Hi Don,
Your most likely right, but for me these things are more trouble than worth I feel.
Agree on temp change does change the actual psi, why I am going to leave them alone for a week or so, and then decide if a go/nogo.
Am headed to HWH and Custer SD next weekend, so I will have little joy playing psi games with goofy PP jokes.
Trust all is well, my artery / bypass is still a joy.

Thanks

Dave, your Marine Corp tolerance is beginning to show.

Hmm... neither Steve nor I were in the Corps, but our tolerance isn't much different than Dave's on this one

It took several tries to get one of the coach sensors to finally seal; we still have not solved one on the car. Not a terribly robust design.

So far our initial impressions over the 2 months of ownership are that it's a high-end tire gauge that excels at letting you know when it's released enough air from one or more tires that you need to break out the compressor

Had the TST internal sensors been readily available when we put tires on this spring, I do believe we would have gone that route instead. We almost bought one of the TST external sensor systems, but went with PP instead because of the lighter sensor weight. Next tire time it will likely be a different story.

Have not looked at my display in two days, now scared to plug it into the power and fire it up and hear the chirping, if it chirps, it is a goner. I do not tolorate junk nor bad designed crap. IF this thing give any more issues, yup, goner it is. NO JOY with it, maybe someone is dying to have it at a reduced price ? 10 sensors 1.5 yr old, been removed for 8 months prior to this last gasp.

We purchased a Hawkshead System 2 years ago for our previous motorhome. Moved it to this one and have only had a couple false alarm sensor issues, none of which was on the toad which is what we really wanted to monitor in the first place. Never had any loss of tire pressure from it.

It has replacable batteries and the sensors are some of the lightest in the industry. (or were at the time we bought it). But, if I were looking today I would strongly consider TST.

We do not unplug our tire pressure monitor display. We keep it powered all the time so we can be aware of tire problems or have an instant alarm if someone unscrews a sensor.

ACID Test today, I have new seals, all tires appear to be holding air (so far), had to replace 1 on the toad RF, now appears to be holding, so I will hook up toad with the ATV and aim westerly this PM. Feel the need for the CO2 bottle just inncase the alarm goes off. If so, chances are very slim the PP will be active on coach and toad when I get home.
Barry, agree on keep it fired up, good alarm if one is removed of leads down.
Very little faith in these (poorly engineered) PP devices.
You would think a engineer would not have such a problem designing a leak proof sensor ?

I bought a used (probably just sitting in the box for years) PP set a couple of months ago. I sent the senders to PP for replacements since the old batteries were long gone. The new units have red seals in them, the old ones were black. The FT has been just sitting unused for a month, and all tire pressures were holding fine until this week, when one of the tires dropped 10psi. I guess I'll top off the air and retest.

Interesting - we just got a packet of replacement seals direct from PP a little over a week ago and they are all black. Replacing the seal on our leaking toad sensor didn't solve the problem, either.

It seems that more than 50% of the posters have an issue with the pressure pros. I know some of you swear by them but to me, I think they are a accident waiting to happen. I have put on 300K miles and have not used one. I have over a million miles on my various trucks over the years and do not have it on there either. I have heard, you can not see your toad tires and you do not want a blow out. Surely, I do not want any tire to go down but I look them over every stop I make. I make sure they are full when I leave on a trip. I guess I am willing to risk the road hazard and not add an extra one. I think that the proper type is going to be inside the tire not on the stem. This has been an interesting discussion to follow though and one which has cemented my decision not to use them.

As I have posted in the past, we have used PP for about 6 years on both our FT and the Airstream travel trailer we owned. I have only had one sensor that leaked. I now have 10 sensors running between our FT and the toad. No problems. Could it be that there is something else going on? For example, could the valve stems be different in some way that can lead to leaks?

Well, Duh! ;o)

Folks like me, who have used PP for years now and have had no problem with them don't have a complaint to post about. (Somehow, this strangely seems to me to be the corollary to, "It's always in the last place you look." Of course! Why would you continue to look once you found it? A recent New Yorker cartoon about those searching for the Higgs boson had "It's always in the last place you look." as its caption ;o)

I recently thought I had a problem with 1 of my 6 PP's. But it turns out the problem was the valve stem was "short" for some reason and the PP did not depress it and consequently could not read the tire pressure.

The real mystery to me is, "Why do some folks have problems and others do not." Something is obviously going on. And I have removed my PP's and aired up, etc, and put them back on. I don't think it's any special skill I have. Strange....

The valve stem has two possible leak points: at its connection to the rim and to its PP. I wonder if any pressure losses attributed to PP are actually losses at the rim leak point.

But, based on the problems others have had, at stops I do my due diligence and take my trusty tire bat out from behind my seat and bang on tires. That might be all we need for steering tires.

In addition, I rarely drive faster than 62 mph.

Had a steer tire on toad blow at night At 70 mph behind my old 89 GV. Bad camera, no clue what was going on till some one pulled alongside and flagged me down. Might of helped, might not. Rim was still good, got two new front tires, still never. BOught PP.

My conclusion, not worth cost and aggravation, one event in 7 years.

Your mileage may vary...........

Paul,
A great point, Have to mention my PP worked well on the toad for a year, then the LF started leaking for no appearant reason.
As for the coach, the front tires seemed to not have an issue, the drive axle, all four have had issues since new. The brillant part, remove the PP and no more leaks, checked for seating of the core's, talked to PP, they informed me that I was clearly too stupid to install the sensors. The most amazing part, after buying the "tool" and 10 new black seals, after redoing all 6 on coach, no problem "YET", as for the toad, the LF needed two different seals to stop its leaking, Clearly due to my being too stupid to do it right.
Now am in Pa, headed to Black Hills, SD, and so far so good.
Many variables, but I still feel PP has their collective head so far up their butt, they feel many of us users are just too stupid, instead of wondering about their QC or design issue.
OF course this is my opinion nearly alone I assume.
Ever wonder why they changed from the black seal to the red seal ? Maybe the head was retracted a lil bit ?

So you installed 9 out of 10 and had no problem with them. And fixed the 1 with new seals.

PP telling you you are too stupid is obviously over the top. I'll have to reconsider being their customer in future.

This happened to me recently when I tried to reserve a site at an RV Park I'd stayed at before. I called two different numbers I found on the web. Both were out of service. I thought they were out of business. I stopped in as I later passed and told the owner of my experience. He said I didn't wait long enough for the call to transfer!

Two of the failures we had when we used TST TPMS were failures at the grommet where the stem attached to the wheel. I think the added weight of the sensor caused the stem to move enough to cause leaks at the grommet.

We had a steer tire that would lose a bit of pressure as we drove. It would hold air while parked. We had a drive tire that when completely flat in short period of time. I discovered it before any obvious damage was done. In both cases, the flats were fixed by replacing the stem grommets. No other damages or punctures were found.

Would you beleive, I am at a Cracker Barrel in Champain Il. and the PP are
still working as advertized, guess I need to kiss all 10 tires for continued luck.
Still no warm fuzzies yet, just nerves shaking.

Is it possible to use external type sensors on a Crossfire system? That might be a way to avoid problems with mounting weights on end of valve stems.

I have the crossfire system but am having a problem with the PP sensor not holding the air. Both tires go almost flat overnight. OK on one set of dualies not good on the other side. Haven't resolved the issue as yet as I have bigger fish to fry, ie. front bulkhead repair not complete yet.

Roland, I can say with experience, that a new seal did not cure one issue, but the second new seal did, so my opinion is, all seals are not created equal.
Of course it can be blamed on hundreds of items too.

For me, I am hooked up at HWH, Moscow, Ia, was scheduled for Wed & Thurs, but they are slow and will get me in the shop in the AM (Tuesday) so happy!.

Met a couple here at HWH with a 42' Mandaly single axle, couple non HWH slides and hydraulic levelers, the levelers is why they are here.

Still the PP units are still quiet, all 10 sensors do not have 100% communication all the time, but guess enough to satisfy its brain.
Best location for me is sitting on drivers glass window frame, clamped on with the Nuvi mounted on same window, just luck, seems the best location.

If this keeps up, I might get into Custer early.

One little comment, my Blue OX Keyed pins (On toad hitch) were in need of a pry bar to get one off, the key turned fine, felt good, just would not come off the pin without help from a large screwdriver. I used WD-40 washed them out and cleaned up nice. Hope that is all that is needed.

According to PP there is no difference between the red and black seal. I tried SOB and had an issue with their seals while initially setting up the unit (two bad seals out of eight). Sent it back and stuck with PP. Guess sealing a tire valve stem is "high tech).

Roland,
Agree on the high tach, but everything is high tech if you have no clue as to how it works or should work.
My understanding,, when a company puts a product on the market, I would guess they have worked out any & all weakness issues, if for no other reason for customer satisfaction. But now I feel such is not a biggie for PP.
Must say so far on this trip, I have had no issues as of yet, but prior to now, I had massive issues, only when I purchased the "kit" with a modified nut driver and 10 seals, that finally and after replacing one new seal, that no more leaks YET.
Gotta say when they work, it is a good feeling to know the tire pressure, but right up to that time, PP was not and still is not a highly regarded product.

Interesting discussion. I have a factory pressure monitoring system on my Mercury (think it was federally-mandated) that has worked FB since we bought the car in 2008, more than 70,000 miles ago. A couple of times it has alerted me to low pressures, and has been correct each time. One of the old guys at the tire shop said that all of those ***** things ought to be thrown away and regular valve stems installed. The was while he was removing the nail that the monitoring system alerted me to.

Between now and when we get our full-time coach I'll need to read up on these systems.

So far, so good with the PP, after 13 days since it was determined they were not leaking (all 10), I am currently at the Custer Game Lodge Campground and going to depart little later this AM. I am happy to say the PP system is still quiet, have the blinking green heart beat, but no alarms. Sometimes I think it lost the DC voltage but so far all is happy.
I am so happy to report this good news and still wonder why all the leaking issues that PP claims they NEVER had a leaking issue EVER.
Gee I feel like I have been Bullsh$ted, and do not understand why PP takes the bull headed stance instead of working with idiots to solve the issues. Their defense is "Your too stupid" to screw the sensor on.

Story of my life "no one has that problem but you" I have heard that and different versions uncountable times in dealing with product issues both in my career and private life. And yes I had issues with PP, went so far as to purchase a different TPS but the other model was no better, (two inoperative sensors at the get go). Must take a Mechanical Engineer with a PHD to screw a sensor on a valve stem.
