2018 Toyota Tundra Payload Capacity

Firstly, let’s define what we mean by “payload capacity.”

Payload capacity is the total weight that a vehicle can safely carry, including passengers, cargo, and any accessories or modifications.

It’s important to note that payload capacity is not the same as towing capacity, which refers to the amount of weight that a vehicle can tow behind it.

The 2018 Toyota Tundra has a respectable payload capacity, with the ability to carry up to 1,730 pounds.

However, it’s worth noting that this number can vary depending on the specific model and configuration of the truck.

Let’s take a closer look at the different options available for the 2018 Toyota Tundra and their respective payload capacities.

SR Trim

Starting with the SR model, the 2018 Toyota Tundra SR has a payload capacity between 1,490 lbs and 1,730 lbs. This varies based on the drive type, engine size, cab size, bed size, curb weight, and GVWR (gross vehicle weight rating).

For example, a 4×2 double cab standard bed with a 5.7L engine has a payload capacity of 1,730 lbs, while a 4×4 double cab long bed with the same engine has a slightly lower payload capacity of 1,600 lbs.

SR5 Trim

Moving on to the SR5 model, the 2018 Toyota Tundra SR5 has a payload capacity between 1,440 lbs and 1,730 lbs. Again, this varies based on the specific configuration of the truck.

DriveEngineCab SizeBed SizePayload Capacity (lbs)Curb Weight (lbs)GVWR (lbs)

For example, a 4×2 double cab standard bed with a 5.7L engine has a payload capacity of 1,730 lbs, while a 4×4 CrewMax short bed with the same engine has a slightly lower payload capacity of 1,560 lbs.

Limited Trim

The Limited model of the 2018 Toyota Tundra has a payload capacity between 1,520 lbs and 1,660 lbs. This is slightly lower than the SR and SR5 models, but still respectable for most hauling needs.

2018 Toyota Tundra Payload Capacity 1794 Edition Trim

It’s also worth noting that curb weight plays a role in determining a vehicle’s payload capacity.

Curb weight refers to the total weight of the vehicle without any passengers or cargo.

The higher the curb weight, the less payload capacity the vehicle will have.

For example, a 4×4 double cab standard bed with a 5.7L engine has a curb weight of 5,470 lbs, while a 4×4 double cab long bed with the same engine has a slightly higher curb weight of 5,670 lbs.

2018 Toyota Tundra 5th Wheel/Gooseneck Towing

If you’ve got a 2018 Toyota Tundra and you’re thinking of towing a travel trailer, you might be wondering if a 5th Wheel/Gooseneck hitch towing is good. The answer is YES.

The 2018 Toyota Tundra has a towing capacity that ranges between 6,400 – 10,200 pounds depending on the options.

To determine the maximum trailer weight, you need to find the Gross Combined Weight Rating (GCWR) which is the maximum allowed tow rating of the vehicle weight and the trailer weight combined.

Subtracting the Gross Vehicle Weight (GVW) of the truck from the GCWR will give you the maximum Gross Trailer Weight (GTW) that can be safely towed.

The information tag located inside the driver door jamb provides this information.

Overall, the towing capacity of the 2018 Toyota Tundra is dependent on several factors, including the options and the trailer weight.

It is important to determine the maximum GTW and to choose the appropriate 5th Wheel/Gooseneck and base rails for a safe and successful towing setup.

Maximum Tongue Load of Toyota Tundra

If you’re planning on towing a trailer with your Toyota Tundra, it’s important to know the maximum tongue load that your vehicle can handle.

The tongue load is the amount of weight/force that the trailer tongue exerts on the trailer hitch and it’s crucial to stay within the recommended limits to ensure safe and efficient towing.

So, what is the max tongue load of a Tundra? Well, according to Toyota, for all of their engines, a tongue weight of 11% should not be exceeded.

This means that if you have a max towing capacity of 10,200 lbs, your tongue weight should not exceed 1,122 lbs.

It’s also worth noting that you should not tow above 1000 lbs on any 2018 Tundra without a trailer with a braking system.

Additionally, if you plan on towing a trailer weighing over 5,000 lbs, you’ll need to use a weight-distributing hitch.

One method involves using a specialized scale that measures the weight directly from the hitch ball.

What is the 2018 Toyota Tundra Curb Weight and GVWR?

Before we dive into the specifics of the 2018 Toyota Tundra’s GVWR, let’s first define what it means.

The Gross Vehicle Weight Rating (GVWR) is the maximum weight that a vehicle is designed to carry including passengers, cargo, and fuel.

It includes the weight of the vehicle itself plus anything else that is loaded onto it.

2018 Toyota Tundra Curb Weight & GVWR Chart (Towing and Payload Capacity)

Exceeding the GVWR can be dangerous as it puts extra strain on the vehicle’s suspension, brakes, and other components.
