If anyone has these TPMs on thier car or mth be aware that the locknuts which are used to lock them sieze up,mine had been on for 2 year and it took me over 2 hours to release them using a pipe wrench on the valve and a small adjustable spanner on the nut to loosen the nut as the spanner that is with the was useless and damaged the rubber on the valve, i put new batteries in the monitors and put them back minus the lock nuts.
Took the chance nobody tries to steal them
 
Haven’t yet connected mine up. Still in the box, unopened! This followed a thread that included a lot of posts about their failings (as well as their benefits). I’m still undecided. I used to be indecisive but now I’m not so sure. 🙂

had them on old van ,put on new van but got them mixed up ,as Busby says they were forever bleeping ,phone Tyrepal up to see if they could be a fault with then they told me to send them back in box with paperwork and they would recalibrate them which they did for free ,put back on van no more beeps 🤞🤞
 
Threw mine away. Intermittent signals and ate up the battery. Plus, I actually found it more stressful to see how much pressure the tyres had gone up too, when it’s hot and you’re on the M/Way
 
I've had mine on for 2 years without a problem, although the tyre fitting place, despite assurances that they understood about the locking nuts, didn't and lost the protective rubber shields!
What I have found is how much static tyre pressures differ depending on ambient temperature. Had to move the Truck for a Fuel oil delivery a week ago in the cold snap and the dash display was bleeping away showing a 10 psi loss on both fronts (the rears were still within the parameters I had set). Pressures back up to normal in the sun and would have been with a few miles on tarmac as well. I believe the trick is to set at least 8 psi each way for the upper and lower limits which will prevent some of these false alarms.
I firmly believe that anything that gives me notice of impending failure of a tyre, so that I can find a decent refuge, is worth a bit of set up hassle.
 
With some of the externally-attached sensors you can change the battery without removing the sensor from the valve stem.
 
Had our Tyrepal about 3 years with no problems at all. It does make adjusting the tyre pressures a bit of a pain but overall worth it - we lost a tyre to rapid deflation on a Spanish motorway, fortunately OH managed to control us to a safe stop, TPMS would have given prior warning reduced the danger and saved the tyre.

Just changed our tyrepal batteries without taking them off the valve
 
Chucked the locknuts in the bin, they were a pain.

Tyrepal has been faultless for 3 years. Wouldn’t be without it now.

It's a right bu**er though when the sensor is at the bottom of the wheel!:rolleyes:

Yeah I know, just move the van back and forwards to reposition!:rolleyes:
 
Fitted for over 2 years and had to change 1 battery. No issues apart from that. I recommend them.
 
Tried cheap ebay ones, they were crap.
Now have tyrepal and they are good.put a bit of silicon/wd40/spray lube on the valve stem threads too avoid seizing.

Took mine off all together.Managed 40 odd years without them,Had them on a couple of years and they were forever beeping and flashing..BUSBY.

Probably because you hadn't set them up correctly, you need to tweak the standard settings for a Motorhome the tyres increase in temperature more than on a car that they are set up for.
 
Ours are fine, first trip out with them we had a puncture of the motorway north of Rouen. It was on the tag so may well have done serious damage if I hadn't felt it.

Done it for 2 years with no issue, obviously you only lubricate the thread.

Sure you have... however my point was if you not careful "spraying" the threads you MAY end up contaminating the sensor.
As a footnote, I have had Tyrepals fitted for 4yrs now with no added lubrication/spray on threads and have never had sensors or locking nuts seizing on threads.
Just lucky or knowing what I am doing.??😎

Just been to the storage yard and checked all the tyres. I was expecting them to be down a little as I hadn’t checked them since the beginning of December and all were spot on 👍🏻

Then cleaned and polished the wheels and outside cab, most satisfying indeediediddliedumdum 😀👍🏻

Did you move the van so the wheels rotated as I've thought the same driven it a few yards and the pressure changes. It's like it remembers the last reading since the wheels last rotated.

Had too, the compressor lead is only so long, so it’s a juggle shifting the van and car around to make it reach, so moved it again and again. I usually take it for a good run up and down the A21 every few weeks, so the brakes stay clean and shiny and the tyres get to warm up a little.

Had to lower the roof to get it to reach the spare in the car, it’s one of them there space saver tyres and needed pumping up to 60psi. Lots of hassle taking it out, so have it set up to reach the valve in situ.

Lenny HB you are indeed correct... you have to drive a few hundred yards to wake sensors up.!

Had same issue with mine on both my motorhome and off-road vehicle. Smear of copper grease on the valve stem and also between the lock nut and sensor - Cured, no more problems! 😃
