Interesting
..and I just did a bit of googling
?
I read the study.? The world has changed a lot since 2009.? I also found some “derogatory” references and “comparisons” to four systems by someone in 2009
..the PDF is out there, but you can’t, or at least I can’t, locate him.? It says the Tyron is “US Based” and does a good job of trashing PressurePro.
?
Chuck Thatcher, whom I fully respect, also in early 2010 taught a course at LD on bands and such.? In the course, according to several folks that posted on FMCA, he said that PressurePro was in financial trouble and to order a set of new sensors or keep a spare set as they would not be in business at the end of the year.
?
That was refuted and there was a lot of “internet squabbling”.? What is interesting is that the owner of Tyron USA dropped out and Chuck bought the franchise
.as Fred says, his goal of to become a Government Supplier.? Wonder WHY everyone wants to be a GOVERNMENT supplier
?
The Booze Allen study is interesting to read
.sort of like the physics experiments that we did in college.? I also used to purchase consulting services and Booze was on my list of folks to send “Requests for Quotation” to.? They have a great reputation, but I was never able to justify their fees and obtained what I thought was the same services with the same thoroughness and validity for less than 10% of their quotes
.
?
So, wonder WHAT the 2009 study cost the taxpayer
.and the fact that most of the vendors or perhaps I missed that, are no longer available, what value is it how.
?
I STILL would be interested to know the relationship (and history) of HCI and Tyron.? Since you have done the research so far, perhaps you can contact them and fill in the gaps
..HOW are the Tyron and TireGuard systems related and what is the history
.
?
Again, your assessment of Doran matches quite a bit of OTHER opinions on other boards.? Personally, aside from the reliability issues of the Doran, it had some pretty good features.? In my spare time this past spring, I started using Bill G’s formulas, after I corrected them, and then resurrected some of my old thermo.? I figured out that the PressurePro does have a couple of shortcomings in the SET-UP.?
?
I don’t know HOW the TireGuard works, but what is needed is to have the tires inflated to a KNOWN standard WHEN you head out.? That is typically stated as X PSI @ Y temp.?
?
Then, you can accurately calculate the “alarm” points.? If you vary too much from the “cold inflation pressure” and use the PressurePro “preset” alarm percentages, you can actually overheat the tires.
?
NOW, with my NEW tires, the Bridgestones, that is NOT an issue as they run much lower than the Goodyears
.in other words, they heat up LESS.
?
I made up some Excel tables and did some experimentation and also pulled the data and formulas used in the SmartTire manual.? That was the MOST professional discussion and explanation.? Seems like this is a very miniscule thing and generally speaking, nobody is interested.
?
I concluded that as long as I inflated my tires to the 65 degree pressures that I wanted and rarely got down into the low morning temps in the 30’s that I did not need to “TOP THEM OFF” and recalibrate.? NOW, with your sensors, the flow through caps would be great
if you were in the extremes
.most folks say that there is enough safety factor not to worry about it
my point and my concern is that if you start off at an incorrect pressure and then the tire starts to heat up, you might go well into the danger zone before you hit some arbitrary limit.
?
That is why the SmarTire INTERNAL sensor (or perhaps the Tire SafeGuard/Tyron) is the BEST protection.? If the internal temp of the tire starts to hit 180 or so, then you need to KNOW that
.regardless of the pressure
..and figure out WHAT is going on.? The “external” sensor temp, just based on simple thermo conductivity, is just an “indicator” and not really an accurate number.? The Pressure values are the ones to consider.
?
Let us know if you pursue this and what you find out

Tom,
?
My guess would be that Tyron has leased the right to sell the Tire SafeGuard TPMS under their label much like others do. Two that come to mind are the Tire Tracker and the Tire Minder systems which are identical systems.
?
HCI has been around since 1989 and they have been in the TPMS business since the mid-90’s.
?
http://www.tiresafeguard.com/about_us.htm
?
There is a world of information on the Tire SafeGuard website. One just needs to go through it all and determine whether this system will work for them. I spent a lot of time on their web site and read through a lengthy document detailing a case study of three different TPMS’s used on Fleet Vehicles for the case study. This study was done back in July of 2009 at least that’s when the report was written.
?
http://www.fmcsa.dot.gov/facts-research/research-technology/report/FMCSA-PSV-09-001_%20BrakeTireSensors.pdf
?
All TPMS systems will have some problems with them such as false signals, etc. The HCI TPMS (aka Tire SafeGuard) had the least percentage of false signals. That was only one of the factors that swayed me to their system. There were many other reasons.
?
I feel confident that I made the right choice and have used it 4-5 times since purchasing it back in January of this year.
?
The Doran RV360 turned out to be the worst investment that I had made into a TPMS system and others have had similar results. Check on the iRV2.com website. I did NOT want to go through that agony again so I took my time and did a thorough research BEFORE making another decision about which TPMS system to purchase.

Richard,?
Since you are the “Film” Doctor
..look at the 2.2 Monitor – H on page three of your 4 page link.? That photo looked familiar
..This is either the Tyron system or an exact knock off
.In this photo, it looks like they covered up the Tyron Logo with a cheap label or Photoshopped it.?
Click on the link that I provided
..HMMM
..this appears to be the photo or the artwork at Tire SafeGuard TPMS “ripped off”.?
I will let folks decide
..but when the Doran RV360 came out, I THINK it was marketed by PressurePro’s largest distributor and there was a court case.? Doran actually USED exact cut and paste wording from the PressurePro manual.?
I read both manuals prior to my purchase.? I then found out about all the “Divorce” and then it hit me
..I went back to the Doran manual and sure enough, there was a passage that was a cut and paste.? I had talked to Doug McMeen
..he said it was almost verbatim to begin with.? I sent him the passage and he said he would “take it from there”?
The units are the SAME
.now isn’t THAT interesting
..sort of Chicken and Egg
.?
Wonder what Chuck Thatcher would have to say about this
.Maybe when he bought the US Tyron distributorship, he did not get the TPMS or chose NOT to
.?
Also wonder if the same Chinese factory that is producing the Tire SafeGuard is also the original Tyron one and if the Tyron is NOT being marketed in the US, if they are offering it
.?
This ALSO looks exactly like what I read on the original SmarTire site
..their old RV manual was the best info out there and they also had REAL engineers and a REAL product development department
.NOW, you go to the Chinese and they sell you a SYSTEM that THEY have KNOCKED OFF
.there is a Canadian and a US Version of one system with replaceable batteries
.can’t remember which one
.?
What is somewhat disheartening is that most of the companies are just store fronts for a Chinese electronic company.? ?
I will get off my soap box, but at least PressurePro and SmartTire actually have folks that understand what they are selling and have done some testing and development work
.?
Maybe the others have too
.Don’t know
.?
Look at the photos yourself and give us your professional opinion.?
Fred,?
I will leave it to you to contact Chuck

Joe & Fred,
Actually there is one. And Fred, you just bought yours from this very same
company.
Tire SafeGuard TPMS.
http://www.tiresafeguard.com/
Unless they have recently made some changes in their product lines I believe
they still offer two types of Internal Sensors.
http://www.tiresafeguard.com/pdf/TSG-TPMS-Info.pdf
Fred purchased the external sensors like I have except I wanted all CAP
sensors whereas Fred purchased Flow-Through sensors for his coach and CAP
sensors for his car.
