I had a valve stem on a previous toad that gave me a similar sealing problem. I could feel with my finger that the end of the stem was a little deformed, and a few minutes work with a small file and some fine emery cloth fixed it.

Or it could be the little rubber seal inside the TPMS that is leaking. Sometimes if they are screwed on too tight the seal will deform causing a leak.

Reading this there may be some confusion with how the pressure pro system works. The pressure pro sensors "update" approximately every 5 minutes. However if pressure in a tire with a sensor installed drops below 12.5% of the baseline pressure an alert is immediately sent. Baseline pressure is the pressure within the tire when the tire sensor was installed.

Having some experience with the pressure pro system has taught me one lesson. I installed all the sensors on my towed and coach several months ago at my home in FL with outside air temps in the upper 80's. I made sure the tire pressures were exactly where I wanted them to be so the unit would record the correct baseline pressure for each tire. Our first night in Michigan in late July at 3am in the morning the pressure pro alarm sounded. Further investigation revealed one of the towed tires had dropped just below the 12.5% threshold initiating the alarm in the early morning 55 deg outside air temp.

I did essentially the same for one valve stem that always had leak problems with the TPMS. A few minutes with a fine file was all it took to make the contact surface smooth and "square" so that the seal in the TPMS sensor made good contact.

I had a leaky sensor this spring at Yosemite rally.  I just discarded the sensor and ordered a new one.  As always, should have checked here first!

That's one reason I prefer the TST's user setable trigger points over arbitrary presets. The temperature related pressure changes can be quite different for different size tires. At 12.5%, 35 PSI toad tire need only drop a bit over 4 lbs to trip the alarm, while a 90 PSI coach tire would need to drop a little over 11 lbs.

I will check to see how the stem feels. I know it is the valve or stem because when  I switch the sensors around I only have a problem with that one tire. When I contacted the manufacture they told me the sensor hardly ever leaks and to try tighten the valve.  When I still had problems, they sent me a new one.  I will now purchase another set for my toad.  Great customer service.

Estuary:  if it is an inner dual, it might just be a valve extension problem.

So which is the best system, in your opinion and why? I have two left hand and am not mechanically inclined at all. Need something simple, yet effective.
thanks

My only experience has been with two different TST models, first the permanent battery model 510, and later on the user replaceable battery model 507. I have had zero problems with either model, and any questions I've had were quickly and accurately answered by TST tech support. I prefer the removable cap style sensors to the flow-thru style, and installation and setup is just a matter of following the clear directions that come with the system. If you can screw on a valve cap, you can install a TST TPMS. If I should need another system in the future, TST will no doubt be the first place I look.

I have the Eezrv system and am very happy with it. I chose it for what I felt was a better display than others.

I have one tire that will not be friends with the TPMS.  Goes flat when I put it on.  I know it is the valves fault because if I switch the TPMS around the same tire goes flat.  If I ever have a problem with that inner dual, I will change out that valve stem   Anyone else had a similar problem?

Had a valve stem slow year a few years ago. Wasn't sure what the problem was but the tire place put it in a big tub of water and discovered the bad stem. They said it is fairly common.

Curious why you don't get it fixed now instead of waiting till you are 40 miles from nowhere which is where all these problems come to a head.

Our EzeTire Monitoring system has saved our bacon about 5 times in the last 2 years and over 30,000 miles and I would never leave home without it.  I word of caution (learned the hard way) Never install them on rubber stems.  Be sure you change all your valve stems to short metal ones.  I have to change the batteries once per year or they fail after about 13 months.  Batteries are easy to change and not expensive.
All I can say is "Get a TPMS and use it every mile you drive! "

Hi Arch
The only time I have problems with the tire is when I attach the sensor.

So I will just check the ire pressure with a manual gauge.
