Tpms sensors

I have a 2014 GC Overland with the tyre pressure monitoring system. After three years, I'm due new tyres, but can't decide whether to replace the Tpms sensors.
Has anyone any experience with how long the batteries in them last?
Thanks,
Russell

Re: Tpms sensors

Anyone know how long they last or when they should be replaced. Mine are now coming up to 4.5 yrs and I'm about to change tyres!

Re: Tpms sensors

Seems they don't need replacing at all.

Re: Tpms sensors

Unlikely. The batteries have to go flat sometime. I changed tyres at nearly 3 1/2 years, deciding to take a chance based in the cost from the Oz dealers(and I didn't want to wait for shipping from the US). My tyre dealer charges about $30 per wheel for tyre removal and refit, so I figured it was worth the risk of having to replace them partway through a set. I also have some new ones I bought when the car was one year old, as I wanted one for a second spare, and bought 4 from the US as the shipping was a major component.
What I don't know, is whether the unused ones are gradually going flat (faster than shelf life that is), or whether they are inactive until,put under pressure, as is the case with the sensors I bought for my camper trailer Tpms.

On the other side of the equator, most tire/wheel dealers have rebuild kits for the OEMs that include a new battery, pretty cheap.

I have one installed every tire change mainly to avoid the inevitable nagging from the VIC.

Re: Tpms sensors

seems like tpms sensors last much longer than they used to. 15-20 years ago 3 0r 4 years. now id say 7 years plus.

Re: Tpms sensors

The sensors in my daughter's 2009 Chevy Colorado pickup are original. But in my Yukon Denali I replaced the first sensor with a dead battery at just 4 years old. Just had new Pirelli Scorpions put on my Summit and even though it's only 3 years old I had the sensors rebuilt while the tires were off.... cheap insurance.

Re: Tpms sensors

i think rebuilding sensors means remove and replace with nut washers and nuts. nothing actually done to sensor. think they do this because they can.
