I know this is not easy to grasp and a bit counter-intuitive but there is data on this in the industry. Personally I do not pay a lot of attention to the temperature reading as it goes up and down throughout the day depending on the Sun or if it's raining or how fast I am driving. Since I run my tires with enough inflation to give me about 15% extra load capacity over the measured actual load on the tires I seldom see more that 20 to 30F rise and more normally they run in the +10 to + 20F range. IMO pressure is the most important thing for a TPMS to monitor and report and I have confirmed my sensors read +/- 2 psi from actual based on a ISO calibrated digital gauge.Tireman9https://www.blogger.com/profile/09813984937064446653noreply@blogger.comtag:blogger.com,1999:blog-4197373783392349499.post-35995259229344811772016-07-26T07:28:45.357-07:002016-07-26T07:28:45.357-07:00RE "tire blow".

I suggest you review my post of April 12, 2016 to learn more. TPMS warn of air loss. Have you tested the response time of your sensors as mentioned by Ed Price?Tireman9https://www.blogger.com/profile/09813984937064446653noreply@blogger.comtag:blogger.com,1999:blog-4197373783392349499.post-48208912653537598642016-07-10T13:01:55.964-07:002016-07-10T13:01:55.964-07:00I purchased Tire Minder a few years at an RV show...I purchased Tire Minder a few years at an RV show. I have 2 friends who flipped over totaling their vehicles and trailers due to a blowout. I don't want that happening to me so I have become a tire freak. I always check my tires before a trip and on my return. I always use the tire monitor. One time it did blink red due to an air loss. I checked the pressure and indeed it went down suddenly 8 pounds. I inflated the tire with a battery powered inflator and stopped a few times on my way home. Next day I had the tire checked and the stem was bad.<br />I will never take the trailer out without using a device that monitors tire pressure. I like the Tire Minder, but it is not very easy to calibrate. They have a new one out and I hope that one is more user friendly.Sharon Bhttps://www.blogger.com/profile/04717443531639421006noreply@blogger.comtag:blogger.com,1999:blog-4197373783392349499.post-18530373949933998392016-07-10T02:45:33.468-07:002016-07-10T02:45:33.468-07:00I have tested my sensors by unscrewing one from th...I have tested my sensors by unscrewing one from the valve stem, and the warning is nearly instantaneous. Perhaps you should test your own sensors. I suspect that the sensors, receiver and code are likely created by some single Chinese company and marketed with slight variations in the case and display, leading me to suspect that they all work pretty much the same. Still, for your own confidence, you should test how your system actually works.Anonymoushttps://www.blogger.com/profile/03757095726347147302noreply@blogger.comtag:blogger.com,1999:blog-4197373783392349499.post-52850320145365390962016-07-09T22:55:23.417-07:002016-07-09T22:55:23.417-07:00We are full-timers, with a 43' sierra 5th whee...We are full-timers, with a 43' sierra 5th wheel travelling allover North America. I've been using the Tire Tacker TPMS for 2 years and in my opinion they are worthwhile. them installed the 4 RV wheels, as as on all 6 wheels on my F350 tow vehicle. Prior to leaving an RV park in the morning, I remove all 4 TPMS' on the RV to reboot them. Takes 30 seconds. Doing this I know the monitor cab has fresh data and good to go. The PMS's on the truck are constantly up to date as this is our transportation once we drop anchor. Of course I check the tire pressures the night before a travel day to verify pressures.<br /><br />I've had a low pressure warning on one of the dualies on the truck - lst stage of tread separation - bad tire. I've also had a low pressure warning due to a bad valve stem. I now run stainless steel valve stems all around. <br /><br />Also, I got tired of using cheap 12v tire inflators. I went a bought a compact 120v 6 gal air compressor. Very quick to inflate the tires on my truck and RV as needed. The compressor tank shpould be sufficient if I have a low reading on the road. If necessary, I can fire up my portable 2000wn generator. Of course, now that I've got a decent portable compressor, my tire pressures rarely need topping up.

I then compare that pressure to what my TPMS monitor says and I write it down. Now I know what my monitor should read for each tire. In other words if my digital gauge says 100 lbs for each of 4 tires on an axle I know they are all equal. But maybe my TPMS monitor does not read exactly 100 lbs for each of those tires. Now I know what my monitor should read for each tire.<br /><br />At least once a month I take each sensor off each tire to make sure it goes to zero. I then reinstall the sensor to make sure it returns to the correct pressure. If the pressure is off I then check again with my digital gauge and adjust as needed. <br /><br />Since the technology is now available we cannot imagine going anywhere without a TPMS.

I would think that the stem and sensor, which are whirling around in ambient air, would be cooled by this effect and read substantially lower temperature than the hot air within the tire.Anonymoushttps://www.blogger.com/profile/03757095726347147302noreply@blogger.comtag:blogger.com,1999:blog-4197373783392349499.post-9640148323890364302016-07-09T06:51:27.087-07:002016-07-09T06:51:27.087-07:00The best tip is to NEVER use these on rubber valve...The best tip is to NEVER use these on rubber valve stems. We learned the hard way. The sensors weigh 13 grams and the centrifugal force will deform the base, eventually causing catastrophic failure. If you contact them or read their brochures, purveyors of these devices will recommend metal stems but won't require them. Otherwise, TPMS are great.Anonymousnoreply@blogger.com
