Tire Minder power source.

[Against The Wind]

Hello Friends,

We got a Tire Minder i10 TPMS for Christmas and after reading over the installation instructions, I feel they have catered to our neighbors who have a battery outside their rig instead of like ours where the batteries are enclosed. I’m looking for some technical advice as to where I can access a reliable power source to power my TPMS. As always, your good advice is always coveted.

If you’re referring to the little device that relays the sensor signals I installed mine in the front jack housing, there is power in there and room for the module. I repurposed the switch that controls the jack light so that I can turn the module power on and off.

Saw this post from another user...quite detailed.

I mounted the sending unit for our system (not Tire Minder brand) on the outside of our front jack power head.  You can easily pull 12V from the inside of the power head and decide if you want/need an on/off switch for the circuit.

* I just leave mine on all the time...as the draw is minimal.*

We have been using a TST TPMS for several years. I opted to mount our TPMS relay out of the weather and UV exposure inside the main battery compartment with tiny strip velcro. It has worked flawlessly since installation. All I did was attach it to my battery terminals. Keep in mind this relay creates  a very low parasitic draw on your house batteries. Not an issue in my case, as XPLOR is parked at home and always plugged into 30 amp. 

Have fun and mod On!

Additionally you may want to consider replacing your valve stems to the metal variety as opposed to rubber. Rubber ones can fail when sensors are attached.

I spliced a male cigarette lighter plug to my Tiretracker signal booster.  When I tow, I just plug it into a 12 volt plug in the rear of my tow vehicle and temporarily attach it with a piece of adhesive velcro.  One could also plug it into one of the 12 volt receptacles in the trailer.  When I am finished towing I unplug it, lift it from the velcro and store it away until the next trip.

I just had that happen yesterday.

We also have a TST and plug the signal booster into the 12v cigarette lighter outlet above the cooktop. Not sure how the Tireminder works but honestly the few times we forget to plug in the booster, the TST seems to work fine.

We’ve never used a booster for our TST.  Works fine.

Gosh Golley HD.  You need a bucket of Lucky Charms to turn around your bad luck streak!

The reason I initially installed the repeater is it was required to maintain warranty. I am likely well out of warranty now.

That was why I was changing a tire.

I did the same, works great for both trailer and TV tires!

I don't even use tire minders, but I still installed metal valve stems on all 8 wheels of our rig! And when you replace your valve stems, have them balance your wheels with the tire-minders installed (understood the don't weigh much, but why not?). 😎
