You need to buy new sensors from the dealer for the new wheels. You could also remove them from the stock wheels but that just means you will have to put them back in them if you plan on running them as winter wheels. I got mine for $41 each from the dealer. I know I could have gotten them cheaper but i wanted to get my wheels on ASAP. I meant to take a picture of the valve stems before mounting them but i got to excited to put the wheels on so i forgot.
