Thanks Steve for adding the 'link'.

Roger, The last time I took the coach for a ride, was only a few weeks ago.  Checked tire pressures thru the TST system and all were fine.  Sounds crazy that I now find ALL of the housings on the 6 sensors cracked and battery caps too.

However, I am moving from the sail loft location i've been in for 6 months, back to st. pete then on to Panama within a week and will deal with the company when I get back near the end of the month.

Just wanted to 'alert' anyone that might have this TST system with the newer flow thru valve monitors, that there seems to be at least a defective batch.  Certainly, mine have failed.

I ordered the internal sensor version on Monday, and UPS says they will deliver them tomorrow. My plan is to have them installed when I get the new tires next week.

David, I'll be interested to get your report on the internal sensor version of the TST after you use it for six months to a year. We tried TST four years ago and put it back in the box after six months. I really like the concept of TPMS, but our experience was not good with the TST we bought nor with the Pressure Pro that came with our current coach. I look forward to a wheel mounted (not stem mounted) TPMS that would handle the coach and the towed vehicle, and allow "normal" use of valve stem caps, tire gauges, and tire fill tools.

It's good to have a fleet of testers reporting to me on a regular basis. :D Thank you, Steve, Michelle, moderators, and other contributors.

I'll be interested in the internal sensors as well.  There is a $50 surcharge at least to get them installed if you can find someone to do it (at least that is what it costs to dismount a wheel, remove the tire, replace a stem, reseat the tire and remout the wheel and torque it to spec.)  My tire place won't do anything with aftermarket TPMS. 

I can replace batteries once a year.  If the sensors are not reliable then the whole thing is just not doing what it is supposed to do and then it isn't worth much.

I still check every tire before departure.  It is a good practice and only takes a couple of minutes.  I painted all of my stem caps yellow.  I got tired of losing them even when they were right in front of me in plain sight.  They just look too much like the gravel.

Keep reporting, I will too.

Six years using Pressure Pro has made us a believer in Pressure Pro. Monitor is powered all the time and in one minute, we check individual tire pressures of motorhome and Jeep every day to get a heads up on tire problems. Comforting to instantly know if we pick up a tire problem while driving. Sensor batteries lasted over 5 years.  Easily worth the cost.

When checking/adjusting tire pressure I place the caps on the wheel for the rears, and on top of one of the decorative lug nut covers for fronts. If they are on the ground, they are indeed likely to disappear unless they are bright yellow.

We bought tires three years ago, so I expect it may be about three years before I would be willing to install wheel mounted TPMS. I will be interested to hear from those using cutting (bleeding?) edge TPMS technologies.

I expect installers will be reluctant to install anything other than the stems and grommets that have been proven effective by years of use.

Gents and Ladies, we are all trying to help one another.
My renewal of an older post was to 'alert' anyone that had bought a TST system about this time last year.  I can only surmise, that there is a design flaw early on,,(thin casting-wrong chemistry of plastic...etc) that had quickly been addressed!

The concept seems fine, but as a 'newbie' I read all I could before buying.  I bought 'before' tires being replaced...maybe a mistake but FT ended up doing both.  They did well/no problem.  This issue is not theirs, but totally...TOTALLY a product Failure and that is why I posted my 'alert'.

I feel sure the company will take care of things as early productions often have a glitch or two.

I have loved the security of seeing numbers....but have noticed the TST system aboard my coach reads 4 lbs. low..    Tire gauges show 104 when their system shows 100.  Make note or check for yourself.

Have learned a lot from all of you and want to thank you all, once again.  Hope this little alert helps someone check for road safety.

I just might go to internal sensors and have all the tires broken down to insert.  In the end...it is all about safety and unless TST comes thru with paragraphs of explanations, I will go to the internal sensors or change Manufacturers... I'll let ya'll know.

We find all truck tire shops are hard to manage when dismounting, mounting, balancing & remounting. They assign multiple techs, don't listen and do it their way. Find it hard to see how they will do the right thing to mount internal TPMS sensors. And once all things are put together, any problems will be a pain to resolve, not mentioning battery replacements.  But I think internal sensors are a good idea and our Jeeps have them, where they are mounted on the inside of the valve stem. (we find Pressure Pro no-hassle)

Barry/Cindy, I can agree with all you said.  Problems with any portion of an 'installation' of........anything! ....can because of the quality/mindset/attention span etc. of an employee, can either 'make your day or ruin your road experience down the road'.

ORIGINALLY.. i did not like the concept of installing these devises 'inside' the rim of the tire..  but

Internal sensors are not as subject to the vibrations at the end of a valve stem.. My sensors have worn the Alcoa surface enough on the stem ends/where the sensor 'hits'...  I have tried on my short usage,  to insert a foam tape between each.  (rim and sensor)...but they disapprear.

I believe, that if, IF... my problem was seriously 'noteworthy', then there would be a ton of folks on this, commenting now...

This tells me, happily, I might be the only one. 

Anyway..............for anyone out there that has the TST system...I'd suggest to look real carefully  at your tire sensors.

stay well, ron

I think herein lays the biggest problem.  I have ordered a set of 10 of the 507 pass thru sensors.  Called TSTTruck and told them what I was doing, new tires, new stems and new sensors.  Told them what size wheels I have and wanted assistance with what size stems to order.  They did not have a clue and referred me to a dealer.  Talked to a lady at that dealership and she didn't have a clue either.  By the way, my son is a dealer, hopefully I can get him trained right.  I understand the problem with the sensors rubbing on the wheel - which should not be happening.  The stems are to long or not properly lined up.  That is something the tire jockys should be watching for, but they don't have a clue of what is happening, and probably don't care.  The good thing is that TSTTruck has a great customer service and appears to be willing to go the length from what I have read on other forums.

I agree with the comments on TST customer service - the best. However, their product seems to be poorly engineered. Maybe it's their QA. Had the 510 system on my travel trailer for 3 years - it worked well. Put a 507 system on Phaeton 36 and toad, did 5 long trips and had problems on every trip. Failed or leaking sensors, 3 different monitors failed, etc. I have to admit that TST did refund my money in full.

Does anyone have experience with TireMinder or TireTracker?

One of our inside dual valve stem extender with Pressure Pro sensor also was too close to aluminum wheel and wore sensor and wheel. I put a short piece of tight fitting thick clear vinyl hose over Pressure Pro sensor and that took care of wear. Has not fallen off in several years of use. Not a deal breaker for me as I think Pressure Pro is the better choice for us. So you are not the only one with the wear problem.

We haven't had any wear on our coach wheels, front or back, due partially to the arrangement of our extenders on the rear duals. See attached pic, which was taken before I installed the Pressure Pros on these new Toyos last week.  However, we have had wear (indentations) on the aluminum wheels on our toad, the Honda Accord.  I adopted Barry and Cindy's use of clear plastic hose (about 1" ID), cut into 1/2-3/4" rings that fit tightly around each sensor.  We did that about a year ago and have had no wear since then and the rings have not budged. :)  I installed the new O-ring valve seals on all 10 PP's and haven't had a single leak in the past week.

Because this issue might have been a 'safety issue' consideration for others presently driving, I decided to address this issue of my surprising...cracked TST wheel senders, pronto.  I contacted the company and was addressed very courteously.  Because I was going to be out of the country for awhile, I asked them to put the issue on hold until my return.  they did.  I returned, shipped the sensors back/ordered 4 extra+a Repeater.
NOTE:  the representative, Abby, confirmed they DID have a bad batch and would certainly replace the defective ones.

We did this quickly when I returned to the U.S.  My package containing 6 new sensors and...............4 more I bought for my Toad + a Repeater(at my cost), were delivered today.

Seems like a darn good company, trying to do it right!  Sensors looked to me and maybe....a tad beefier + date stamped.

Installed TST TPMS about 1100 miles back.  8 coach flow thru sensors and 4 non-flow thru for the toad.  Easy setup and somewhat easy install.  Seems to work very well and no problems so far.  Seems to be accurate with all sensor readings consistently 2 psi lower than my Milton gauge. I'm a happy customer!
