TPMS & rotations of tyres

Page may contain affiliate links. Please see terms for details.
I've never had a car with TPMS.....but surely if you move the tyres around and then loose pressure in one of them than the car will tell you that the wrong tyre is losing air.....unless I'm missing something and the car knows which sensor is in which corner even without you telling it????

Which was my point, and with some systems this is indeed what happens. It appears MB systems do not work like this, based on other comments.

The car will "learn" the pressures in each tyre after a few minutes driving if you move the tyres around so no need to swap sensors around, at least not in any system I know of.

This was the case for many Ford cars during their change from DDS to TPMS, obviously before they decided it was too much admin and made the system better. Don't know if any other makes/models used this system, I can only talk from experience.

So how does it know the wheel position?....all the cars I've been in tell you which tyre is losing pressure (Front Right etc)....so how would it know without you "telling" the car which TP sensor is in which wheel? Just curious.
 
The Lexus system pings each sensor, so the
controller knows from the response time where each one is located
 
Thats clever.....
 
Ok

I've recently had the rear brake pads changed and next week the front. The front still have a couple of k's left in them but I'll get them done

About the tyre rotation, I was thinking about IE front to back and vice-versa

All 4 tyres are of the same spec/dimensions/pressures etc with up to three adult carloads

The TPMS is a 'Direct' system I managed to learn today, IE TPMS is placed in each tyre and I've seen them when tyres were changed. This system is more accurate and straightforward forward I'm advised as opposed to the 'Indirect' systems that run off ABS wheel sensor system

Reading the forum's various ones its confusing - but some comments here and gent with E class, mine is GLE/2016 - should be ok - aiming for next week Friday - all additional comments of help appreciated.


The direct tpms on my car learn as i drive car and give a reading after a few minutes driving and I'm safely assuming as all 4 tyres are the same size, it will be ok, no re-set etc required

I will look at the handbook tomorrow. Thank you all.
 
Rubbish. The sensors are not wheel specific.
This is correct, unlike fords sensors , which need training to the car , move the rims about at your peril with a ford . Unless you have the reset tool and know how to initiate the process it's quite technical, some of the newer sensors,you have to use a software program called ' forscan' and input each sensors unique id number , then move onto the next .

....Scroll back to my post jan. 08.

When testing TPMS systems I was responsible for I used a "Pinger", a handy little tool that could program each sensor by placing the tool next to the sensor and program it using the systems 125kHz "Challenge" signal and verify the settings by reading back values at 433 MHz.

Got one , £9 on eBay 👍👍

Hope this helps others:
Has 250d/GLE from new 2016 - current miles sub 22k, FSH by MB


Some may recall I had the rears done first the car had done just over 21k - used Brembo pads and wear sensor, forget the exact cost it was defo under 130 and I think it may have been 123 quid all in (had pads changed as wear sensor came on about 50 miles earlier)

Got the front pads done today - there was at least 5mm minimum left on them. I was surprised when rear pads went - got them changed
so I could have tryres rotated front to back and backs to fronts.


Front pads - plus tyre rotation cost 20 - total cost inc pads/Pagid (bremo on back) and break wear sensor 143 quid all in - still a lot cheaper than MB by a couple of hundred and fast fits about 70 to 100 quid

The car had never been worked o by a non MB technician until I got pads done

Tyre rotation completed - drove a minute, got reading - then a few mins later message reading "tyre ???? updating" I think it read and after a couple of miles I stopped and the same message then I think I pressed the ok button and gave me three options - I cant recall them, but one was factory setting and I chose that, all good.

FYI, my car had what they call an 'independent" TPMS, ie one in each tyre. The other types in older cars I think or cars that cost less take their readings off ABS

I hope the above makes sense - I will update it if I recall what messages came up - but all good - thank you all for your help

A few weeks ago, in mid Jan I obtained a set of wheels and Michelin winter tyres from Ebay, the seller said they were genuine AMG wheels with new tyres and tpms this appears to be true.
The tyres still had remnants of the labels on the treads so I would assume effectively brand new, the wheels have a little sticky residue in places on the faces which is coming off gradually.
I had the wheels installed and they where recognised very quickly and report pressures and temperatures by wheel.
The original wheels on the car purchased from Sytner mercedes in Weston Super Mare were after market hybrid forged wheels with Michelin ps4 but a staggered set.
The winter tyres have improved the ride as the profile is slightly higher, they have also removed the disconcerting skipping when manoeuvring when cold, the winter tyres are not staggered.
The car is an E63s estate purchased in October 2023.

Fitting winter tyres has ridden the car of crabbing at the front when cold ??

I’m surprised a main dealer retailed a car with aftermarket wheels. Result on finding a brand new set 👍🏻

Yes, I don't recall it happening at all since swapping the wheels and tyres.
Very helpful. Cheers.
 
They are probably better made and stronger than the factory alloys...... hard not to be! But I know that some value originality over performance and/or quality... which is fair enough.

This was also my experience when fitting winter tyres to my W213 E63s, but note different models and different winter tyres will have different levels of improvement regarding skip/crabbing.
I take it you are asking for your GLC, we have Pirelli Scorpion Verde all season tyres (all year) on my wife’s GLC and that doesn’t skip/crab.
