It is difficult to give any personal experience advice over the long term but at least you can weed through opinions. The issue is that most people have not owned several types so a comparison is difficult. Each purchaser usually has a reason for the one they bought. My reason was reviews and price along with few posted issues. I saw it demonstrated at a Rally last Feb but was not ready for a TPMS yet- still shelling out for other stuff. The British couple doing the demo was great help. TechnoRV/TechnoGeek. TechnoRV - The RV Technology Specialists ... with the best service!

They have videos on their stuff. They also explain usually WHY they solicit the products they have - they have picked them as items they believe to be the best choices. The Traker monitor is small and flat.

Just went on their site. See the videos and note the size of the monitor in his hand. Its $219 for the 4 sensor system BTW.

Another idea is that you can go on youtube and look up various systems to get an idea about setup, etc. I did that for one system and realized I would probably not use it with the amount of work. Also, if shopping online, be careful as not all "bulb looking" sensors are the same. Some are bigger and heavier (note the weight spec). Regardless of what is said and brand purchased, I would also have my tires balanced with the sensors on. I experimented at the tire place with on and off and it was a .50 difference on their machine even though the sensor is .30 in weight. While on the subject, I originally had the tires balanced at Sams where I bought them but they had trouble with their arbor not matching the trailer wheel. I went to a truck place with a load balancer and it was amazing how far off they were from the previous balance!

That Tire Tracker System looks to be identical to the one that i bought under the Hawkshead name! I'm guessing that it is!

I use centramatic wheel balancers on our trailer and hope that they would compensate for any minor imbalance caused by the sensors.

Use Hawkshead - Winggeezer has already discussed it in detail.

I like it and mine syncs up very quickly and I do not use a repeater/amplifier. The pressure readings are spot on.

One caveat for all are their temperature measurements - they are close but none will win a prize for accuracy. They likely will be in the range of plus or minus three or four degrees F. That said, I do value having it since it does give you information about the general temperature condition of the tire.

Contrary to what some would recommend, even with the absolute best, most expensive, super duper tires, I would still use a TPMS. There are road hazards that will take one of these tires out just like any other. They simply aren't bullet proof. I have many friends who have upgraded their tires to the super duper brand and they all use TPMS.

Wait, I didn't recommend not using a TPMS, just stated I don't use them on our 16" Michelins. I do believe if there is a perceived problem with tire blowouts, replacement of the tire type is the first course of action.

Okay Doug - regrets for not understanding your response properly.

Thanks again to everyone who posted in response to my query today! We decided to order the Truck System Technologies solution. We liked the ease of programming, the small console that we can carry about the rig while visually inspecting tires before taking off in the morning, the warning LED and sound, the flexibility of choices for sensors and the ability to replace batteries in the external sensors. We're putting sensors on every tire, including the spares, for a total of ten. (After all, a common frustration is discovering that your spare is flat when you most needed it to be...not flat.) We've ordered the repeater in case we need it, with the assurance that we can return it easily if it's not needed. We'll also look into whether we need to re-balance the tires after attaching the sensors.

Great. From what I found some of these systems have changed from when they were first introduced so you really have to shop and make sure that the one you pick does what you want- basically warn you against a bad situation. The nice benefit I find of a TPMS besides warning is the checking of the PSI before travel. Just looking at a monitor is much quicker than running around with a gauge to each tire. On iRV2 forums I read a really heated thread on TPMS when I was looking. They were disputing the benefit of valve stem based systems versus in-tire sensors. There is ALWAYS a lot to learn about whether RV TPMS or commodes!

I use a "racing class professional digitial tire pressure gage" to set and check tire pressures daily. My TV has an onboard air compressor for the air suspension and has an air chuck beside the license plate to connect an air hose, if needed. I elected to go with the Dill TMPS 1506-453 system from Discount Tire.

That kit has six sensors, so I have a spare. The spare tire sensor can be energized in the display if an on road tire swap is necessary and also disable the sensor in the tire with an issue. Since the sensor batteries are only energized when the tire rotates, the spare tire would throw an alarm as hopefully it is not rotating in the horizontal plane under the trailer.

This system comes with the model 1900 display which has been updated for better visibility in direct sun light.

Having the sensor inside the tire will give more accurate temperature information than a rosebud out on the end of a valve stem sitting in the cooling air running down the road.

I also use Centramatic wheel balancers on both the trailer and my Honda motorcycles. The motorcycle tires and wheels are light enough that no wheel weights are necessary. Once moving, the tires are immediately in balance. With no taped on wheel weights to fall off (as in the past), the ride is far safer.

Good luck with your decision making process.

ahh, as with the iRV2 forum thread, Switz brought out the inner/outer sensor question. Here is what they summized in the thread regarding that issue.

"Either system type is tested to read temps/pressure with a margin of error."

The minder/traker system is 5.0 degrees (temp)/4PSI margin of error and the Dill system is 5.4 degrees (temp)/ 2PSI margin of error. The TST system is 5.0 degrees (temp)/2PSI MOE. The systems do what they are supposed to do. As to the setup and operation- that is different. The TST system is great. It has certain caveats like all of them. I pulled my tablet out this is what difference I could find compared to what I purchased - the monitor is bigger, same types of readings, 13gm sensors vs 9gm (Traker)- 22gm for the flow thru TST, sensors stay on all the time and have to be pulled to shut off (zero psi) vs. Minder auto off, TST 5 min transmissions versus 4 minute ones. The complaint I found about auto off sensors is that you must move the rig first to get a reading. That is no issue for me as I get the unit from storage and take it home to load before departing.

I have an extremely accurate tire pressure gauge and three vehicles with TPMS systems. Quite frankly, I think that TPMS gives drivers a false security based on the fact that these systems are not all that accurate. Interestingly enough, our most expensive German sports car is the least accurate!

No problem checking the tire pressures every morning as I can also do a visual tire check at the same time.

Sure, as it should be Denis4x4. The rationale for having a TPMS for Airstreamers is being able to know what is going on "back there" while traveling before the steel belts eat the side out of the trailer- at least shorten the event. Motorhomes are needy too as they may get stranded.

Speaking for the only system I have used, the Dill. When I check my tire with my stick gage and then set out as soon as the sensors report for duty they are darn near spot on to gage.

I'll just pose the question and let others answer.

You are monitoring temp. I can think of 3 sources for heat that we should be concerned about. Ambient temp from outdoors affects us all.

1. Tire created heat from under-inflation.
2. Failing bearing heating up and creating heat.
3. Brake drag creating heat.

No, I don't have any data about the brake or bearing failures and tire temp.

You can choose an external or internal monitor. Which one do you choose?

Its good to have a discussion about a safety topic and I think the biggest issue it to be pro-active, do SOMETHING, choose but act for your own safety and others. One thing that did enter into my decision, it was coupled with new tires so installation was not a factor.

Hardly a week goes by that I don't see a utility trailer or camper on the side of the road with a tire issue.
