Need help big time clarifying an outgoing issue
Ok, have a seat and help me and clarify me and suggest me. I am sick and tired of constantly getting my tire pressure monitor displaying warning messages in my dash.
I have had bad experiences with uneven worn tires (read my other topics). I think that I have one or more sensors bad but I don't want to get there yet. Here are a few questions:
Why do we have to inflate our C63 oem tires so high?, is it because the car weights too much? 42psi (F) and 45psi(R) seems too much compare to any other car I ever had . What tire pressure are you guys running?
Basically I ended having to "overinflate" all my 4 tires to high 40psi in order to shut the warning monitor up. I think I am driving with way overinflated tires and I don't see this safe.
what tires pressure are you guys running? what happens if I decide to put 20" rims with low profile tires ? does it change the PSI because of the tire shape and size or does it stay as the manufacturers specs because of the cars weight?
I am really ready to get me an aftermarket tire monitor system that can individually monitors each tire and display real pressure. Do you guys have it?
We carry an infant and a mentally and physically handicap child in the back most of the time so to me it is a matter of safety. Please help me with any suggestions. I had enough of this poor monitoring technology offered by Mercedes. Thnaks a lot!!!!!

275/ 35/18 Nitto 555 extreme in the back, stock size in the front. That is part of my confusion. Do you have to change the pressure because of different shape/size tires or what?

I run 39 F/ 41 R. I have Hankook 265's on back. I too hate the tire pressure issue. I wish our 09's had the actual tire pressures displayed. Would be very helpful. Do you lose pressure in all the tires or just one?

You set your tire pressure to whatever you want it at, and then reset the TPMS system to use the new tire pressures.. Problem solved.
It makes no difference to what size tires you use.

41 and 43. It has to do with just setting the current settings as default...sorry its such a headache for you but it has also been reminding me on my screen too...

I run no TPMS in the summer, and somehow it doesn't throw TPMS warning sensors. When I got new tires, it showed the warning message, I cleared it, and it hasn't come up again.
If possible, just disable the thing. Just check your tire pressures once per week manually, and disregard any messages that come up.

When you are checking your tires are they low? There is a bulliten out about interference with the control module causing the light to come on. You may want to check that out before you pull all of your hair out.

Didn't know this. Thanks!! It seems like I have two solid options in mind:
1- Lower the tire pressure and reset my dash
2- Buy a TPMS with a center portable display that shows you individual tire pressures.

1. Let the car sit for 6hrs or more
2. Set your desired tyre pressure
3. Turn on car and go into the gauge cluster settings and reset the TPMS value
This will set the new minimum value for the tyre pressure alert message.
Currently it sounds like your minimum value is set for > 40psi, that's why you keep getting the low pressure message.

TPMS is pretty sensitive to pressure changes. I get the message a lot and upon checking I have one tire for example that is 1 psi lower than it should be. No real life issue but the warning comes on. It happens a lot on a cool day that follows a warm week or on a rainy day. I like my new 2011 showing the actual reading for each tire. About time.

^^^ Thanks for your input, I think that you described the issue very well. I am wondering now if you could actually fit the 2011 model TPMS system on the older models so that it displays the tire pressure individually.
Has anyone done it? can it be done?

Second, knowing the pressure figures is nice but is useful mostly when you have an actual puncture. Consider the fact that when you get the warning every couple of months because of the slight pressure drop, you would probably check and pump all four anyway. Your original complain is not helped much by knowing that one tire is low by one psi. Of course that is just my opinion.

As I reread your original post, I realize that you have a safety concern but the overly sensitive monitors are being distracting.
Consider this: the car has multiple ways of warning you.
When you turn ignition off, it reminds you to correct tire pressure. This is the annoying message that can be ignored and has no safety compromise.
Then you can get a warning while driving about the tire pressure. This is still not disconcerting and can be addressed at the next stop. This has happened to me and the pressure was off by 1-5 psi.
I have also got a warning while driving that turned the cluster display red. This one I take seriously because if not a puncture, you may have enough of pressure drop that you shouldn't be on a freeway.
All of this is from my 09 MY. Read the manual about this and see what kind of warnings you get and how each meaning is different.
