Traditional TPMS

[jason_sos]

I have found lots of aftermarket TPMS systems that just fit onto the end of the valve stems, but I have some concern over these:

• Balance
• Theft
• Falling Off While Driving
• Physical/Water Damage
• Air leaking (since they must depress the valve stem to measure pressure)

I would much rather have a traditional TPMS system where the sensors are inside the tire. I am already looking to replace my tires, so it's not a big deal to install them while they are doing the tire replacement. The question is, has anyone found any of these traditional TPMS systems that communicate with a receiver that would sit on my dash?

Google can be your friend if you let it: https://www.google.com/#newwindow=1&...ternal+sensors

I've had a TPMS system with external sensors and have used it for years with no problems, air loss or theft as they have anti-theft provisions

Your concerns are unfounded.

The flip side is that when internal sensors fail, you have to dismount the tires to replace them.

That said, here's a company with what you seek:

So the external sensors will never fail due to physical damage or water, be stolen, or cause an imbalance in the tires? I find it hard to believe that they won't cause an imbalance considering the tires are balanced with weights weighing fractions of an ounce being used. I've had regular valve stem covers come off tires before. I can only imagine one weighing several ounces and costing $50 coming off at highway speeds.

I have never, over the entire life of my truck, had an internal sensor fail.

TST has an internal system that mounts on a band like OEM systems. They have a 7 year battery life. That is approximate life of your tires. TST will send you units to exchange with the old ones for just the cost of the batteries

Jason_sos So the external sensors will never fail due to physical damage or water, be stolen, or cause an imbalance in the tires? I believe you know the answer to your question, EVERYTHING is subject to failure, theft, damage including internal TPMS sensors.

The couple of ounces that the sensors weigh won't make a difference in balancing weight of a motorhome tire. You'll NEVER feel it and the tire won't wear out due to the sensor.

We gave you a couple of choices both internal and external so USE THEM.

I've been using the EEZTire 515 TPMS for several months now and am very happy with it. It is external with theft protection. The pressures read almost identical to my two different tire gauges, so it seems to be pretty accurate although the system is primarily monitoring for rapid air loss, etc., that could lead to a blow out.

Thank you for the suggestions. I am going to check into them.

Another reason I don't like the external ones is that I simply don't like the look. I don't like having a big ball shaped thing on the wheel, I just think it's ugly. My tires also have rubber valve stems, and the ones I have researched require metal valve stems, so I have to have the tires unmounted and have new valve stems installed anyway.

It would be very difficult to steal, or even realize that there is an internal TPMS on the tires. This isn't the case for the external ones, it's very obvious that they are there. The external ones also have a much higher chance of physical damage, because they are sticking out from the tires. I take my trailer to remote areas where I am literally driving in ruts that are barely wide enough for the tires, so anything sticking out from them is going to get banged around.

Again, thank you for the replies.

I used to be a Pressure Pro distributor/dealer and used their system. Then I bought a TST 507 system for the DSDP. The present Magna came with the internal SmarTire system. When I had my tires replaced late last year I had new internal sensors installed. I like the internal ones since they don't require removal, and no worry about theft.

In my one year of experience with external sensors, none of these are worth worrying about. If you want, you can put a locknut on the stem to help prevent falling off or theft - mine came with the locknut. They do have a rubber washer or o-ring inside to seal the air. Who's going to steal one? They would need to have the same system. I don't think I've ever heard anyone mention external TPMS sensors being stolen.

Meanwhile, I do remove mine between trips - that way they're not sitting out there as an invitation to various problems.

CoachmanJay, these are TST. When we were shopping for internal sensors about a year ago, sales at Truck Systems Technology recommended these because they leave the OEM stems alone. Discount Tire store installed and balanced for $15 a tire. At 6 or 7 years, when it is time for new tires they do not charge to exchange out the replacements we will purchase from TST. We have these on 6 truck tires and the tow dolly. We use screw on cap style sensors on whichever of the three toads we happen to use on that trip. Works great, lasts long time. No annual battery change or stem problems, but to each his own.

In regard to the exchange. If you go to a tire dealer to have the tires replaced, they have to remove the sensors then do you send them back while your coach is sitting with no tires or does TST send you the sensors before you get new tires and you then return the old sensors? Just wondering ????

[coachmanjay]

TST will send the replacement units so you have them prior to changing your tires and then you return the old ones.
