Hi everyone,


apparently my new second hand summer wheels do not have any TPMS sensors in them, which is fine by me, but makes my car slightly unhappy.


Do you know if it would be legal to drive like this?


I could only find laws about the pressure (402/502, https://www.ch.ch/en/traffic-regulations-switzerland/, 100.- per bad tire), but some countries seem to have laws about TPMS itself.

Buy some from Ali BaBa

That's the plan for winter, but I'd rather not take all the tires off just to add those sensors just for 5 months if there's no need?

There's no need. Lots of cars around that still don't have them, no problem at all.

The car should eventually recognise the lack of sensors and switch the system off. It can take a while, especially if you're only doing very short journeys.

See more info here (in German): https://www.tcs.ch/de/testberichte-r...n/faq-rdks.php

Thank you!

Hello,

What kind of car and what year is it? Only asking as older cars actually have pressure sensors usually in the valve stems. Newer cars use the wheel speed sensors to calculate the drop in pressure as they turn slightly slower with a little drop in pressure when driving. When we top up the pressure in cars, gotta do a TPMS adaptation reset. This is either a button somewhere on the dashboard/middle console or in the onboard computer.

Anyway, as far as legality, it's really just a convenience feature of the car. Some cars allow to disable the warning altogether if the warning beeping/reminder is nirfig. Too many car variants to know which option are for what car. That's what you cars' manual and google is for, not to mention these forums too.

TPMS is just a marketing gimmick.
Low pressure can be easily eye balled.

Yes, actually I am confused

It's a Nissan Micra K13, the manual doesn't say anything about which TPMS is installed (plus it's in Italian, which doesn't help much )
Google says the micra is a cheap car and shouldn't have sensors in the wheels, but google also shows websites selling sensors for the micra.
Google says, if the light blinks when you turn the motor on, it means that the communication with the sensors is broken. It doesn't make sense, to me, that the light would be blinking if it was an ABS-based system.

Aaand I reset the TPMS twice after changing the wheels, it came back every time.

Tried attaching an OBD2 reader, too, but it wouldn't turn on when connected to the car.
But then if it's legal to drive around like this, everything is alright thank you again everyone!

Just be careful when/before crossing the border. Depending on when the car was first sold you may have to have TPMS sensors, it looks like they're mandatory if your car was first bought November 1, 2014, or later.

What? How? Where? Which border?

Countries have borders, there's one between CH and Germany for example.

I have a 2007 Ford S-Max with active sensors and you can't deactivate the system. F that. These devices spoof the sensors and put an end to the nagging.

Like many things, you can try to save money by not having them or bypassing the system. However if you are involved in a collision (your fault or not) and your vehicle is inspected, you may lose some or all of your insurance.

Roll the dice as you wish...
