TPMS

That was not the case for us. We have had the 510 TST system with sensors on the valve stems for 5 years. We were pulling into a lot when our temperature alarm went off and was showing 165. As we got out of the truck, we could see the tires were fine but could feel a tremendous amount of heat coming from our middle driver side wheel on our 5th wheel. It turned out to be a stuck brake caliper and the heat emanating set off the alarm. Did we lose the caliper? yes. But the alarm going off saved our rotor, tire and possible fiberglass damaged because the TST system let us know in time. Hugs, Di

Temperature measurement is only accurate on inside mounted monitors. Temperature is important to monitor when brakes are too hot or bearing are running to hot and are near failure. I monitor the temp closely and a few degree above my normal range means something is going wrong and it is time to pull over an find out what. I burned a bearing, and saved my axle because of temperature monitoring. I doubt that an outside stem mounted sender would have allowed me save and axle when the bearing gave out.

I have the TST system with removable batteries and am not totally pleased with it. First it wouldn't always pick up the sensors on my 38' 5ver so I had to put on the repeater, seamed to work OK for awhile after I did that. Then last year it couldn't really be trusted at all. Some of the tires would not change pressure or temp for 1/2 hour or so at a time, tire could have fallen off for all I know. I never really cared for their display either, Oh and I changed the batteries every spring.

So what other brands are out their that are good?

I have never changed my batteries, have never taken them off my fiver, and have probably traveled over 25,000 miles towing with them. Never a problem and I don't have a repeater.

I would argue the point made that these sensors do not monitor the air inside the tires. I can hook up my fiver in the morning and my sensors may display 100psi and 60 degrees. After a few miles on the interstate they will be up to 104 or 105psi and 70 or 80 degrees. The faster I run the hotter the inside temp goes.

They are all limited to the same amount of transmitted power which limits range. Where do you have the display mounted? That can make a lot of difference. Mine is top center of the dash and I've never had a problem.

Have you contacted TST? They are very good to work with.

BTW the display will tell you when a battery is low, mine usually last 2 years. When the first one is low I change all 4 and carry spares in the RV.

You probably don't keep your trailer in public storage :)

True...I am able to keep it at home. Never thought about thieves! :E

There is no difference removing a sensor to removing a valve cap

My flow thru have a "lock" on the sensor where it screws onto the valve.
A small allen wrench(provided) is needed to take off the sensor which makes taking it off a pita.

The TST 507 also requires an included tool. But it just slips around the base of the sensor and the sensor and tool unscrew off the stem just as a valve cap would, and nearly as fast.

Thank you for all of the replys.I think I'll get the non flow thru sensors.
