RVing is a great way to see the country. Some people live in their RVs full-time while others only use them occasionally. However, what most people don’t realize is that the tires shoulder most of the burden.
When comparing E-rated tires vs G-rated tires, it’s important to remember that the primary differences are based on the amount of weight they can carry and their longevity. In general, a G-rated tire will be stronger than an E-rated tire, able to carry more weight and have a longer lifespan.
What Are E Rated Tires?
The farther you descend into the alphabet, the more weight a tire can hold. So an E-rated tire will carry more weight than A-D, but less than any letter that comes after.
Unfortunately, an E-rated tire will barely work on a heavy RV or trailer.
In addition, load range E tires only have a 10-ply rating with an 80-psi maximum, meaning it can’t carry very much weight – not nearly enough for a class A motorhome, large fifth-wheel, or even a longer travel trailer.
E tires work well on smaller teardrop trailers and pop-ups.
The uses for E-rated tires are very specific. You already know now that you can’t use them on larger rigs, but you also shouldn’t use them on passenger vehicles.
While they’ll handle the weight just fine, they’re not designed to offer a smooth ride.
What Is A G Rated Tire?
Load range G tires are the second heaviest duty tire behind an H. They carry a 14-ply rating and have a 110-psi maximum, making them ideal for heavier RVs. In fact, most RV manufacturers require G-rated tires for their vehicles.
I can attest to their strength and longevity because I lived in a 45-foot toy hauler with my family for two years. It was already five years old when we bought it, and it still had the original tires.
We traveled thousands of miles every month, moving from location to location, without any problems. When we finally got the tires replaced, we opted for another set of G tires because they were so fantastic.
G-rated tires can carry more weight than E-rated tires, but they’re also significantly more expensive. Trust me, a set of 6 for our RV set us back about $1200, but it was definitely worth it.
You’ll find these tires on high-end RVs, luxury coaches, and some of the heaviest travel trailers. They provide a smoother ride and will last longer than any other type of tire.
Differences Between E And G Rated Tires
There are several differences between E and G tires, and these differences are significant. They have a big impact on how you can use them.
1. Weight capacity
The primary difference between E and G rated tires is their weight capacity. E-rated tires are designed for lighter vehicles while G-rated tires are meant for heavy-duty use.
The average amount of weight an E tire can hold is 3,500 pounds while a G tire can hold up to 6,250 pounds.
The second difference is longevity. E-rated tires will typically last for 30,000 miles while G-rated tires will last for 50,000 miles.
This is a significant difference and something you should keep in mind when making your decision.
3. Smoothness of ride
The third difference is the smoothness of the ride. E-rated tires are not designed for a smooth ride.
They’re designed for light-duty use only. G-rated tires, on the other hand, are designed for a smooth ride. This is one of the reasons they’re required by most RV manufacturers.
The fourth difference is cost. E-rated tires are less expensive than G-rated tires. This is because they’re not meant for heavy-duty use and don’t last as long.
If you’re looking for a cheap option, E-rated tires are the way to go.
But if you’re looking for a tire that will last longer and provide a smoother ride, G-rated tires are the way to go.
5. Designated uses
Because of weight ratings and smoothness of the ride, each type of tire is made for different use.
E-rated tires are perfect for utility trailers, pop-ups, and teardrop trailers.
Neither is meant for a personal vehicle.
Advantages of E Load Tires
E-load tires have a number of advantages that make them ideal for certain vehicles.
Here are some of the benefits of E-load tires:
- They’re less expensive than G-rated tires. There are several reasons why an E-rated tire is less expensive. With only a 10-ply rating, these tires don’t require the same amount of materials as G-rated tires, which have a 14-ply rating. E-rated tires also don’t require as much labor to build.
- They’re lighter than G-rated tires. Because the tires don’t weigh a lot, they put less pressure on your suspension and can improve your gas mileage. That means that your tow vehicle will get better gas mileage than if it were pulling a trailer equipped with heavier tires.
- They can carry more weight than tires with lower ratings. B, C, and D-rated tires can’t carry as much weight as an E-rated tire. That means that if your trailer is close to the weight limit for those tires, you’ll need to upgrade to an E-rated tire.
- They can handle off-road conditions better than lower-rated tires. If you take your trailer off-road, an E-rated tire is a good choice. They can handle rocks and other obstacles better than tires with lower ratings.
- The tread will wear slower than lesser-rated tires. E-rated tires have a thicker tread than lower-rated tires. That means they’ll last longer and won’t need to be replaced as often.
Advantages of G Rated Tires
There are a number of advantages of G-rated tires that make them ideal for certain vehicles.
Much like with E-rated tires, G-rated tires will have an advantage over lesser-rated tires, which includes the E rating.
- They meet the requirements of most RV manufacturers. If you have a fifth wheel, motorhome, or travel trailer, you’re going to need G-rated tires. That’s because they can handle the weight and provide a smooth ride.
- They’re designed for a smooth ride. One of the main advantages of G-rated tires is that they’re made for a smooth ride. If you want a tire that’s going to provide a comfortable ride, G-rated tires are the way to go.
- They have a longer lifespan than E-rated tires. G-rated tires are made to last. With a 50,000-mile lifespan, they’ll outlast E-rated tires by 20,000 miles.
- They can handle more weight than E-rated tires. G-rated tires have a 14-ply rating, which means they can handle more weight than E-rated tires. If you have a heavier trailer, you’re going to need G-rated tires.
- They have a higher speed rating than lesser-rated tires. If you want to tow your trailer at higher speeds, G-rated tires are a good choice. With a speed rating of 81 mph, they can handle the extra speed. It’s not recommended that you go that fast or exceed the posted speed limit, but they’re better equipped for areas where the speed limit is greater.
Both E-rated and G-rated tires have their advantages, from price to gas mileage and weight rating to lifespan. It’s important to choose the right tire for your vehicle and intended use.
If you’re not sure which tire is right for you, consult with a professional or the manufacturer of your vehicle.
