The service write was very dismissive, as if to say "What would a tire shop know about a TPMS system? Only we here at Nissan can tell you what's wrong with your car."

When he said $250, I thought he might mean to diagnose and replace any of the sensors that needed replacing, whether it was 1 or 4.. When I had him clarify, and he said "per wheel", I would have spit my drink on him, had I been drinking anything. He even dismissed my inquiry about how long the internal batteries typically last on the sensors. I swear at one point he was about to try and tell me they don't have batteries, and stopped himself and said "They don't lose power, they just go bad." Nice enough guy to talk with, just definitely turned me off of ever bringing my car there for service.

I guess I'm gonna live with it until the next time I melt my tires off. I should get almost 2 more years out of all 4 tires, and have them wear out together this time. At that point, I might have enough saved to explore a wheel upgrade along with new rubber. I'll consider just getting 4 new sensors installed, if the wheels allow for it, but I'll probably just forgo paying $240 for a dummy safety system. I mean, it won't warn you unless you're really far off.. I don't want to get in a bad habit of thinking everything's great even though I could be running at 26 psi and destroying my shoulders. Manual inspection is hard to replace.

The copter flies over behind your instrument panel and lands on a tiny pressure plate that toggles your TPMS warning light to turn on. Check the FSM.

Our vendor Infiniti dealership wanted $420= for the set with our discount shipped but then I'd still have to pay the install fee...you figure it out! The difference is almost enough to by me a new rear bumper, less paint! Gary
