Tire Pressure Monitoring System - Page 2

Screwed on the sensors (snug), sprayed at stem to check for leaks ... if leak, snug up a little more ... respray - check for leaks ... etc. etc. when sensor is on and not leaking then I used the the "wrench thingy" to "lock" the sensor in place. So as to not allow it to come loose and fall off ...

I just did a 5,000 mile trip on my TST 507SG and they worked great!! We picked up a screw in a trailer tire just out of ST. Louis and the alarm allowed me to slow down and get off the HWY with out any damage. I think you've been given some good advise, I recommend you give TST 507 another chance.

You may have tightened the sensors too tight and crushed the very small "O" rings inside. I accidently crushed one of mine this same way. I replaced the O-ring and put it back on without screwing it on so tight and it has worked fine since then.
IMHO, the TST507RV is the best unit on the market, but that is just my personal opinion.
Look down into the sensor stem and I'll bet you find either no O-ring or a crushed one. They are 4mm O-rings and can be bought at any auto parts store, or if you call them, TST will send you several FOR FREE!

So four stops later I'm at the tire shop kinda hoping I picked up a nail or something, but nope, it was the stupid TPMS I paid $385 for!

Anyways, I still want the ease of mind knowing the tire pressure is safe when going 70mph, so I want to replace this one. Any suggestions?

I also have the TST 507 and I believe it to be the best one out there. I wouldn't tow without it as it has saved us several times. In the years I've had it I've not had one issue with it. As I type this we are stopped for the night in a Walmart parking lot in Perry, Florida. Our TST is mounted on the right side of the windshield as it is my wife's job to monitor the tires.

I have the TT-400 unit w/4 sensors...1 yr. warranty and $100 less than the TT-500 unit. Been perfect thus far...about 2000 miles over 9 months.

Another vote for TST. I have the older 510 system. It's always worked great. The only drawback is you have to send sensors to them for battery replacement. However, in 4 years, I've only had to send 2 of them back. I can get readings from the camper when it is on one side of the house and the truck is on the other. At least 100 feet without any booster or external antenna. So far, it has alerted me to a defective brake on my right front camper wheel and a flat on my inner left dual on my truck. The brake issue caused high temps which sounded the alarm. While speaking of rubber valve stems, would I have gotten the alarm for high temp before serious damage had occurred? Thermal dynamics, being as they are, I believe the heat will travel faster and more efficiently through a metal valve stem.
Anyway, I'm very happy with my TST system and their customer service.

Like everybody else also have the TST 507 non flow thru and haven't had any problems so far in fact it worked flawlessly on one trip when the slow leak alarm went off letting us know the tire was losing air and gave us enough time to slow down from 65mph and pull over which I believe saved us from a lot of possible damage. Changed tire which separated at seem and we were on our way. TST 507 paid for itself on that trip. Sorry for your problem.

Santos1060 · 08-04-2016, 01:09 PM

Thanks everyone for the vote of confidence on this particular model. This is going to sound ridiculous, but I seriously overpaid in order to do the dealership a favor because they fixed a huge water leak I had... in one week's time and I didn't even buy from them! So I bought the system from them (overpriced of course) and also paid to have them install it. Figured I wanted it bad enough and they were saving me a lot of money and time by taking care of my water leak instead of having to drive three hours both ways to the dealer I bought from...win/win for both of us.

Anyways, so they installed it and then it failed. I stopped in at Discount Tire on my last trip and they are the ones that identified the leak was from the sensor as they did tests on the wheel and stems to eliminate that.

Either way I go (thanks to your feedback) it seems like I'll be coughing up another $100+ to get the metal stems in place of the flimsy rubber ones.

Really appreciate all your knowledge, this RV has quite the learning curve.

$100 sounds a little high. You can get a set of good quality stems for under $15. Since you probably needed balancing anyway all the tire store has to do extra is a single side bead break and set the new stems. Maybe another 10 minutes labor? There are several sizes of stems so be sure to use the correct ones (some wheels have recessed holes for the stems).

I understand your frustration. I've had my flow thru 507 system for about 2 weeks now. I was also very frustrated but I believe I found the issue with my system losing air. I was so concerned with over tightening that I had not tightened the sensors enough. Once I tightened the sensors all the way not just slightly past the hissing sound all seems to be good. Apparently tightening the sensors can be a little more sensitive then I thought it would be. Good luck!

I put TST 507 flow-throughs on GT and my Jeep Liberty toad. Quite to my surprise, half of the sensor and all of the stem sick out beyond the wheel rims on the Jeep! One week after putting them on, I accidentally bumped one of them and it snapped off the aluminum stem. Thankfully, it snapped off above the valve. So the tire stayed inflated. $100 later, I had a stainless steel stem and was back in business. This may be something peculiar to a Jeep Liberty, but check on your own toad if you have one and see if it sticks beyond the tire and wheel profile.

Couple of things that I found on my e450. I installed the passthrough tire pressure system and did loose inside pressure.
I have the plastic valve stem extensions .
The reson for the loss of pressure was two fold.
1 tightness of the Allen screw in the stem
2 probably moving the extended stem

Solution is very simple. Thread Tape.
What I did was remove the outer rims thread tape the extender bottom and top. Attach the tire pressure valve tighten and secure the Allen key. Yes put the outer rim on and correctly tighten all well nuts.
I have had no pressure loss over the last 2000 miles

I have the eezrv system, almost went with the TST but liked the display on the one I bought more. Both have high and low pressure alarms and so far I've been very pleased. As a prerequisite I did install chrome valve stems on all six tires, as it was suggested her in the forum.

Santos1060 · 08-17-2016, 03:22 PM

Again, thank you to all for the information. I'm at the stage now where the dealer is telling me they don't have a tire machine so they can't bolt in new metal stems. So I called up Discount Tire and they don't stock what the Sprinter 3500 w/Dual rear tires needs.

Can anyone point me in the right direction? Perhaps with a link or brand/model #? I'm looking at Amazon now and there's so many options I just don't want to order the wrong thing and have another set back. Trying to get this done before Labor Day!

My goal is to make the TST 507 TPMS work with metal stems/braided extensions for the inners. Heavy sensors are flopping around on the rubber extensions and causing leaks.

Thanks in advance!

That's where I got mine. Called prior to ordering to verify that I was buying the correct stems. Very helpful people.
