I’m going to replace my front tires next week, one finally shed a steel belt. From rereading this post, it sounds like my best (cheapest) option for getting the TPMS working again is to have Discount Tire install the Schrader Universal sensor #33700, assuming that they have them. I have one year old sensors in the back tires with sensors that have never worked. Assuming that they are universal, should they be able to reset them all? Do I need them to get their codes first? Why does this have to be such a pain? 😄🤪
