2018 Tesla Model X Towing Capacity & Payload Guide

The 2018 Tesla Model X can tow up to 5,000 pounds when equipped with 20-inch wheels and the factory towing package. As one of the premier fully electric SUVs on the market, the Model X combines instant torque with standard all-wheel drive, making it a surprisingly capable tow vehicle for boats, small travel trailers, and utility trailers. However, towing with an EV introduces unique considerations, particularly regarding range and wheel size limitations. Always verify your specific vehicle's ratings by checking the door-jamb sticker.

Quick answer

• Max Tow Capacity: 5,000 lbs (with 20-inch wheels); 3,500 lbs (with 22-inch wheels)
• Max Payload: 1,120 to 1,250 lbs (varies by battery size and seating configuration)
• GVWR (Gross Vehicle Weight Rating): 6,768 lbs – 6,878 lbs
• GCWR (Gross Combined Weight Rating): Up to 11,800 lbs
• Curb Weight: 5,185 lbs – 5,531 lbs
• Hitch Class: Class III (2-inch receiver)
• Max Tongue Weight: 500 lbs (with 20-inch wheels); 350 lbs (with 22-inch wheels)

Note: The 2018 Tesla Model X towing capacities are rated in accordance with SAE J2807 standards.

Tow ratings by engine & trim

For the 2018 model year, the Model X is entirely electric, so "engine" refers to the battery pack and dual-motor configuration. All 2018 Model X vehicles feature an all-wheel-drive (AWD) drivetrain. The most critical factor for towing capacity on the Model X is the factory wheel size.

Disclaimer: Payload capacities vary significantly based on whether the vehicle has the 5, 6, or 7-seat interior configuration. Always check your tire and loading information placard.

Tow package contents

The factory Tow Package was standard on most 2018 Model X builds. Because it is an electric vehicle, it does not feature a traditional transmission cooler. Instead, the package and vehicle software include:

• High-strength steel tow bar
• Class III 2-inch hitch receiver
• 7-pin trailer wiring harness connector
• Trailer Mode software: When activated, this mode automatically disables Autosteer and Traffic-Aware Cruise Control, increases following distance, adjusts the Smart Air Suspension for leveling, and engages Trailer Sway Control.
• Integrated electronic brake controller compatibility: While it doesn't have a physical slider switch on the dash like heavy-duty trucks, the Model X features a pigtail harness connection under the dashboard to easily wire an aftermarket proportional brake controller (such as a Tekonsha).

5th-wheel & gooseneck

Because the 2018 Tesla Model X is a passenger SUV and not a heavy-duty pickup truck, it is entirely incompatible with 5th-wheel or gooseneck towing hitches. All towing must be done using the traditional rear-mounted bumper hitch.

Weight distribution & WDH requirements

Tesla strictly prohibits the use of Weight Distribution Hitches (WDH) on the Model X. The vehicle's unibody structure and standard Smart Air Suspension are not designed to handle the torsional stresses applied by weight-distributing equipment. Using a WDH can cause severe structural damage to the hitch mount or the vehicle's frame. To maintain stability, ensure your trailer is loaded properly with 10% to 15% of the total trailer weight on the tongue (not exceeding the 500 lb limit) and rely on the vehicle's automatic air suspension to keep the SUV level.

Real-world towing tips for this vehicle

• Range Anxiety is Real: Expect your driving range to drop by 40% to 60% when towing a heavy or non-aerodynamic trailer. A travel trailer acts like a parachute, drastically increasing aerodynamic drag.
• Supercharging Logistics: Most Tesla Superchargers require you to back in. When towing, this means you will likely have to unhitch your trailer, park it, charge the car, and then re-hitch. Plan your stops accordingly.
• Keep it Aerodynamic: If you have the choice, tow teardrop trailers, pop-up campers, or low-profile utility trailers to maximize your battery range.
• Activate Trailer Mode: Ensure "Trailer Mode" is engaged in the vehicle's UI to activate trailer sway control and optimize the regenerative braking and air suspension systems for towing.

Common towing-related issues

• Tire Wear: The Model X is already a heavy vehicle. Adding 5,000 lbs of trailer weight accelerates wear on the rear tires, especially considering the instant torque of the electric motors.
• Air Suspension Stress: The Smart Air Suspension works overtime to keep the vehicle level under heavy tongue loads. If a leak develops in the air struts, the vehicle will sag severely in the rear, rendering it unsafe to tow.
• Brake Controller Wiring: Owners frequently report difficulty locating the brake controller pigtail connector under the driver's side footwell. It may require a specific harness adapter from Tesla or an aftermarket EV accessory supplier.
