How many of you replace them when you get new tires? I have an 08 with 15589 miles and just about to need tires. Thanks guys!

If you want to spend the money, go for it, but they should last a lot longer than that. The only thing I can think of that could damage them sooner is using something like fix-a-flat. The stores will probably try and get you to buy them or even try to sell you the TPMS rebuild kits, but I always pass. Between my C5 that I've replaced the tires 3 times, and my C6 that I've replaced the tires twice, never a problem with TPMS.

 

Lisa, I replaced one of my tire pressure sensors at about 30K miles. It was stuck on a pressure reading and did not change. Another indication of defect is no reading from a tire(s) on the DIC. The owner manual states that there is a 10 year life on the battery in each sensor. I'm sure there is a variance to the number. changing a sensor without changing the tire is no biggie.

 

Still on my original TPM on 2005 on second set of tires.

 

I have an 02 C5. The sensors are still working fine. My 09 C6 had one sensor go bad with an intermittent reading of zero psi when the tire was fine.

 

Still on my original TPM on 2005 on second set of tires and 32,000

 

I had one TPMS fail on my 2005 at 77k miles. Build date on the car was 9/04.

 

Still on original TPMS on 2001 C5. No problems on the 2010 GS either. Batteries should last 7+ years - assuming no damage because caused by mounting or "fix-a flat" goo.

 

51 months and 23,000 miles on my original sensors. Based on the life of the sensors used on my C5. I expect to go past 9 years & 45,000 miles before needing replacement.

 

Thanks guys don't want to spend the money if its not needed. Now I can use that money for something else

The battery will last much longer in low mileage cars, as the communication frequency is far less when parked than when moving.

The ten year estimate is for people who drive the average 12-15K annually. I'm currently at 102K with my '08 (about twice the average) and will change sensors at my next tire change around 110K, simply to avoid a possible problem before I hit 140-150K.

 

As mentioned, really depends on how much the car is driven, as the sensors pretty much lay dorment when the car is sitting. I've pretty much embraced the TMPS set up, as invested a few buck's in the reset tool. Have three cars with TMPS, with two sets for the Vette(track), and two sets(winter) for my daily car, plus wheel rotations. Really can't see not having the tool, as also indicates a faulty senser, which is more likely early on, than one dying after many years.

 

Since I've had an OEM sensor go bad after 3 years, I'm taking a different approach. When I get new tires and my sensors are 4+ years old, I'm going to buy new sensors.

I have purchased good aftermarket TPMS sensors (Orange Electronic brand) on Amazon.com for about $30 each...so that's roughly $120 for a set. When you have your new tires installed, the shop should "rebuild" your existing TPMS sensors (which basically means they install a new rubber grommet and replace the installation nut). This service costs $5-$10 per wheel and is considered to be good preventative maintenance.

So I figure it's at least $20 to rebuild your existing sensors...or $120 to go with new aftermarket sensors. That means the new sensors really are costing you $100 more than you will already spending to reuse your existing sensors. That's not a huge expense when you are dropping $1,000 on a set of tires. And there's a reasonable chance of selling your used sensors for at least $50 because someone is always looking for a cheap set of OEM sensors.

Hey...there's nothing wrong with rolling for 10 years on the same sensors if they last. But the cost of installing new ones isn't that great if you approach it the right way. Just a thought...

 

Discount Tires have some kind of service for the TPMS. When I got new tires they didn't push this service on me.

 

Interesting question.

Supposedly in 'average' use they're good for 10 years, limited by battery life; however, some have experienced premature failure.

Mine are at 7 years old and 71,000 miles with no problem, but I might be convinced to replace them at 10 years, or the nearest tire change to that age, but not before unless they fail.

 

Me too.

 

almost at 8 years (2005 purchased Nov '04), on 5th set of tires at 133,000+ miles. never "serviced" the tpms during tire changes. but i do notice 1 of the rear sensors are taking longer to "update", so it probably won't last too much longer.

 

I wonder if the batteries can be replaced on these.

 

Their designed to last 10 years. So some will last 10+ years, while others will begin to die in 7-8 years.

The ones on my 2004 Yukon started dying at 7 years. (one)......then months later a second. So when I had new tires put on they repld all of them.

They used aftermarket sensors. Two of them lasted 8 MONTHS or less. So, finally Discount Tire ordered GM sensors and I've not had any more issues.

So, figure 7-8 years likely life span of most.

 

No.
