Want To Move Front Tyres With Pressure Monitors To Rear Axle

[PGrehan]

Hello all.

I have a 2011 Citroen C5 mk2 fitted with tyre pressure monitors. As the front tyres are near worn to limit but the rear tyres are OK, I want to move  the rear wheels/tyres to the front and then replace the worn tyres and fit the new tyres on the rear axle. I'm presuming that the tyre pressure sensor monitors fitted to each wheel are not location specific, and can be moved from one corner to another without problems, but I'd be grateful if anyone can confirm this.

I did a quick search through the forum to see if this question had already been answered, but did not find an answer - my apologies if I missed it.

 

Thanks in advance.

Just found this that might help or confuse you!

It seems that the pressure monitors need to know where they are and "be excited" using a Lexia!

Best of luck!

Thank you for your reply, Mike.

 

Since I made the original post I've had a few searches on Google to see if I could find out a definitive answer. Unfortunately I've not found anything official. There's nothing I could find in the hand book.

 

I found the link below

There's a post from Wheeler near the end of the above link which describes how the C5 mkII system works, and if correct would suggest that the car can "re-learn" the location of the rotated sensors on the car.

There are posts that suggest that a Lexia would be needed too.  I guess I'm going to find out which are right, as I'm scheduled to have the front tyres changed and moved to the back on Friday.

I'll let you know what happens.

 

Thanks again.

When having new tyres it is normal to have new valves. I am not sure about tyre pressure monitor valves but you may need to have a service kit.

In the end I didn't swap the front wheels to the rear axle and vice versa.

The fitter at the garage where I took the car for new tyres noted that the outer blocks had "irregular wear" (for more info on this, see link below), and that this may result in annoying tyre noise that would be likely more acute and annoying on the front axle. While I was not that familiar with this phenomenon, I vaguely recalled hearing something about this before, and as it happened I had noted some noise recently while driving that I was attributing as an early sign of wheel bearing wear.

The majority of my driving is on long motorway journeys at constant speed, which does correspond to one of the explanations for why this issue occurs per the link.  

Anyway, I decided to put the new tyres on the front axle and leave the rear tyres on the rear axle for the moment; I shall replace the rear tyres shortly. So, unfortunately I can't tell you for sure whether moving the wheels around the car would have caused issues with the tyre pressure monitoring system on the car.
