Tpms?

[Adventure.AS]

It looks is like a tow vehicle and travel trailer to me. When you are driving you aren’t looking at the display often. The tire that is currently being displayed links on the monitor and you can observe the pressure and temperature for that tire. It would take too much of your attention to watch the monitor for the complete cycle of your four (or in my case five) tires. You are mainly listening for an alarm. It is handy to check all the tires before starting each day.

Opinions?
One, the Dill monitor is hard to read?

Dill is the system I have. Monitor not hard to read at all. Work flawlessly. Had Tire minder 1st. Kept having problems so I returned it and got Dill

The problem with internal sensors is that you have to remove the tires to change the battery. That might not be an issue if you change the tires every five years. BTW I believe that TST makes an internal system too.

TST monitors:
B&W and color. I can't un-see a truck with a trailer.
In the color version, the trailers tires are all on the front half.
(Yes, I know, the tires only show with the sensors)
Don't you see a semi tractor with mirrors and a trailer?

But, I've concluded that the TPMS sellers all buy their monitors from the same factory in China, so changing the display is not an option.

I like the fact that the tst monitor charge lasts for days before u have to plug it in. The system works just fine as most others do, I’m sure.

Change batteries when you change tires. I think occasional use tires age out after 5 years anyway.

I have the Dill TPMS and rely on the audible signal to warn me of a problem. I keep the monitor in the console so I have to look down to check it. I don't look at it too often because it cycles through the tires and takes a minute to get all the readings. My co-pilot reads them out to me on request. When I am on my own I lift the monitor up onto the dash to read it. I am hoping the internal batteries last 8 years the age life of the tires and I will change them then. My experience on the life of factory equipped TPMS vehicles is 8 - 10 years max. and since Dill makes these too I think they may be the same. Also you may be able to clone these as needed and get less expensive replacements vs changing batteries.

I use a EEZRV system. So far no issues and GREAT customer service to date.
I bought the system after having a blowout in our motorhome ('82 Newell Bus). The blowout was in the desert with nothing around. If I would have had this system I would have been in Palm Springs instead of the middle of nowhere.
I take the sensors off of the toad when trailering the AS and move them to my truck. Bought a second monitor & 2 more sensors for the '58 Traveler, very easy to switch.

Since you mentioned that I thought I'd explore.
The system is relatively new (this year) and is available in the 507 system. It works with the 507 monitor.
The batteries are supposed to last five years, so I'm okay with that. The ones in my car lasted at least 9 years when I traded it.
The sensors are $80 each to buy so I feared the system would be too expensive. However, with a B&W monitor and 4 sensors I found it for $277. (Tweedy's)
I haven't seen a package with four sensors and a color monitor yet. ($349 with the external sensors so probably in the $375 range.)

But, I also came across this which concerned me:

SAN ANTONIO — Pressure Systems International Inc. (P.S.I.), a developer of commercial vehicle tire inflation systems, has acquired Truck System Technologies Inc. (TST), a Cumming, Ga.-based provider of tire pressure monitoring and mobile asset management systems technology.

A web site for the TPMS company rather than buying from eBay or Amazon as you need to be able to get to someone that knows something about TPMS and RV rather that a simple warehouse.

For settings on multi-axle trailers I suggest
Low pressure warning at tire sidewall pressure - 10%. You will only get a 10% drop if you have a leak or the temperature drops 50 °F overnight and if it does drop that much you should be toping off the pressure anyway.

Don't bother with changing the High Temp setting as 158°F is a good number.

High pressure warning would be tire sidewall +10 to 20%. Your pressure increase is only 2% for 10F and a properly loaded & inflated tire not running over speed (65 to 75 mph MAX in RV application) should not see more than +50F unless something is wrong.

If you have a Motorhome my suggestions are slightly different as your cold inflation is not the tire sidewall psi but is based on measured loading. I have covered that in my blog on RV Tire Safety.

None of the Nationally known Brands offer a Lifetime Warranty. Some others do but it is not Comprehensive. I would suggest going with a brand that is NOT a knock of Tireminder or TST. Both TST AND Tireminder are sold Nationally through Camping World, NTP, Arrow, Meyer Dist. TST and Tireminder were both also acquired by 2 Large Organizations this year. Tireman I would love to have a discussion, and send you a system for you to evaluate. We have just released our New Widescreen Full Color Display, we include a repeater with every kit, we have Flow Through or Cap Sensors, or Internal Sensors, as well as our Hybrid Sensor for RV or Marine. Can we set up a call to discuss in more detail? Thanks, Mike Benson TST 210-420-0132

Not exactly sure how you defign "Nationally Known". I happen to have purchased Tire Traker unit in 2009 and have found their TPMS both on-line and for sale at large RV Conventions from OR to MA and Wi to GA. I managed to damage (my fault) the original TT400 monitor in '16 and upgraded to their TT500 which has a lifetime warranty. If selling through CW or an auto parts store is what makes a system "better" along with more expensive and less knowlegable sales person I guess you are correct.

While my RV is parked till March I would be interested in evaluating an internal system vs my external system. I did this with a passenger car internal system by Hella back in '09-10.

I will contact you next week.

NOTE I do not sell, service or receive any commision from Traker or any TPMS MFG. I started working with OE internal systems back in '06 when working as a tire engineer for major mfg.

On the TST 507 system, does anyone know the size of the small round (Black ring on the end) power plug that powers the monitor? I talked to TST and they didn't know the size when I inquired about getting a longer power cord with USB connection instead of the old round cigarette lighter plugs. They don't have them for the 507 series units. Since most newer vehicles now have a plethora of USB plug-ins, I'd like to get ahead of the curve.

The monitor is charged from a 12 volt adapter. A USB outlet is only 5 volts so may not work. When charged the monitor will work unplugged and on the rechargeable internal battery for about 8 hours.

on the back of the monitor there may be a symbol next to the power port that defines the voltage and the polarity of the plug. For the size, if there is a Radio Shack store still open in your area, they have a selection of these plugs in their displays to check size with. They may also be able to provide an appropriate adapter...

[Tireman9]

It's important to have BOTH voltage and POLARITY identified when charging TPMS monitor.

I fried mine by using 12v when it only needed 5v

I assume you are looking at the plug on your current charger. Is the center or outside 12v+?
You also need to measure the OD of the plug or compare it to a known diameter plug.

Numerous sizes out there. Find someone with Micrometer or accurate gauge.
HERE is some info and example of variety

[rmkrum]

Yup. Get the voltage wrong, or the polarity wrong, and the smoke that makes the electronics work leaks out.

Once the smoke leaks out, it quits working...therefore, the only logical conclusion is that electronic devices function on smoke...

With the new 2017 F250, there is TPMS monitor system and capability available for the trailer monitoring inside the cockpit.. Does anyone have any data on weather the Ford system is better or should I be looking for some other type system with yet "another" display to read when I start up... I say this, as with the back up camera, the AS model does not work with the Ford back up camera system, so another monitor is needed. I would love them all to work on the Synch system from Ford if possible...other comment, I don't want to break the bank on a TPMS system for the AS. Currently, I have a good pressure guage which I use before leaving. I can see my F250 tire pressure changes when they warm up on highway, by 10 degrees, so I "assume" the GYMs pressure goes up about the same. Any comments and recommendations are appreciated...

[rperrym]

TST tpms users, do you use a booster on your Airstream to get a stronger signal to the tow vehicle. I just talked to TST and they said with the Airstream I would need a booster. I did not need it when I use the TST system on my motorhome, but now have another Airstream and it is recommended per the TST folks.
Wondering if anyone else is using a booster.

Thanks,
Rick

I needed the booster on my 23 Safari. Mounted to the side of the battery box and wired direct.

Must be classified. I Googled and couldn't find any specs, even in the manual. I think you might have to measure the ring with calipers and check polarity with a volt meter.
This is where Radio Shack was great (at least for a while).

You probably buy another power cord, and splice the two for a longer cord.

[Tsunami-v2]

Yup, not much to go on. I'n heading Indianapolis shortly and will stop by Fry's Electronics to see if they might have something available.
