TPM

I had no idea the car had this fitted till i wanted to drop the pressures for snow driving a month or so back and ended up with a warning for all 4 tyres being low on pressure. Rolling Eyes
Does anyone know if i can reprogram the system for the lower pressures or disable this system all together and fit regular valves? Ive a feeling im going to hate TPM Rolling Eyes .....i like slightly lower pressures than those recommended by the factory.
Or have i missed something and being a donut? Neutral

Just leave the tyres the correct pressure. Dropping the pressure makes no difference to grip in snow anyway. If you're loosing so much traction, you can't make progress, you have the wrong tyres. Hyundai Ioniq 5 Ultimate. The family car.

Think you'll find TPMS is a legal requirement on all vehicles after November 2014. Not having it in a post-2014 vehicle could be an MOT fail.

As previous reply indicated leave at recommended pressure, if you're not getting traction you've probably got the wrong tyres on

The tyres are fairly new continental cross contacts on the 19" rims. The recommended pressure is 35 psi.
On snow off road, they just feel a bit too hard. They also feel a bit too hard for regular driving on tarmac for me. I dropped them to 32 psi to start with but it threw its toys around and gave the warning ⚠️
I realise the manfacturer has to set them to a safe pressure to cover all conditions, but its annoying not being allowed to adjust them because of nanny state.
The point is i want to have control over my tyre pressures and it seems i cant, without annoying warnings.

The recommended tyre pressure for the Freelander is 32 PSI all round, at least it is on my 17" wheels.
The TPMS can be calibrated to allow the tyres to be whatever is correct. Instructions on how to do this is in the owner's handbook. Hyundai Ioniq 5 Ultimate. The family car.

Nodge Please can you tell me what page recalibration of TPMS is on. I can't find it in MY2015 Handbook.
It just seems to say that (for me - 19" 35PSI) lowering tyre pressure will affect the handling and increase tyre wear.

Owner's Handbook page 176:

'Tyre pressure can be adjusted to compensate before the start of the journey. Alternatively, tyre pressures can be adjusted when the erea of lower ambient temperature is reached.

In this situation, the vehicle must be left in the ambient local temperature for at least one hour before pressure is adjusted.'

If the vehicle requires TPMS for MOT then the failure criteria is a fault in the system, a warning lamp on indicating low pressure or to check the tyre pressures is not a fault and does not fail. BUT if you were to remove the TPMS valves, then this WOULD cause a fault code to be recorded and the corresponding message to be displayed and this would be an MOT failure. On a final point it might be worth getting your tyre pressures measured and set cold with a calibrated guage, as most warning messages are not displayed until the tyre pressure is 5 or 6 psi below the recommended pressure. Certainly 3 psi below the recommended pressure would not put the warning message on.

I had a discussion with my son yesterday about tyre pressure gauges. I have always used the old sort where the cylinder pops up with the gradations on side rather than a dial meter as I was always told that the meter sort were inaccurate. He had read the opposite. I then got two of the "old" type and they they both read to within 1 psi of each other, the meter in my electric tyre pump was different again. So what sort do you people rely on? 3 x FL1 2 manual + 1 auto

My first query to the forum was about TPMS and fitting new valves to a spare I already had.

I got an excellent forum answer and fitted the TPMS valve with no troubles.

https://www.freel2.com/forum/topic30058.html?highlight=tpms

As normal a good search of the forum will find a similar problem and hopefully an answer.

Try TPMS

I have 2, more or less cheap electronic gauges & the dial on the ARB inflator. I under inflate the tyres by about 2 psi to match the cheap electronic gauges. My TPMS is within 1psi of the cheap gauges.

I had the opportunity in the outback getting back on the hardtop & airing up & at the same time as a camping neighbour with truck tyres. When I had finished I offered to air up is other tyres as 3 compressors as somewhat quicker than 1!

He happened to have a professional gauge with large dial that had recently been calibrated. My cheap gauges were within 1 psi of the calibrated gauge.

Just get the tyres within reason. If you have TPMS showing pressure, the pressure changes a fair bit with hot & cold weather. If the sun is on some tyres for half an hour they will be about 3psi higher than the shadow side.

After diving an hour tyres will be about 3psi higher.

I rely on a good mechanical gauge... that *should* be more accurate (and precise) out of the box than cheaper alternatives... but even so age, use, or getting dropped can affect those too. I've heard that a good digital gauge should be more accurate and consistent because it doesn't have mechanicals which are subject to change or damage.

The only way top know for sure is to have a good gauge and check it periodically against a known standard, large garages or any racing outfit should have those. My work-around is I have several cheap gauges, and I know how much they vary from the good one. I set the pressure with a stick gauge built into the hose fitting, and then check it with my good one. My motorcycle has Fobo TPMS installed, that way I can check it from my phone every time before I ride without losing 0.5 psi in the process. The Fobo TPMS matches my good gauge exactly.

Motorcycles need pretty accurate pressure. Our LR2's need very CONSISTENT pressure (and tire wear) across all four wheels to avoid stressing our already weak gear-boxes with slightly different RPM's.

You can also calibrate your gauges with a long tube of water if you have access to a tall structure to hang it from. Very accurate once temp is accounted for. You can do it with a much shorter hose (3 feet) if you don't mind fooling with liquid mercury.
