I wondered about this. I have the steel wheels and there is a plastic cover over the hubs. Do I need to remove the plastic cover to check the hub temps, or would I feel it was running hot it I checked it with the plastic cover in place?

Bill when you touch the hubs even with the plastic caps on , you will feel if it is hot . Also feel your tires and you don't want them to be real hot . Pat

Not very accurately.

How about the wheels - the temperature of the wheel around the centre cap will be much closer to the hub and bearing temperature than the surface of any cap, especially a plastic one.

Separately, I agree that you don't want the tires to be hot... which is likely to be due to underinflation or overloading, rather than bearing issues.

I know sometimes what I want to say comes out differently . If the whole wheel is hot , touching in different places not good . He was focusing on the plastic cap so that is why I went there . Pat

Tire pressure monitoring update

I just called TST and talked with Beverly. [This company appears to make good products, as apparently do many of their competitors.]

With their 507 internal system, when due for battery replacement around 7 years, you order replacements at about $30/sensor vs $80/sensor new, have your tire shop swap them (maybe at the same time you need new tires?) then ship back the old. That should work smoothly, much better than if you had to return yours, then some weeks later receive the rebuilt units and have them installed in a second visit to a tire shop.

According to Beverly, the internal sensors are no longer mounted to valve stems as shown on their website, but are attached to the wheel by a band encircling it. She said most car manufacturers use the same type mounting.

They recommend metal valve stems for their Flow Thru 507 sensors (you don't need to remove the sensor to add air to a tire), but the standard 507 sensors are lighter and are ok with rubber valve stems. So I ordered the standard 4-sensor set at $259. When I replace tires, I'll ask for metal valve stems – if I can remember that long.

The standard 507 Sensors use a special wrench for theft resistance. The Flow Thru twist on, then use an Allen set screw for security – which would allow a determined thief to destroy the valve stem threads in removing the sensor. TST receives few notices of sensor theft, and that also doesn't seem to be much of a problem according to this forum.

The external 507 sensors have user replaceable CR1632 batteries, claimed to last 10-12 months, and longer if you remove them from the tire when in storage. I plan to do this for battery life and added theft resistance. [First use a silver craft pen to write the tire position on each sensor so I don't have to reprogram the monitor. Beverly said these remain legible for a long time.]

Thanks for that tip to mark each sensor to it's tire. Haven't gotten around to installing mine yet, but have been thinking of not bothering with the locking cap which can be removed. Good to know they have few reported instances of theft.

Good information . Looks like I will get the standard sensors . One question would the wireless frig moniters cause any problems do you know ? Pat

I don't know, but we have the fridge monitors so we will find out.

TST is the system many people were using over on the Casita forum several years ago. Many people seemed happy with it so I tried it. I had problems with losing the signal and having false alarms. It may have been because of the distance between the sensors and my receiver because if the length of my truck. I ended up returning it and purchasing the Dill that has a external antenna. Also the sensor on the end of the valve stem stuck out pass the wheel a little and just looked like it could be hit. Its more work to install the Dill but from my experience I found it more reliable.

They may have made improvements in the sensors since I tried it about 6 years ago.
