Tyrepal sensors

[POH]

Hi how do you stop the sensor? leaking air, n/s/f has been losing a bit of air from 5.5 bar to 4.7 bar according the the display , was also thinking of removing all of them ,what do the forum think yes or no .

We have Tyrepal sensors on the toad with the monitor on the MH’s dashboard, and signal repeater in the back. We didn’t like the possibility of towing the car with a soft or flat tyre. Unfortunately Tyrepal doesn’t seem to offer a system that will cover both the MH and toad, you have to buy two separate systems and have two monitors on the MH’s dashboard.

We use the tc215 (I think that's the version number) as we have our 6 wheels for the motorhome and then 2 wheels for the trailer on one system

Update, went to local tyre depot to have the wheel checked found it was the valve leaking , it seems it has corroded a bit at the bottom where the seal is they put some sealer on it and refitted seems ok ATM but now on the search for 4 new ones so if anyone knows of a good one please let me know , as for the sensors I will change the o rings to be on the safe side , possibly when I get the new valves .

Are the fleabay ones as good as tyrepal?
I don't know much about them until now, but looks an essential but of kit

I got a kit from Amazon
I never had my brain in gear when ordering. It did not work with the high tyre pressures of the van
Luckily it was Amazon as they had an easy returns policy
Very few of the kits on Amazon or Ebay do high pressures
Tyrepal are more expensive but work on these pressures

My Brother has them on his lorries - 14 tyres.

I had one leaking, the valve inner had loosened so keep a valve key in my toolbox now

Phone tyrepal and get some replacement seals, mine did the same but the seals cured my problem.

We have had tyre pal fitted for nearly three years now and pressure-wise they have been excellent. However, of late, the alarm repeatedly goes off due to a small difference in temperature between the four wheels (3 - 4 degrees) when driving in England.
I have been unable to adjust the parameters of this as temperature is a factory preset - very annoying!

I have a set of 7 on my tag axle van. Always been superb. They warned me twice now of a sticking front brake calliper. Both got immediately replaced and the temperatures returned to normal. Never had a problem with pressure loss from them.
I also have a set of 4 on my car.

 

[poisondwarf]

I have a set of tyrepal in my cupboard which I used on my previous van. The current van based on 2022 Fiat Ducato has tyre sensors built in so I haven't bothered fitting the Tyrepal. If I did fit it would it affect the built in system? Also have another set for another car but the threads on the valves don't seem to match very well so a pain to fit the sensors without loosing all the air I just pumped in!

Good question, and unfortunately i dont know the answer.

It might be the case that the tyrepal system is more accurate and sensitive than the built in system?

Have you tried replacing the sensor batteries?

 

[Purrfecttune]

Yep!

No.

If you want a set of Chinese fleabay ones, with box and instructions, then drop we a line, yours for £20.
I never managed to get them to work properly.

Bought a Tyrepal set at the NCC show (think for £60 for 5 tyres), a bit of a faff to get the numbers correct, but they have already paid for themselves by finding a slow puncture that would have caused a 3 day layover.

Tyre pal everytime for me, if you look around they do offer a discount code, think caravan club maybe one of the places to find it.

There is a Fun discount I think it's 20%

 

[h8ten]

I had a cheapish set, probably Chinese, on a previous car and I was alerted to a puncture before I felt it. What I did notice was that the valves suffered from galvanic corrosion and I needed a set of mole grips to remove the sensors, they had been put on hand tight. I'm going to use silicone grease when I fit a new set to the van.

As often mentioned we are big fans of TyrePal & have had it fitted to both our car & motorhome for many years which has saved us once, so far, alerting earlier than the factory fitted TPMS Now they don't sell direct our Fun discount no longer applies but CAMC members can still buy at discounted rates through the Prima run website https://shop.caravanclub.co.uk/category/tyrepal

So I take it that the Tyre Pal system didn't interfere with the factory fitted TPMS?

No.
As far as I know most factory fitted TPMS use calculations based on rotation speed of the wheel. They use the same sensors used by traction control (magnets in the bearings and sensors) - basically measuring diameter based on rotation speed of the wheel and compare with speed of the vehicle.
.….at least I think that’s how they work. That’s why you can move wheels around and the factory fitted TPMS doesn’t know.

Correct. The cheap way vehicle manufacturers add TPMS is by using the ABS wheel rotation sensors on each hub. A low pressure tyre has an effectively smaller diameter so will rotate faster.

No - no problem

Thanks for the confirmation - I just guessed this is how they do it (couldn‘t see how else they could do it).

 

[h8ten]

On my car, the TPMS readings are run off the valves. If you move the wheels the car will relearn the new positions within a few hundred yards.

Some clever tech there. Wonder how they do it

I can only assume they are individually coded or a sensor picks up the physically nearest one (in case of swapping out due to battery failure) but the car is over 10 years old, so not new tech.

Thanks for that, I do appreciate your comments

On my Vito van, (also part time stealth camper) my TPMS readings are also run off special valves.

I only found this out when I had to replace a faulty valve unit. The OEM part alone cost £65.00.

They can be purchased cheaper from non OEM suppliers, but I didn't fancy taking the chance that a non original part might not work properly.

 

[TeamBandS]

Can I do a small thread hijack and ask if the solar monitor unit charges well enough on the dash and if the unit can be switch off when not being use?

Thanks

Yes to both.

 

[A S R]

Never had to charge mine once in years of service.

Just been on the tyre pal web site and they offer discounts the the 2 big clubs in the UK but say that if any other organisation wish to apply for a discount they can contact their sales at sales@tyrepal.co.uk.

Would Jim consider doing this, especially as members are providing excellent feedback on this product?
