Seriously...TPMS?

[Soundguy]

A thousand wonders that some of us old farts are still around. I was taught to keep a check on my tires, not to put small toys in my mouth, not to stick anything into a 110, etc, wall outlet,,etc, etc,

yep.. don't run with sharp object unless charging tghe enemy.. and check tires, oil, hoses and belts before starting a vehicle / engine.

My very sweet mother said, "don't stick anything in your ear smaller than your elbow"

you can rotate without resetting anything the vehicle wont know the difference, some vehicles will tell you tire location, some don't. the g.m. vehicles that give position can be reset w/out tools. trucks that have differernt pressure front & rear (ie e-250 60-80 psi) will trip the light when rotated, but the reset procedure is in the vehicle owners manual. I only have a tpms reset tool because it came with my scanner. very rarely gets used.

I get oil changed and tires rotated as soon as my DEF alarm starts going off on F350 KR at my Ford Dealer. As noted above, fronts set to 60 psi and rears set to 80 psi. The quick lane wizards ALWAYS reset all four tires to 60 psi after rotating. I have given up on driving all the way back to dealer to get corrected as they just don't learn anything from my 150 mile round trip. I just add air to rears and move on. DUH!

And.... the sad part is..... most of the people who never checked their tires before, will still be driving around with the TPMS readout showing 5 psi. Not sure much is gained. With LT tires, if you inflate rear tires on a pickup high enough to keep the TPMS happy, then if you mostly drive with an empty bed, you can end up wearing out the centre of the tires. TPMS computer is happy, but you end up with prematurely bald tires. Did I miss something, do pickups today need help becoming tail-happy ? Rgds, D.

Exactly, why can't common sense become more prevalent?

Oddly enough, despite what the owners manual says, I drove 30 miles round trip tonight and no TPMS lights went off even though the manual says they must be re-calibrated with a re-set tool...Who knows what's up with this.

Supply and Demand prevails..... enough so that I've taken to calling it UNcommon sense !

Many people prefer to insulate themselves with technology, instead of taking direct ownership of an issue.

Up here in salt country, many of the sensors don't last too long. Some of them are now old enough that their batteries are coming due. Often they are easily damaged when tires are being changed.

All this because people are too lazy to use a $6 manual pressure gauge.

Have 2004 Chrysler Town & Country Limited it has TPMS but it does not track position it just tells you if a tire is low, switch to snow tires with sensors and after a few miles above 25 when the sensors start updating quicker it logs the new sensors.

The 2006 Jeep Commander Hemi Limited I have has a TPMS system that keeps track of pressure and location of each wheel including the spare. When you rotate tires or change out to snow tires with TPMS sensors the vehicle has to relearn or train the system. The Jeep does this by having transmitters in 3 of the 4 wheel wells and will command each TPMS unit to send a signal when requested and it logs the new id number and the pressure for each position the 4th one is set as the last remaining position and the one that does not come on at the 25MPH speed and is not rotating is set as the spare.

Got a SuperChips 3875 tuner for the JEEP to tune, reset the N23 recall controller problems but it also has the ability to change the TPMS pressure settings for when off road or going to the sand dunes (need 12-14PSI there).

Also have heard the newer RAM pickups have a switch for empty and loaded to change the TPMS levels. Have a TST system on the 2005 Dodge RAM with 6 extra stem mounted sensors for whatever trailer I am towing.

Some cars have a manual retraining procedure and to get the transmitters to send their code to the receiver when it is in retrain mode it can be done three ways, driving above a certain speed, using a transmitter to transmit the activation request to each unit, or using a magnet around the stem of the TPMS unit to close a reed switch activating the transmitter.

We had people who did not check their tire pressures....ever!

We had a series of vehicle rollovers that were attributed to low tire pressures because people were too busy or didn't know how.

So the only way to protect those who know better from those who don't care or know better was to require TPMS. Now if we would stop calling 'accidents' accidents and laying blame or responsibility where it belongs the world might be different. But we have a 'no fault/no blame' society more or less these days.

Maybe I missed something...Who or what is 'requiring' TPMS?

Nevermind. The nanny state at it's best. We get what we vote for. I trust no one who is complaining about TPMS, indirectly voted for it. There's also a current push to mandate backup cameras.

"The Firestone and Ford tire controversy|Firestone recall]] in the late 1990s (which was linked to more than 100 deaths from rollovers following tire tread-separation), pushed the Clinton administration to legislate the TREAD Act. The Act mandated the use of a suitable TPMS technology in all light motor vehicles (under 10,000 pounds), to help alert drivers of severe under-inflation events. This act affects all light motor vehicles sold after September 1, 2007. Phase-in started in October 2005 at 20%, and reached 100% for models produced after September 2007. In the United States, as of 2008 and the European Union, as of November 1, 2012, all new passenger car models (M1) released must be equipped with a TPMS. From November 1, 2014, all new passenger cars sold in the European Union must be equipped with TPMS. For N1 vehicles, TPMS are not mandatory, but if a TPMS is fitted, it must comply with the regulation."

Well I always knew what PMS was but did not know that tires suffered the same symptoms.

When rotating do we also need to respect gender as well?

Hadn't heard about the switch on the RAMs - about _______ time something like that was implemented.

Some people (like yourself) will take the time/money to make sure that this system keeps working as intended. For the "problem children" (drivers) that this legislation was intended for, many of them won't bother as soon as they actively have to do something and/or spend money.

Sensors can be in the $100 range, up here. Upon hearing the price, some people just replace them with regular valve stems.

A perfect example of government officials doing a static problem analysis, i.e., they don't contemplate people will change behavior in response to new laws and regulations.

1. People are not maintaining the proper air pressure in their tires and causing x deaths per y miles driven. (insert a very low number for x and a very high number for y)
2. Mandate an expensive solution layered with regulations.
3. Problem solved....until there are problems with the solution or people have to spend additional money to maintain it.
4. Return to Step 2.

I would be so easy to mandate to have the system be user friendly with a push button to rescan and display the issue in the display. They could actually easily add the mil codes too and get rid of scan tools all together.

No offense meant...

1. How would the regulations define 'user friendly'?
2. All technology specific requirements would be out of date before the ink on the regulations was dry.
3. Items 1 and 2 is usually what's done, i.e., when all else fails, increase the micromanagement.

 

[yelbike]

My recommendation isn't perfect but neither is the current crap of scan tool for mil and another scan tool for tpms.

 

[GPintheMitten]

I have TPMS on my 2007 Jeep Commander. I have a display for each tire's pressure indicating its position on the vehicle. No problems when I rotate. I think it gets its position from the reader in the wheel well and only get's the air pressure from the unit inside the wheel.

I like having it.

Back in the day we called these things Idiot Lights.

 

[timswi]

Looks like they also sell a $70ish one ( Kent-Moore EL-50448 TPMS Tire Pressure Monitor Sensor Activation Tool : Amazon.com : Automotive )and its only 2011+ Chevys that need it. One would think that they could do it through the information center... Whats the point in putting a computer in there if you don't use the it???

Aaron Z

Thanks for the info..Just ordered one.

Unfortunately the idiots got worse and now I guess we need fancier idiot lights.
