The air holes that go in the tires are tiny. I put a ratchet strap around the circumference of the tire to bring the beads closer to the rim. Still does not work. I'm going to borrow a neighbor's air tank, which is used to add air to truck tires to put them on the rim. They are cheaper than OEM but could be better designed. I won't know if they will be able to communicate with the car until at least two are installed as two of mine have cracked and are leaking just because the manufacturer designed them to fail so they are more bucks to the consumer can earn.
