    TPMS maintenance at time of tire replacement?

    OK, I guess I'll never get the Pilot 4S tires due to my 18" wheels, so I broke down and got a set of BRIDGESTONE POTENZA S-04 POLE POSITION SL from TR, delivered to the local installer. Just finished swapping off the winter tiresicon/wheels in the garage so I can soon get the new tires on.

    This is my first car with TPMS. Should I be doing anything like having the batteries in the TPMS replaced at the same time? Car is 4.5 years old, 34K miles, OEM tires on the front.

    They do have batteries, right? And I presume only accessible from the inside?

    TPMS batteries are not a serviceable item. The complete TPMS unit needs to be replaced when the battery dies.

    2015 car - you're fine unless they get broken changing the tires out. My truck is a 2010 nissan with no problems in 110k miles, and my cayman is a 2006 that hasn't yelled at me yet...

    The sensors haven't yelled at me yet. The tires have... 3rd set of tires going on in a few weeks. Hoping I didn't just jinx myself!

    Re: TPMS maintenance at time of tire replacement?

    Good info, guys!

    I would have kicked myself if I neglected to ask and a few weeks after tire installation, possibly needed to de-mount the tires to replace a $2.99 battery.

    Re: TPMS maintenance at time of tire replacement?

    The TPMS sensors generally don't have replaceable batteries. You have to replace the whole unit if one fails. I have heard of people removing the sensors then digging out the epoxy potting material that seals the battery in the unit then putting a new battery in an repot the material.

    From my experience 8 years is pretty good for their battery life. I read an article that said in the future the sensors will be battery free but that is way in the future.

    You can replace the valvestem portions of the TPMS sensors if they get chewed up. I replace mine every few years, but I wear mine out pretty quickly adding/bleeding air for autocross. I'm still on the original actual 10-year old TPMS sensors, though.

    Re: TPMS maintenance at time of tire replacement?

    My local tire shop charges a couple $ to change the o-ring on the TPMS. They say it is required (?). I don't argue.

    Original sensors on my 2013 BS and the 2010 Volvo.

    I added a new set to some 987 track wheels for ~$140. Synced up immediately, no issues with readings.

    Re: TPMS maintenance at time of tire replacement?

    TPMS are kind of like regular car batteries and last like 6-8 years. If I was getting close to that and doing a tire replacement
    I would replace them so as to not have to have the service labor cost again.

    Wow! I think TPMS was optional for 2006 on the Cayman. Are you sure you have TPMS?

    I found a website that sells for about 1/4 the Porsche price. Went with those at about year 4 since I figured I wouldn't make it to year 8.

    Hmmm... I'm seeing Pilot Sport 4S tires in 235/40/18 and 265/40/18 at TireRack. You can even get the "N4(Porsche)" ones for about $10 more per pop.

    Didn't come up on my TR website search, nor in conversations with my long-time TR rep.

    Anyway, I see differing opinions on the TPMS and at the car's 4.5 year age, I guess I'll be risking it. Picked up the car last night on the new tires but only drove home 2 blocks from the installer, and the original TPMS sensors are in place.

    MAYBE I'll be disappointed by the tires' grip but I suspect not. What I do recall that I didn't like, of the various recommended tires, the Pole Position was the heaviest and I "have a thing" about unsprung weight.
