What are normal tire temperatures??

[Fred from Ga]

What do these systems cost?? Haven't thought about them but this interest me. Thanks.

And at the risk of hijacking this thread - and hopefully without turning it into a long, long, long argumentative one - can those who have purchased a TPMS (or who have shopped for one) share the main features that they considered when making their purchase decision for their chosen brand - and what that brand was. Thanks!

The system I bought on Amazon is a 10 tire tire pressure monitoring system for a 6-tire motorhome towing a car and has flow-through sensors for the RV and cap sensors for the tow car. I paid $489. I see that a RV only 6 sensor system is on sale for $279.
1. My system has a dash-mounting monitor that shows tire pressure and temperature at all times.
2. It alerts users to abnormal tire position as well as low and high tire pressure levels with alarm icons, red light, and an audible warning.
3. The high pressure, high temperature, and per axle low pressure warning levels are user-adjustable.
4. The light-weighted external cap sensor (.45oz) installing on the tire valve stem is waterproof and its battery is user-replaceable.
5. The monitor has a rechargeable battery and is portable.
6. The sensor signals have long range so therefore mostly it is not necessary for motorhomes and big rig tractors to install a signal booster.
7. HCI developed the TPMS systems in USA by in-house engineers and make all products in its own factories.
8. Has immediate audible and visual alarm for rapid loss of pressure.

There are several systems available from different manufactures, but the Tire-Safeguard system seemed to have all the features I felt I needed. I am very satisfied.

I bought a Tire Safe-Guard unit several years ago, for the same reasons Rambling Man mentioned. The heat sensing capability was very handy when I was having brake caliper problems, my unit has 4-wheel disc brakes. It has also saved me from flats when one of the valve extenders failed and I when I had a damaged tire. I have had to replace the batteries on all the senders as I've had the unit 6 years.

I had planned to stay away from brand specific recommendations but since Wiley has posted this I will note that the Tire Safeguard is the system we plan to be the next TPMS in our coach. A few of the folks on the Monacoers yahoo site have switched to the Tire Safeguard and are very pleased. One user is also a member here, Richard S., and he previously owned the Doran system that we have. He became fed up with the battery issue and moved to the Tire Safeguard. He is very pleased with the performance. He has the pass through sensors on his coach and the non-pass-through sensors on the toad.

We purchased the EezTire system while in Quartzite this winter .There were multiple venders there and after lots of reading and research we chose this one. They even gave us the repeater for free a couple days layer when we were having issues picking up the toad. We are new to these systems and I live the info on the tire temp. It certainly makes sense

[Retd_ontheRd]

Thanks everyone for your information, opinions and advice. This will help all of us who haven't yet bought a TPMS.

After asking the question in my previous post I came across this advice on selecting the best TPMS by Roger Marble, the retired tire engineer who often posts on the RV Travel Newsletter and also has his own tire safety blog here.

More info to help in the research...

Same result I get. I use a digital thermometer with laser pointer. I also check the wheel bearings.

Some TPMS systems do monitor temperature as well as pressure. I know the TST systems does. I believe the pressure pro does as well as others.

122'F won't hurt a thing many time black top in the sun is 130-140'F You run down the highway on that for a hour and your tire will be the same temp.

And not to hijack the thread, but IR thermometers are also handy for other maintenance tasks around the RV, for example checking the efficiency of your air conditioners or heat pumps. They make it easy to measure the difference between input and output temperatures, to check against specs. They're also great for finding air leaks around slides, double-checking engine & transmission temperatures, and checking fridge & AV cabinet ventilation.

My two cents.

X2 I do exactly the same thing.

[TST System]

Hello Sir,

That is great you got a TPMS.

Typically tires will begin to fail between 185 and 205 degrees. The TST is set to alarm when the tires reaches 157, which is well below the catastrophic failure point, but well above normal operating condition. Your tires when driving should be approx. 15% to 22% above ambient temp. The system will alarm on such situations as a Hanging Brake Caliper, Hot Bearings or Rotors, or even a Tire Manufacturer Defect like a bubble in the side wall. Anything that causes that tire heat up unusually will trigger an alarm once the temp rises over 157.

I hope this answers your questions. Feel free to contact me directly if you have more questions.

Thanks,
Mike Benson

And I am paying a lot more attention to my tires and what they are doing after an unexpected flat on the other inner dual tire about 4 months ago. What I don't understand, and have not seen information is what are typical operating tire temperatures for a properly inflated tire? My tires are essentially 295/70R22.5 standard RV-truck tires. If I am running them within their load limits, at proper pressures, and lets say after 4 or 5 hours of normal highway driving, what typical temperatures should I be seeing on those tires?

At what temperatures would I start to worry that something was wrong with my tires or moving toward a blowout?

Thanks in advance
