I have a 2016 380t. The tires were worn out so I tried them out before spending another $400 on new gear. Find a YouTube video that shows you how to replace them. It's very useful. The wheels fit my car perfectly; It was difficult to remove some parts from the wheel mechanism. You need to disconnect the cable that makes the charging connection to the charging station. After we reconnected and reassembled Braava, it didn't hold a charge and the charging station didn't recognize it. I found I could plug the charging cable straight into the bottom of the car, so we plugged it in overnight to give the battery a good charge. Now it works fine except it still won't connect to the charger so I just plug it straight into the charge port on the car. Cleans well, tires no longer squeak! In addition, the tires are already glued to the wheels for you. They come with an extra set of tires and can be glued onto your existing wheels if you want to try before changing wheels.
