Hi everyone!

New to the MX-30 since 3 weeks and very pleased with ours, but the active tire pressure monitoring system (TPMS) is really annoying. I somehow had assumed that the car would be similar to the Mazda 6 with the passive system operating via the ABS sensors.
The tire dealer did not inform me that I would need sensors on the 2nd rims when buying winter tires. So now I get alerts every time I start the car (at least the INFO button makes the big notification disappear during the drive).
Apparently there is no way to disable this alert, apart from buying sensors and configuring them? And every time when switching tires back, I need to have them configured again?:rolleyes:
I know there are off brand sensors fitting directly on valve caps available operating on the same frequency. Does anyone know if they could be successfully configured by a reasonably tech-savvy person himself?

Thanks in advance, Seb

Seb, see this from the mazda mx30 user manual re tpms registration on new wheels/tyres

When changing tyres and wheels
When changing the tyres or wheels
(such as installing winter tyres), it will
be necessary to register the ID signal
code of the tyre pressure sensor to the
TPMS.
Have an expert repairer (we
recommend an Authorised Mazda
Repairer) do the registration or register
the ID signal codes of the tyre pressure
sensors using the following procedure.
NOTE
The tyre pressure sensors on each
wheel have a unique ID signal code.
For the TPMS to operate correctly, the
ID signal codes of the tyre pressure
sensors need to be registered to the
system.
1. Wait more than 19 minutes after
changing a tyre or wheel.
2. After more than 19 minutes have
passed, drive the vehicle at a speed
of about 25 km/h (16 mph) or
faster for 3 minutes or longer. While
driving, the ID signal codes of the
tyre pressure sensors are
automatically registered.
NOTE
If you drive the vehicle within 19
minutes of changing a tyre or wheel,
the TPMS warning light will flash
because the ID signal codes for the
tyre pressure sensors were not
registered. In this case, stop the vehicle
and register the ID signal codes of the
tyre pressure sensors following the
procedure.

Now I have to assume this is for mazda tpms sensors so if you buy aftermarket ones might the ID code not match the mazda code configuration? Apologies if this is not helpful but it's seems its not a technical procedure as such needing the brainpower of a wizard but simple install and set up...assuming the sensor ids match what mazda tpms expects.

It was not entirely clear if the need to reconfigure (at the Mazda service) would arise every spring and autumn even if I buy Mazda sensors. Hence my interest in aftermarket ones without the obvious reason to unmount the tires from the rims. I will likely wait for March when I get the summer tires under the car...

At least you don't need mazda to reconfigure as they would just do the same as I have stated above! And yes if you have proper mazda sensors on both sets each time you change it seems you would have to reregister each time. The cx30 forum asked the same question and the answer there was fit mazda sensors (or oem compatible) to each set of wheels! Sorry I cannot be more helpful.

There is only a need for configuring the sensors one time and the first time the car detects them they will be stored in the system, so Your car will know them next time you change to winter tyres

In my case I use sensors from Mazda, and off cause they are often same quality as the good OEM sensors, except you dont have to configure them for your car. Mazda also buys their sensors by several of the main OEM vendors. Try to get a good deal at your locale dealer. I was able to get the "original" Mazda sensors for a lower price than the OEM sensors and saved programming/configuration of the sensors.

I have never reconfigured my sensors on our CX-5 when changing between winter and summer tires.
