Questions for those who have winter tires on a separate set of wheels... do you have TPMS sensors or just rubber valve stems? Is OEM the only choice for sensors? Best choice? What about programming them? Is the system going to do it by itself with sort of an automatic relearn or is a special tool required? If you're using valve stems, is TR414 the ideal size/standard for OEM steelies from Mazda3 or Mazda6?
Thanks in advance!
