Safe towing starts with knowing your limits. Every part of the setup – vehicle, hitch, ball mount, ball and trailer – has a rating, and the lowest one is your limit.
Know your numbers
- Towing capacity – in your owner’s manual.
- Gross trailer weight (GTW) – the loaded trailer.
- Tongue weight – the downward force on the hitch, commonly around 10-15% of the trailer’s weight.
Hitch classes
Receiver hitches are grouped into classes by capacity and receiver size, from light-duty 1-1/4 in. receivers to 2 in. and larger for heavier loads. Choose a hitch rated for your vehicle and your trailer.
Ball mount and ball
- Match the ball diameter to the trailer coupler (common sizes: 1-7/8, 2 and 2-5/16 in.).
- Choose a drop or rise that keeps the trailer level when hitched.
- Use the correct hitch pin and clip, and torque the ball nut as specified.
Trailer wiring
Trailer lights need a connector that matches the trailer – 4-way flat for basic lights, 7-way for trailers with electric brakes. Vehicle-specific T-connectors plug into factory wiring without splicing. Test running lights, brake lights and turn signals before every trip.
Every trip
- Cross the safety chains under the tongue and attach them securely.
- Check trailer tire pressure and lug nuts.
- In California, vehicles towing trailers are limited to 55 mph and must use the right-hand lanes as posted.
