Hello
I was considering the rotation of tyres on my GLE - front to back and backs to front

Will I have to do anyhting to reset TPMS on the sash etc and if so what do i need to do

Thinking of taking it to a garage and giving them 20 quid
 
You should just be able to change them. I change winter/summer tyres twice a year and you only need to confirm the new pressures.
 
Even tyre wear? This means you can replace all 4 tyres in one go, which is a plus.
Hi
Yes, the inside front of both tyres wearing I've noted. Rainsport 5 - got these on in Oc 2020 height of covid,

Only dont about 4.5k miles on them
Had the car recalled for a steering rack and they initially messed up the tracking ie pulled to the right but it was corrected on the second attempt

Therefore I thought it must be them again - car was tracked/done about 9 months ago

However, looking at the mot (had the cr from new 2016 22k on the clock now) - the orginal tyres, Dunlop Sports Maxx i think they were were also wearing on the fronts insides So possibly a messed up trait of these cars

Thinking of moving fronts to back - not sure if the currecnt tyres are directions and if not may swap left to right front

That was why I asked why the Rotation.

My Tyres as far as I know are different Sizes width wise and Directional! :(

Might be a stupid question, but, AMG line cars usually have different wheel sizes/ tyre sizes back and front ??

Thank you all

My car/GLE/Amgline, all 4 tyres are the same size and pressures
(The c class cars I had before were the Avantgarde and had wider wheels/tyres at the back and different pressures

The GLE, all 4 tyre pressures are the same

Therefore, do I/they (tyre changers outfit) need to do a reset anything and if so, how, please?
Thank you
 
If your car shows individual readings and/or displays individual alerts for each wheel, as opposed to not showing individual readings and giving a general low pressure alert, then I suspect you would need to swap the front valves with the TPMS sensors to the back and vice versa, otherwise the car will show rear pressures for the front and front for the rear.

Not true, doesn't matter which wheel goes on which corner

Your car should adapt and 'learn' the signal each sensor is putting out, usually within a few (~10) miles of driving. I had new TPMS sensors installed in a set of winter wheels and tyres, no issues when putting them on the car and again no issues when re-installing the original summer wheels and tyres.
 
I guess it depends on the system fitted but mine has a menu option to reset the reading after inflating the tyres to the correct pressure.

Rubbish. The sensors are not wheel specific.
 
Thanks all. To be very clearm I intend to have the 2 back tyres moved to the front and the front to back.
All 4 tyres are the same size and same tyre pressures

My TPMs automatically reset to the current reading, eg had a slow puncture, got an alert, filled the tyre up and the reading was showing the normal tyre pressure in units. The car is a 2016 GLE, AMGline and not the AMG petrol suv.
 
There are three types of TPMS:

1. One that checks for any unbalance between wheels on the same axis.
This "primitive" system reads the ABS sensor pulses. A flat tyre rotates faster
which will trigger a warning. No actual pressure is measured. (This
is really only a warning system but very cost effective as it does not
require expenceive sensors.)

2. One that simply reads all 4 wheels sensors as they transmits and sets a warning if any of them
runs flat. It is up to the driver to stop and check which one that is running flat.

3. The best (most expenceive) system is the WBL "Warning By Location".
Each wheel house features a 125kHz transmitting antenna that challenges
(or "pings") the transponders in the rims in a sequence. One by one they report back:

- Temperature of the rim.
- Pressure in the tyre.
- Battery voltage
- ID

The algorithms are based on the fact that cold tyres have lower pressure
than warm. As the tyre warms up during a ride, the pressure increases
which is normal. If the pressure does NOT increase, this means a small leak.
If the pressure drops during a ride and the temperature is constant - then
an alarm is triggered. There are also functions that monitors the tyres
during standstill as well as putting the sensors into deep sleep if no
motion is detected for a long time.

If a car has a display clearly indicating location and pressure,
then its system is the WBL type.

Changing between winter and summer wheels means that the system does
no longer recognizes the sensors. The new ones has to be learned again, an
automatic procedure which is initialized as soon as the previous sensors
cannot be seen by the system. This takes a few kms to complete.

The WBL is often used together with Keyless entry and go since both of them
uses the same 125 kHz challenging frequency. (Car to wheel). The sensors
then transmits back at 433 MHz (wheel to car), same frequency as the keyfobs
normally uses (there are system using 868 MHz as well but I have only encountered
keyfobs using 868. In the USA, 315 MHz is used for keyfobs. (Uncertain if this
frequency is used for TPMS.)
