    Does anyone have any insight on the tongue weight limit on the hitch?

    I ordered the accessory hitch, not the towing package. The Tesla owners manual says the limit is 120lbs, but the hitch itself, the 2 inch Bosal, says 500 lbs with <22inch wheels, and 350 lbs with 22 inch wheels.

    This 350 lbs or 500 lbs figures seem a lot more consistent with other vehicles, and as a % of towing capacity. For example, our family's other vehicle, a MB GL350, has a 600 lbs weight limit for a 7500 lbs max trailer load. 120 lbs is not a lot - that's a rack and two mountain bikes, in a vehicle with 7 seats.

    Also, what does the size of the wheels have to do with it?

    Thanks

    When towing heavy trailers, the 22" tires are more prone to heat buildup and impact damage as compared to the 20" tires. As a result, Tesla decided to limit the trailer weight when using the 22" tires.

    Thank you. So that explains the difference between the 350 and 500. What about the difference between 350 and 120?

    You'll need to ask Tesla since you didn't actually get the accessory hitch you ordered.
