Hi all, This is my first post. I ordered a Silver GT Premium for the wife a few weeks back(It's being built today12-16, as you read this), and I have a few TPMS questions: I am setting up a set of winter only tires and was wondering which of the mirad of sensors on ebay will work for this car? Will any of the 315mhz sensors work? Secondly, do I need to buy one those learning tools, or are the '15s self learning? Any help would be greatly appreciated!
