Hi!! Just before returning home in my 2-week-old MYP from a weekend out of town, I learned about a new warning sign on the touch screen. It says, "Dude!! Y'all got a flat tire!!" Of course, there is also the tire pressure "tab" on the screen which very accurately shows each tires current pressure. In any case, I used the tire "repair" kit to inflate the tires, and it worked perfectly. I did try to pump sealant into the tire. However, whenever the dial was on the sealant setting, the pump didn't work. I had the sealant hose connected to the tire. I could not figure out why the pump would not operate when on the sealant mode, having followed the instructions in the user guide to the letter. All worked out well, and even without the sealant setting functioning, I was darned glad that this tire repair kit came with the MYP. The MYP tires do have the sound decreasing foam in them, so even if the pump worked, the sealant probably would not have worked given what others have said about the foamed tires.
