I have been pretty quiet on this one and testing a range of pressures.

I have finally settled on this one:  28psi / 1.93 to 2 bar.   (For general road use)

You are going to find that you will wear the centre of your tread at an accelerated rate at that pressure. As we have all said start at the standard 26psi and go lower.

2 bar is way too high. 1.8 bar is the manufacturer's recommendation. The bigger the tyre, the lower the pressure. I wouldn't go higher than 1.7 bar on 215/75R15.  I run 1.4 bar on my 235/75R15's.

As said many times. 1.6 to 1.7 bar.

If its a Gen 4 you can't go lower as the dash lights up like a Christmas tree and stops it telling you anything else.

Unless there is a way to adjust the TPMS settings or disable them.

I was under the impression that the emulator modules were for doing that, delete the wheel sensors and set the emulator then regularly check the tyre pressure manually like a normal person?

Yes, you remove the sensors and use an emulator module to fake the pressure readings and manually administer the pressures yourself

I have those tyres on my Jimny for 6 months and this is what i found that works best:

1.8 bar - road use
1.2 bar - normal offroad (low amount of rocks or mud)
1.0 bar - offroad with lots of rocks or lots of lots of mud

But i didn't tested them with sand yet. Probably i would go even lower, 0.7 or 0.8 bar maybe.

Thanks.

I'm not familiar with the emulator modules. Are the generic or specific to a model/marque?

As they emulate the sensors, they are specific to the sensor/receiver set-up which in the case of Suzuki is from Continental Tyres. Therefore the emulator emulates the Continental  Sensors.

I have one here on loan for a member (no, I have not forgotten I have to return it, David). It is from IronGates.

 

 

Here you can see it transmitting random sensor information.

So does the use of this emulator require the TPMS sensors to be removed from the wheels or will it override the existing sensor signals ?

Sensors have to be removed otherwise the Jimny system has eight "sensors" to choose from when learning the sensors (which it does every time it has been stopped for more than 20 minutes)
