    Initial issues followed by good service from tire minder

    October 07, 2016
    I purchased this system in early July 2016 from the Houghton Lake MI store and headed on out west to Vancouver Island, then back through the northern states ending up in Pennsylvania and finally back home to southern Ontario by late September. We have a 38 foot 5th wheel. Initially the system would give me occasional no signal messages even after I mounted the booster unit on the underside of the trailer at the front. Also on the receiver the backlight would flicker now and then. I talked to Tire Minder and without hesitation they said would send me one of their new Rhino booster units and a new receiver. I had them ship these to family on Vancouver Island. Once we got there and I got the new booster installed, I had no further issues. The new receiver's backlight also worked fine. I am happy with the system. Besides giving a safety factor, it is a convenient way to keep tabs on tire pressures & temperatures often. The system comes with a good comprehensive manual, and the customer service was very good and fast. One thing though; when you disconnect and turn the receiver off while parked, make sure you turn it on when you hit the road again. The receiver won't tell you anything if it's turned off!
    Pros: Easy to install, Works well once installed, Quality , Excellent detailed printed manual

    Unit is now installed. My old system constantly scanned each tire showing psi and temperature. My TM 77 does not continuously monitor tire.
