tire you can use.

Radial Tires Vs Bias Tires

Radial ply tires are designed for trailers that are towed on the highway. The cords on a radial tire are positioned at a 90-degree angle to the direction of travel so that they lay across the width of the tire from wheel lip to wheel lip. This construction prevents the cords from rubbing against one another when the tire flexes, unlike the cords on a bias ply tire. As a result, radial tires have less rolling resistance and heat buildup, which leads to a longer tread life and improved steering at higher speeds.

  • 2. They should have a smoother ride
  • 3. They carry more weight than the B, C and D rated tires

  • 5. You get more tread wear than the lesser rated tires

Best For Snow: Bfgoodrich All

Best Tires For Hauling || Load Ratings

There are plenty of good winter tires out there, but we believe the BFGoodrich All-Terrain T/A KO2 is the best one if youre looking for absolute performance on snow.

Come mud or snow, its an excellent performer and hence why offroad and truck enthusiasts love them. However, as you can probably tell, the deep and aggressive tread pattern means that its not the best for road use. Some customers have complained that its excessively loud while on the road.

Nevertheless, these are excellent for snow and thats what were looking for here. The only downside is that its not studdable should you need help in icy conditions. For that, take a look at the Falken Wildpeak AT3W or the Goodyear Wrangler DuraTrac.

The BFGoodrich comes with a 50,000-mile treadwear warranty, and starts at a reasonable $219, although larger sizes are anywhere between $300 $430 per tire.

How About The Load Rating In Passenger Tires

Why Is This Important

Its important because when you carry heavy loads, youll want to increase the tire pressure. This is because heavy loads will push down on the tires, increasing their contact patch with the road. While this means more grip, it can lower fuel efficiency.

Additionally, your tires may lose pressure more quickly due to the heavier load. So, by increasing the tire pressure, youll prevent a flat tire whilst youre driving, especially on longer drives.

Many truck owners also say that having a higher tire pressure will prevent the trailer from snaking, making it overall safer to drive. This is because higher tire pressure stiffens the tire wall, making it more rigid and stable.

Since not all tires are built equal, its important to consider your tire load rating to see how much PSI you can inflate it by. If you inflate to above the rating, you risk having a tire blowout since the tires are not strong enough to handle it.

Replacement Trailer Tires With Load Range E

We do sell ST205/75R14 tires, such as, however the maximum load range is only high as D.The closest tires we have to the ST205/75R14 with an E load range that you’re looking for are that are ST225/75R15 and have a load range E. They’ll be almost an inch wider and about 2 inches larger in diameter. So, if you decide to go larger, you’ll want to make sure you have at least 4-1/2 inches of clearance between the tread and the underside of the trailer’s fenders, as well as at least 2 inches from the tire’s side wall and the inside of your trailer’s wheel wells. This tire comes mounted on a rim that has a 6 on 5-1/2 inch bolt pattern. If this isn’t your bolt pattern I’ve attached a link to other tires of the same size that are an E load range.

Libra All Steel Trailer Tires

Most trailer tires on the market have an eight or ten-ply rating, which is sufficient for hauling moderate loads. However, trailer drivers who want more heavy-duty tires for their rigs should consider the Libra Gremax All Steel Trailer Tires 225/75R15. These tires might look like any other rubber, but their construction is top-notch.

As the name implies, these tires feature heavy-duty steel belts in a radial design. There is no doubt about its performance on the road, its exceptional heat dissipation capabilities, and the smooth ride it offers. After all, thats what radial tires bring to the fore.

However, what separates this tire from other brands is its 14 ply construction. For example, the Hykolity is only 10-ply, while the FREE COUNTRY only has eight plies.

I was surprised to learn about this configuration because the highest ply rating I knew was 12. I could only imagine the load these tires can potentially carry, besting other tire brands.

And I was right. Each tire can accommodate 3,525 pounds or a combined four-wheel weight capacity of 14,100 pounds. Its weight rating should make hauling a large livestock trailer or a toy hauler a cinch. An oversized camper will be a breeze to pull with these tires providing the rolling action.

Although these tires have an M speed rating equivalent to a maximum of 81 MPH, I do not want to push it. Regardless, it is always comforting to learn that these tires will not burst when I drive my rig faster than usual.
