3,500 lb Towing Capacity on 22" Wheels For Model X (via ScottF)
The Tesla Model X is rated to tow up to 5,000 pounds, provided that it's optioned properly.
To tow 5,000 pounds, the Model X requires the $750 Tow Package and must be fitted with 20-inch wheels, not the optional 22-inch wheels.
If you opt for 22-inch wheels, the tow rating of the Model X falls sharply to 3,500 pounds.
Tesla began notifying those with configured Model X orders by sending emails like this:
Towing Email Model X
Essentially, if you're looking to tow at max rating in a Model X, then opt for the smaller wheels. If 3,500 pounds is acceptable, then you can go for the flashy 22-inch wheels.
