Tire Pressure Monitoring sensors - to replace or not to replace

Postby james t kirk » Fri May 04, 2018 10:20 am

I have a 2012 G37x purchased new by me in November 2011.

It's time for a new set of tires (I also employ winter tires.) The summer tires are OEM Goodyears and frankly they suck. They have always sucked, but not enough to replace them. But they are getting hard (actually, they are hard and have been hard for a while now. Which is a big part of the reason I say they suck) and close, but not at, the wear bars.

So I want to get a new set of Michelins.

Now, what I'm wondering is, "while I'm in there" does it make sense to replace the TPMS sensors? I say this because I had a 2005 G35x (man, I loved that car, the 2012, not so much) and I had to replace the TPMS sensors on that one after about 7 years (just before I bought the new one).

So I'm figuring that at some point in time in the near future, the existing sensors will die and need to be replaced. Which means pulling the tires off the rims (never desirable) and then rebalancing, etc. Added cost.

Do the TPMS sensors of a 2012 have a life span (like the ones on the 2005 did) or are these a completely different design and will last forever?

I'm pretty sure that they will die, but I'm just wondering if anyone has had their sensors on the same generation G37 need replacing?

mac , my 2 cents is you would get VERY similar life expectancy = 7+ years , and IF driving habits has ANYTHING to do with that - it's YOU ,your the same guy ,oughtta see similar results , and TPMS SHOULD only (i'm guessing) get BETTER lifespan cause Lith.?(Di-Lithium crystals Captain?) batteries are getting better. My apples to your oranges , I had 2008 van sold in 2016 TPMS good 8+ yrs , 2010 car TPMS going strong still today!
:crazy:Subjectively speaking I would take lightly a TPMS going out ,especially if it was a 4-way system & not "Illumination upon any" .Also sounds like, hard tires? ,you DO keep'em long. I have this yardstick though - IF 'n you make $$ 75k+ / yr CAPTAIN - maybe CHEAP NOT TO :lolling:

In general the older TPMS were usually good for 5-7 years and the newer ones are good for 7-10 due to better batteries. It comes down to cost and convenience. If you replace them all now you _should_ be good for 7+ years. If you don't then you will actually pay more (4 shop trips for work to be done vs. them simply replacing them all as part of the tire swap) over time.

My 2011 G37S sedan with just over 90K has the sensors still working well. If it was me I wouldn't worry about it til they stopped working.

The only issue I have with the "wouldn't worry about it" scenario is over the next few years he may have to make 4 separate trips to a tire place to get them replaced vs. simply replacing them at the same time.

Can always drive with the TPMS light on....I do and you get used to ignoring it. My G37 didn't have TPMS in the wheels at all for 8 years and the wheels I have on my Q50 have incompatible TPMS in them (and I'm too lazy to take the factory wheels to a tire place to have them swapped)

mac, telcoman ,that's a nice 4-way ,that's what I'm talkin' about. You can see the "individual " TPM if one goes bad , they ALL won't go at once -right , and still you got SOME confidence of being able to watch others!

Well, yeah. I assumed that was understood. But you're right that I should have added it. :)

I replaced all 4. There is no way in hell they would have lasted another 5 or 6 years.

It's cheaper to do it "while you're in there"

4 new Michelin Pilot tires replaced at the dealer.

Price was as good as any tire place and no issues or grief with TPMS sensors.
