Tyre Pressure Monitoring Sensors - Rotating or winter wheels

[snotrag]

Hi all - first time Mercedes owner, just bought a W212 E350 (2010) - can anyone confirm, these use a TPMS system with sensors in the wheels? Previous cars have just used the wheel speed sensors/ABS system.

If so - how does this work when you want to

A) rotate your tires around the car for wear (I'/e move fromt front left to rear right)
B) Have a second set of wheels and tyres (I usually have a summer and winter set)

and finally

C) Can you re-use/re-install the sensors when you have a wheel refurb?

Thanks!

We have a 2015 GL with TPMS sensors in the wheels. I purchased some used wheels and winter tyres from German eBay which already had sensors, and the car recognised them without issue. I don’t rotate tyres but I had new tyres fitted to all 4 wheels last autumn, and the wheels were put back on the car in random order, and again the car didn’t have any issue with identifying wheels. I haven’t had the wheels refurbed yet, but I can’t see why they won’t be reusable, although they may need new sealing washers / O rings whatever.

My 2014 e class does not have sensors.
On my other car which has sensors it can display individual tyre pressures but my Mercedes only warns me if it thinks one has dropped pressure (based on rolling radius I presume).

Does your car give you actual tyre pressures?

Are your valves normal rubbery ones or metal TPMS ones?
They are noticeably different!

Thanks all, it seems there is the standard (abs sensor type) system and the actual wheel sensors to report actual pressures that were an optional upgrade which mine luckily doesn't have!

If you have TPMS you should be able to find an actual pressure reading in one of the OBC sub menus. A low pressure warning system ie one using wheel speed sensors won’t be able to record actual pressures.
The graphic displays pressure at each “corner”, so it won’t matter how you rotate tyres (assuming of course you don’t have directional tyres and/or different front/rear wheel sizes).

I got 2 x new rear tyres fitted on my 2017 CLS this week - has TPMS with the metal valves, pressures shown individually in the OBC sub-menu.

Noticed afterwards the fitter had swapped my rear wheels L-R and vice versa (as one of them has been refurbished so looks slightly different), however the TPMS correctly recognises which corner they are now at. I tested it as the tyres needed another few PSI so did them one at a time and the OBC reflected the changes correctly.

Can't imagine he swapped the valves from one wheel to another, so unless there is a procedure to 'reset' the sensors that I didn't see there doesn't seem to be an issue rotating wheels with TPMS.
