I'm getting ready to pull the trigger on a set of winter wheels/tires for my 2015 ST. The only issue, is I can't find a definitive answer on what I specifically need in regards for the TPMS sensor re-learning procedure. Paying someone else to do this is out of the question, I'd rather just buy what I need to do it myself. I was looking at some fairly nice Autel tools, but they are only supported up to the 2014 model (according to the latest documentation). I've read through some various threads on this site, it appears the 2015+ vehicle procedure is different from earlier years.
