How long do TPMS sensors last? I've got a set on my winter wheels / tires going on 7 years old. Tires are only used ~5 months out of the year. I assume these have a battery of some type with finite life. I need new winter tires this year. Is it a good idea to replace the TPMS sensors while the tires are off, or can they go a lot longer than 7 years?
