What?!?!?!?

I know they are cheesy screw on to the valve stem ones, but I was gonna use the big zip tie (like ford uses) to secure it to the inside of the rim. Anybody else try these things?

Using a zip tie to secure the sensor to the drop center portion of the wheel would cause some difficulty in tire mounting. Many many times ford techs would break the band or the sensor. The idea of having the sensor as a valve stem cap is not a terrible idea. However, I feel as though the caps would look too big and out of place.

Yeah, but its so chinsi or cheap looking. Also, I'd be afraid that it'll develop a leak and bleed my tire pressure down.

I got a set already as a test. The RX7 is gonna be the Guinea pig. I am either going to use the big zip tie you get from Auto-zone to repair the ford big metal zip tie, or I am just going to wrap the whole hoop with tape (I've "fixed" ford tpms this way before). Another option I was thinking about today was to use a "207" style TPMS kit and affix the sensor to the 207. Honestly The 207 is more than likely the route I'll go.

Well, I got them in the mail. Just strait up twist them on and go.




I put them on my wife's car for a trial till I figure out how to mount them to the inside of the valve stems. But to be honest depending on your wheel design and color you can't really see them at all. I'm gonna order another set at minimum; might even go full bore and get a set for every car.

I cut a hole in the brass extension on the bottom of the 208 TPMS kit (I guess I used a 213 in this case). Zip tied the cap to the hole. Done... I'm gonna install them in the 7 as soon as my second set comes in the mail; I like having these on my wifes car.

So how did it turn out zip-tied on that way?

I was using these on my FD a few years ago but I kept having issues with one of the tires losing air while I was driving. The only thing I could figure is that the rubber valve stem wasn't strong enough for the extra weight at the end of it and it would leak due to bending. As soon as I switched to an internal set (that also came with metal valve stems), I never had any more issues. Not with air loss anyway. After a couple years, the receiver stopped working. Both sets came with the receiver/gauge that plugs into the cigarette lighter port. One of them just died completely and I swapped to the other one but it eventually failed too.

Now I'm looking into using a set through the Joying Android head unit I just installed. Joying only offers the external sensors like these and I want to keep using internal sensors, specifically ones that allow battery replacement if possible. The internal sensors I used with the cigarette port version have replaceable batteries, but I can't find a way to read the codes on those sensors so I can reuse them in another system. I did find only one other set with replaceable batteries, from another Android head unit company called T'eyes. I bought that kit, but I'm having issues getting it installed on the Joying so far.
TEYES Tyre Pressure Monitoring System

I actually tried doing this a couple years ago already. I found a set sold by Phoenix Automotive, they claimed that the batteries were replaceable and that it would work with android auto, because until recently I was using a Pioneer AVIC-8100NEX. Once I received them, I realized that both of those claims were lies, and the company basically left me in the lurch when I tried to return them. I did install that software and it looks like those sensors would work, but I'd like to still use the ones from T'eyes if I can. Or maybe I'll just use the Phoenix kit for now.

Does anyone know of a tool that can read sensor IDs on these types of sensors? I have yet to see any identifying marks on the sensors themselves.
