Time for new tires @ 16000 miles . I was thinking of replacing one of the sending units on a slowly leaking tire. If it is leaking does the warranty cover the replacement? Dealer quoted 200 dollars a corner so if I replaced all of them it adds 800 dollars every tire replacement cycle. Judging from some of my other dealer quotes I bet you guys are paying 150 or less.

 

16,000 miles is really good. IMO. For tires. Not TPMS.

 

I'm not sure about the warranty. There is a TPMS rebuild kit that replaces the seals and "guts" of the valve stem.

 

When I had my Michelin SS put on at Costco I believe I paid $18.00 per wheel. A call to Costco will clear it up.

 

The TPMS should really never be replaced unless it's bad. Batteries and seals on the other hand can be replaced. If you drive your car on salt covered roads .... the salt really does a number on the valve stems so you might need to rebuild them sooner then someone in the south. I only rebuilt one set of TMPS on my past Audi and that was after 4 years of ownership (4 sets of tires).

I would get the one checked/replaced that's leaking by but the others should be good for a few more years. Most owners on here won't have their cars long enough to worry about even the batteries going dead in the sensors.

 

I do not see why the new car warranty would not cover the TPMS units if they are faulty. However, it sounds like you are choosing to replace them as preventative maintenance in which case there would be no warranty coverage.

Based on my past experience, you should be able to get at least 3 or 4 years out of the TPMS units.

 

I have never had to change a battery yet or rebuild a TPMS unit in any of the cars I've had with them yet. (As #5 mentions, the longest I had any recent car with them was around 3 years)
The big tire stores like Discount Tire will try to upsell you rebuilds on every tire change, a polite no thank you to that, it's just not necessary. Replace/fix them when they break, not before.

 

yeah they last about 4-5 years (battery)

 

first of all the defective TPMS sensors are covered under the basic warranty.
They can last upwards of 7-8 yrs!

a sensor went bad after just 2yrs and the dealer covered it.

I got 6 years life on my Cayman S.

 

Thanks everyone who responded. Interesting that my service advisor tried to sell me one that should be covered under warranty.

 

I like to change the valve stems with each tire change.
They are only $20 each for the kit.
Since they build up brake dust residue, I like keeping a clean look on the wheels.
(You can get black ones if you have black wheels.)
If you have a TPMS, leak valve stems would fix it.
No need to change sensors, unless they are reading bad, and they would be warranty, in that case.

 

Just to confirm, if I move my TPMS to a new set of wheels I only need the replacement valve stems?

Eight years on tha wifes tpms, boxster. If it ain't broke...

 

My understanding and experience is that 5 or 6 years before the batteries in the TPMS start to give up is typical. Like everything, there's always expeditions, but if you're in the "window" and replacing tires anyway, put new sensors in. The price is only about $160 for Huf Intellisens sensors from Pelican Parts. And that includes new stems.

The alternate is to wait for the TPMS to go bad and then pay $160 plus the price to install the sensors and rebalance your wheels. Consider it preventive maintenance.
