I just got my Hummer wheels and tires installed. Definitely looks better now.

I was prepared to have the TPMS activate on me as soon as I started her up, but I have driven it for two days now and nothing; no light, no chime, no nothing. The TPMS light comes on with the key, but goes off after the two-second or so system check.

When I first got the truck the TPMS would not stop going off, and now it seems to be dead. If so, I am NOT complaining, but do you think it is malfunctioning? Seems like it to me. Thanks.

 

you know, my wife's volvo xc90 did the same thing. I switched rims and tires for winter and the TPMS did not activate for 2 weeks. Then, out of the blue, the TPMS light comes on.

 

Man, just when I had hope I'll keep an eye on that but wonder if anyone else had had their Dodge do this?

 

Did you install the sensors in the valve stem of the H2s? Are you running a load range E tire? What cold psi do you have the tires at? If everything is properly installed and you have the tires aired up above 60psi in the front and 45psi in the rear then maybe everything is just working properly. There could have been an error in how the sensors were mounted in the factory wheels and, by changing them into the H2 wheels, you corrected the problem and now everything is functioning as it should...

 

I just installed the Hummer tires and wheels. I didn't change valve stems or anything. The Hummer tires are BFG TA's, LR "D", with a 50 psi max inflation.

Is installing the factory valve stems in my new wheels and inflating the tires to above the minimum recommended factory pressure all I have to to get the "factory" TPMS working with my new setup?

 

Are your factory wheels and tires in the bed of your truck? That seems weird to me that you don't have the sensors in the new wheels and it isn't throwing the TPMS light on the dash. Heck, if that is all there is to getting the dash light off I might just be throwing my sensors in the garbage (or on eBay)...

To answer your question, yes in a way. Installing the TPMS sensors and inflating your tires to max pressure should make the TPMS work; if by work you mean throw the warning light on the dash and make 2 "dings" every time you start the truck. The load range D tires with a 50psi maximum are still 10psi under the pressure at which the TPMS is programmed to trigger an alarm for the front tires (60psi for the front tires, 45psi for the rear tires). The factory tires are a load range E with 80psi max inflation so are capable of these pressures. Your new load range D tires are not, and presently there isn't a way for the dealership to adjust the psi at which the TPMS throws a warning.

 

The factory tires and wheels are stowed in the back yard. Thanks for the clarification on the sensors. I plan on getting some 65 psi D's or some E's once these tires wear out. If I get something with at least a 65 psi max, I'll probably have the factory sensors installed in the new wheels.

If the light comes on, the red neck in me thought about welding caps on both ends of a piece of tubing, drilling and installing the four sensors in the tube, inflating it to 80 psi and throwing it in the bed

 

nothing redneck about that. i feel that the TPMS is a useless system for those of us that actually THINK about the vehicles we trust the lives of our loved ones and our own in. I don't know about anyone else, but I check my tire pressure at least once a week, always have. The TPMS is just the tire manufacturers watching their backsides after the Firestone/Exploder fiasco...

 

I check my pressure often, and look at the tires (give them a visual) every time I get in the truck. I have never had a flat, or any other tire problem in my life; at least not that I didn't discover and fix before anything failed.

I do see a lot of people driving cars though that are clueless about tire care and pressure. I just cringe and change lanes.

 

*********UPDATE*******************

The TPMS light finally came on today. The wheels left the truck six days ago! If that's any indication of performance, I wouldn't rely on the TPMS for much.

 

Does anyone know where the TPMS receiver unit is located?

I can not locate it, and I am unable to find any location information on the internet...
