In my limited experience, stay away from Tire Minder model RV-4. Arrived with a dead sensor that took arm wrestling to get a new one.
Then after 1:40 of travel time the sensors started dropping out with “no signal”. Let it sit overnight and then works for another 1:40 (must be a contract thing lol). Again more arm wrestling to get a whole new system. Both of these events required sending the bad parts back - postage paid though.
The new system had the same 1:40 no signal problem. By then I was disappointed, frustrated, and fed up. I bought a TST system which has been flawless for 2 years now!
I’m using the Tire Minder in my 2006 tow vehicle (only has a warning light) which is fine for short trips. But now one sensor is dead, no new battery or re-pairing revived it so I contacted Tire Minder about a new sensor under warranty. Surprise-what I thought was a lifetime warranty is really only 1 year, so into the EWaste it goes.
