Who switched the sensors to the new wheels?

 

Uh, if they are "run flat tires" why are you concerned about a flat and getting stranded?

 

The HHR doesn't come with EMTs, only the system to warn you of low tire pressure.

EMT tires don't HAVE to be replaced unless the sidewall is cut or broken from improper installation or driving on the flat tire for an extended period of time. The repair procedures for modern EMT tires isn't much different than regular tires except for the mounting procedures.

 

A runflat tire can only go a pre-determined amount of miles (I think around 50) with out air in them. That is why they need TPS to monitor them.

 

Moving the sensors from one set of wheels to another should not be a problem. We have been doing that since they were first introduced by Chevy. It is as simple as unscrewing to nuts, first the outside and then the inside. GM states the seals should be replaced (2) when changing the sensors. I just read that today and to tell you the truth, we haven't ever changed them. I guess it is insurance for leak prevention.

 

Most NEW STYLE after market wheels will accept current TPMS with a relief cut out on the wheel by the valve hole.In some cases the wheel does not have that relief cut; there are several retro kits available to install the sensors. GM uses two different types, one is a rubber valve with the sensor screwed to the bottom of the valve, some are metal valves that are bolted onto the wheel through the valve hole. Yes the rubber grommet and the valve core need to be replaced anytime you remove the tire. The grommet to prevent any leaks and the valve core to prevent BI-Metal corrosion. The valve core should always be replaced with a Nickle core and not the traditional brass valve core. Also you should never put chrome valve caps on these sensors because they too will cause BI-Metal corrosion and will ruin the sensor.The plastic or aluminum valve caps that have a rubber seal on the inside are the best to use. Every one of my customers with TPMS has their sensors rebuilt by us. In most cases its free. Some sensors require a special kit to rebuild at a cost of around $5.00. Always remember to "Relearn: your sensors after any service has been done so that the sensors are in the right spot, that should be done for free using a simple scan tool.

 

I'm aware of the procedure to change the sensors. See my sig

What I was getting at, is if the sensors were programmed correctly. If someone other than the dealer installed them, then they might not be aware of the proper method.

I went to Firestone first, because they are nearby, and they didn't know, so I went to my dealer and they were able to. Shortly thereafter, I found out that it was in the owners manual.

 

a local shop did the switch, maybe he got three out of four right. i took it to two different tire stores, and they said maybe a bad sensor.

 

Wish you was close to me. I'd solve that problem. For free!

 

Humm...i'll have to check that.

Haven't been back here for a while, but thanks for the replies everyone.
