  • I do have some information for you that will be helpful, but as far as reprogramming your 2024 BMW X5, you will probably get the same answer from any installer that you contact.

  • What Does GTW and TW Mean and What is Weight Distribution, 2008 BMW X5
  • I can certainly help you out. The TW is the tongue weight. This is the weight of the trailer at the coupler that attaches to the ball mount on the trailer hitch. It should be 10 to 15 percent of the GTW or gross trailer weight. The gross trailer weight is the total weight of the trailer. Weight distribution is a system that installs on the trailer frame and the trailer couples to a special shank on the trailer hitch. The spring bars that come with a weight distribution system take some...
