TST Tire Pressure Monitor System - Interim Update

I just installed 6 TST 507RV Tire Sensors on the Toad and 2 front tires of the MH. I will install sensors on the rear tires next week when the weather clears.

After a little learning curve on setting the sensors to be read by the monitor, I tested the sensors on the Toad by using the monitor while driving a couple hundred miles around the area going different locations on the Interstate and city roads.

Once set, it works great. Now while towing I don't have to be too concerned about the tires, if i pick up a nail etc.

I received the initial shipment from tst in 3 days at a temporary address. I will receive the additional 4 sensors today 3 days after placing the second order.

The car has short rubber valve stems. They are situated with enough clearance that they do not rub against the wheel covers while running down the interstate. However, when I get a chance, I will probably change out the rubber stems for metal.

The MH has steel tire stems. It was a little challenge getting them on the front wheels due to the location of the tire cover. I needed about 1/4" to be able to install them without hitting the wheel covers. I talked to a tech at a local trucking company, and he told me I could carefully bend the stem. He indicated that is what they do all the time on the big trucks when installing them. I used a rachet and socket as he suggested, and very carefully bent the stem the 1/4" needed for clearance.

The monitor picked up all 6 tires within seconds and as I monitored them during the day, the heat from the sun caused a change which was recorded on the monitor.

I am convinced and confident that the system works as advertised.

One more toy, but an important one. I did a lot of research on tpms systems over the last year. I think they all may be comparable, but I went with the tst for the ability to change the batteries myself, and their reputation for customer service.

The sensors are lightweight and easy to install with the special wrench sent with the package. They sent 2 wrenches, I keep one in the car and one in the MH.

Good Luck with your choice.

I bought a set last year with the flow-through sensors. Worked great, except the length of the longer sensor combined with the angle of the valve stem (metal) allowed them to project beyond the sidewall of the tire! I actually busted up one when I scrubbed a curb at a dump station, so I contacted TST who exchanged them for the "old style" button sensors - even the damaged one - at no charge. Now they tuck in nicely & are well-protected! Just sayin...

I have the Doran360 tpms and have been happy with it. Have never locked them in place or had one come off my metal stems. Doran does say NOT to tighten them too tight as that can damage the inner seal. I was also impressed with the TST demo in Quartzite. I do take the sensors off when not traveling to save the built-in batteries. My first set of sensors lasted just over 4 years.

TST owner here for about a year and a half and satisfied with the product. I've got the older style with the replaceable batteries. Did not use locktite.

I also check all vehicle tire temps whenever we stop with a point and shoot thermometer. Just look for one that is significantly different from the rest. Gives you something to do while the gas pump is taking all of your money. Cheap and easy to do. I have also used the same pressure monitors. They work well. No need for loctite.

Have had the TST system for several years now and love them.

Though I don't remembering that they caution about over tightening their sensors on the stems I just wonder how many users immediately snug them down REAL tight and then have problems with them leaking in the near future. You've got a real tiny o-ring in there that likely could be crushed fairly easy. Maybe on a new installation go easy on the tightening and then observe for any leaks. Or use soapy water. Just a thought.

I bought the tst system about a year ago. Recently I upgraded my sensors to the new "pass thru" sensors. They offered to give me a discount for trading in my original sensors.

I had an issue making the new ones work (my fault) so on a recent trip to FL I took a small detour near Atlanta and Mike at TST calibrated everything for me and showed me what I did wrong.

Worked great with the older sensors, works great with the new sensors. You won't be disappointed.

Thanks for the input and your thoughts.

Looking forward to getting them installed.

I'll post the results and how they work after install and running with them for awhile.

Now that you have a few days till it arrives, you can put on metal valve stems if you haven't already. JMO

Thanks, the RV came with metal valves, that won't be an issue.

The valves are a little close to the wheel covers, which may take some adjustment.

I would not use Loctite on them if you ever want to get them off. To remove something with red Loctite, it often requires heat. With the blue loctite it requires a lot of torque. When I mounted my towing baseplates to my Jeep Wrangler, on the driver's side, you use the bolts that hold on the steering gear box. The factory used blue loctite on them. My impact wrench, a very high torqe IR model wouldn't do it. I had to use a 1/2" x 18" breaker bar with a cheater pipe to get them out. I realize there's a differance between your valve stems and my steering bolts, but I think if you use Loctite on them, you'll ruin either them or the air monitors when you have to remove one. If you have problems getting them to seal, I'd use just a touch of noon-hardening pipe dope on them.

I've used Loctite Blue 242 for years on bolts and nuts that require eventual disassembling, including TPMS sensors and valve extensions, without any issues. That's what the Blue 242 formula is for, and it has always worked fine for me. Don't confuse "Loctite Blue" with "Loctite Red" that is sometimes packaged in a nearly identical tube though.
