from what I am seeing the sensors are very touchy. When we got our RT Oct 31 I checked all the info and on the tire pressure page it was 31 31 32 32 never noticed it changing much sometimes 29 30 32 33 sometimes 31 31 31 31. About a week ago I had to get my daughter and it was about 15 degrees out the alarm chimed LOW PRESSURE and they were flashing 30 30 30 30. I picked her up and it was 32 31 31 32 still flashing. I checked the air and filled to 34. the gauge said 33 33 33 34. I havn't had it alarm on me again but keeping an eye on it until spring. Very touchy.

If you expect the temps to be that cold for a while, go ahead and bump tire pressures up a couple pounds. Remember that tire pressures drop one pound for every 10-12 degree drop in temperatures. Another thing to watch is adjusting tire pressures in a garage that is warmer than outside temperatures. I see this problem at work every day. It's 65-70 degrees in the shop and 25-30 degrees outside. That will make a difference of 3-4 psi after the car is pulled outside. Also remember to check the tire pressures before driving. As you drive, the tires will warm up and increase pressure by a few pounds.

Personally, I hate TPMS. I am still trying to figure out a way to mount all four TPMS sensors in a spare tire so I can run regular valve stems on the four road wheels and not set off the TPMS warning light. Mounting the sensors to a wheel is easy, but mounting them in a way that still allows mounting the tire to the rim without damaging the sensors is the trick!

I gotta agree: This is something I would rather do without. Admittedly, it might be useful on an SRT or an R/T where you're actually likely to race the car, but on an SE? Give me a break. The SE's good, but I don't think you're going to run the risk of shredding the tires off the rims even if the air pressure is low when you go off the line. To me, it's just another annoying electrical device that can go wrong.

I was told that all you have to do after a tire rotation is to drive above 15MPH for a few minutes and the receiver would learn the new location. No re-programming necessary. Dodge vehicles after 2004 were supposed to be set up that way. The owners' manual doesn't say anything about reprogramming in the areas about TPMS or tire rotation. So, I can't point to you anywhere to go and find out for sure.

didnt know about the auto reprogram, make sense though (Great Info). For you really smart people that understand Elec Lingo, I believe there is a page in the hidden EVIC program where you can adjust the minimum warnings, I dont understand all the lingo in the hidden programs, but someone may want to check it out. See the EVIC info needed thread on how to find the program if you dont already know.

What's the curb weight of the SE? And if you're running the all season tires with softer side walls which heat up more the risk increases. Honestly, I don't like the added complexity of the electronics. I just wish they worked better and more dependably.

Temperature has been dropping here as well. I got a alert that both of my left tires were low. I went to the station and topped them off, but the alarm took several minutes to register the change and go away. Does anyone know how often the sensors update?

I agree TPMS sux. I am headed back to the dealership this morning with my original 18 inch wheels so that the TPMS senors can be removed and installed in my 20 inch OEM, chrome clad wheels. I know I have posted this before, but the TPMS sensor from the 2008 Dodge Charger with 20 inch wheels will not work with the Challenger. The part numbers are completely different and if used they will trigger the dreaded tire sensor light and it will stay on whenever you are driving.

Obviously, there is only one solution to this whole problem: Disconnect the TMPS light.

The curb weight is listed as 3720.
