I have a 2012 E350

How long do folks find the TPMS last before needing to be replaced?

KEY08

8 years, give or take

I had them on W211 lasting over 10 years and with high mileage.
Why the question? Are your TPM original?
If that so, replace them with next new tires.

2012 CLS(bought new), still have not replaced them Wheels and tires changed MANY times over this time period. I did buy some from a member here as back ups a few years ago when I was expecting mine would fail, so far....not used 'em yet.

10 years is a good run, it really depends on how much their used, I use mine maybe four times a year, they are original in my '12 and '13

Zavato

Yes, original; my tires are a 1.5 yrs old- next tire change is a fine idea- thanks-

I had heard that when you replace the tires those will have to replaced as well, Well, it must be myth

10 years is nominal battery life per most manuals.

our milage may vary.

What sucks is you go 11 years and still working
get new tires
They work for a year and then battery dies...

then you have to get tires remounted to replace batteries.

So think about it when you are around 10 years and are getting new tires

Curious though, but do our tires really last that long though?

kajtek1

it all boils to how much you are paying for the things.
For me, I can buy new OE sensor for $15, if the sensor dies, it is going to cost me at least $25 labor to replace it and rebalance the wheel, not to mention additional hassle.
So $15 preemptive cost looks good.

2014 here. I had the rear right sensor die just after I bought the car, last year.

Didn't want to go through the hassle of ordering a new sensor every time another one stopped working, so I went ahead and replaced all 4 with OE Schrader sensors. No programming required.

I stated TPMS battery last ten years..
nothing about tires
but over 10 years you may be just buying your 3rd or 4th set of tires..
We all drive different Miles per year so who knows

What I know is, My tpms are about 7 years old
Probably need tires in 2-3 years.
so next set of tires I will get new TPMS installed.

I have the same plan. I'm not installing new TPMS sensors unless I'm doing something with the tires, too. If that means a couple sensor batteries die beforehand, then Ill suffer through...

W205C43PFL

Sorry about that, thanks for the clarification, I was wondering if it was even a good idea to keep 10 year old tires even if they still have tread, after all, the rubber does have shelf life and probably not safe to keep them that long. I got curious and asked you the question because mainly I didn't know our tires actually last that long which I guess in reality they don't. Thanks for clearing up the confusion.

The spare tire in the trunk of my C-Class is at least 15-years old. I'm not buying a new tire to replace it.

With as little mileage as I am putting on my E-Class due to the pandemic, retirement and my age, I can see my tires lasting at least 10 years. I don't think tires can "dry-rot" when they are rolled occasionally. So I choose not to drink the Discount Tire cool aid, and am not losing any sleep over it.

Last week I watched an episode of "Collecting Cars" in which Wayne Carini reinstalled 40-year old OEM tires on a collector car for a prestigious car show and it's associated auction.

hyperion667

I have the wheels, and the OEM tires for my CLS out in the barn......no way in hell I'd ride on those 10 year old tires. I do think there is some validity to dry rot. But as you said.....having them out once in a while does help.
I'm guessing because of this thread my TPM's will fail any day now lol.

W205C43PFL

Ya the rolling does help for sure, and as for the spare, definitely recommend periodically checking on it, after all it is a convenience feature when or if there is a flat it comes in handy so you want to make sure that it is functional when you do need it.

Ya I thought of "better safe than sorry" which is why there is such thing as preventative maintenance (just imo) I mean people can argue modern synthetic motor oil can last way beyond the 10,000 miles interval that manufacturers suggest to have it changed, I am not saying there isn't a possibility of it lasting even 20,000 or 30,000 miles but why why risk it when it is cheap insurance for the motor? Manufacturers sometimes suggest sealed for life transmission fluid (which backfired for MB) or differential fluid but why risk it? (just my opinion though)

It's "dry rot," yes, but also the rubber hardens with age (outdoors in UV will fare much worse, but still will degrade inside a garage). Losing that tire compliance means all seems perfectly fine until a high-stress maneuver like an emergency swerve or nailing the brakes occurs. Those really old --read, hard-- tires will absolutely not grip as well as tires that are under 5 years old. With a spare tire that simply gets you off the road and back home, no biggie, then back in the ol' trunk. Saving money I understand. But compromising safety with tires I am rolling on is not where I am comfortable, personally. Just consider it

Compact spare tire is having much more rubber and reinforcement, so being shaded from UV, can last much longer than tires in use.
Semi truck tires can hold for 40 years, but old tire had 12 plays of fabric and sidewalls up to 3/4".
That said I always go extra way to keep my cars out of direct sun and I have been using 10 yo tires just fine. I also use 303 Protectant from time to time.
Michelin tires are prone to early haircracks, who should not be ignored on thin sidewalls.

I have a 2017 E300. I replaced the wheels/tires and TPMS 1 year and 8K miles ago. NTB My local tire merchant had difficulty setting up the TPMS devices and sent me to another of his stores who had a more sophisticated TPMS programming device. It took a while but he seemed to finally have success.
In the past 6 months the TPMS warning light comes on occasionally while highway driving, stating the system is not operational. After a short while the "Tire Light" goes out and works as it should. This past week the more detailed 4 tire TPMS showing very inaccurate tire pressures wheel by wheel, one not showing anything. (---). I reset the settings in the dashboard computer and after a short drive the warning re appears.
I normally manually use a manual gauge every 2 weeks to test tire pressure. And after testing using my gauge the actual pressures were accurate
My questions are: Do the TPMS gauges need to be removed re programed? Or could the main sensor control modual faulty?
Can anyone recommend an affordable ($300 or under) TMPS programming device that is not specific to their Sensors, and would work without removing the wheels/tires?
Thank you for any suggestions or comments.

NO TPMS PROGRAMMING ON MB

I got 14 years on my purchased-new w204 before it started throwing an intermittent light. As pointed out, just replace on your next tire change.

The ones on the W212 only lasted 10. Northern California all their lives.

What is the FCZ crest from?

The TPMS on my 2014 E250 with 257,000 miles are functioning properly and have not been replaced.
