You can damage the sensor using the automated bead breaker on the tire changer if you position the breaker head right by the valve stem. Gary |

Seen it happen on a Saab. Non-RFT tires, of course. Ripped the sensor right off and cracked it.

I did have one sensor go bad after having my wheels refinished over a winter, but it was one of the ones that was damaged, so I don't know if it was the battery going dead or the sensor corroding from having the case broken. Given the cost of mounting/balancing tires, if I have to dismount a tire that's more than 3-4 years old, I will purchase a new sensor from Tire Rack ahead of time, as replacing a single sensor later with a dealer part and paying for 1 wheel mount/balance will be about the same as all 4 from TR. AFAIK the TMPS kit is only seals and maybe a valve core. It is only required when the valve stem is removed, but some shops may insist on replacing them when changing tires anyway again as "cheap insurance." |

You have been misinformed. If they knew that they were doing, they would never trash a sensor. It's possible, but only if you don't follow the safety precaution or they do not know where the sensor is. The only thing the tire guy has to know is to not break the bead directly in the path of the valve stem (for bmw and lexus). BTW, I'm not a professional, but I have dismounted four lexus wheels and did not damage the TPMS. I also replace the runflats on my 335i yesterday and didn't damage the tpms sensor. I didn't break the sensor because I knew where they are under the tire. Also a flat will not necessarily damage a sensor. If you hit a pot hole or rock and the force of impact is right under the sensor there is a slight chance you may damage it. It's tucked well under the lip along side the rim surface. But 99% of the cases, a flat will not damage the tpms. BTW, I do agree on one thing: if you are leaking at the valve stem then replace seal with the seal kit. But why would a valve steam leak trash your sensor? Gary Last edited by garyhgaryh; 11-04-2013 at 12:52 AM.. |
