Tyre pressure monitoring sensors TPMS

Just get them fixed if they indicate a warning.

It’s not only a great safety feature, it is also good for the environment and ensuring emissions remain in check. And finally they can save money by making your tyres last longer.

I like them on our cars.

Hold down button on dash for 2 seconds, system resets...

Love it   

Seriously though, I've got the ABS version and it did alert me to a tyre that needed pumping up. But can give false alarms.

Yup I’ve had it a few times on my golf r when hitting a pothole that the system gives a false reading. But rather have that than nothing at all.

TPMS isn't there so you don't have to check your tyre pressures until the sensor alerts you. I've seen them not alert until tyres are at least 4 PSI down. I would rather check my tyres regularly, like has always been advisable, and know I'm not causing any unnecessary wear because they're all out of spec for long periods of time.

Motorbikes don't have them yet, at least not the bikes I've owned, and we're doing just fine without them.

The version I was talking about displays the actual tyre pressure for each wheel.  So unless you don't think they are accurate then yes you still need to regularly check.

I very much doubt most people check their tyre pressures, fluid levels, lights etc at all.

My third-party system, and my dad's OEM system (2017/18 car), both report the actual pressures (and temperatures) of the four tyres.
The only problem is that the sensors don't wake up and transmit, until the wheel turns. So a visual check before entering the car, is still advisable.
Last week my dad drove out of the gateway before the system alerted to a front/NS tyre pressure of 0psi! £140 down due to a small pointed stone pierced the rubber on a <8000miles tyre

If you do have a OEM system with one faulty sensor, I presume you can leave that wheel at home and present to the MOT with the sensorless spare fitted?

Does that mean a vehicle presented with its proper space-saver spare fitted, cannot be passed?

Why would you knowingly want to find a way around the rules/system. The easy option is to just get it fixed.
