I tried to install my TST sensors yesterday, i have the flow-through ones. No problem on the front wheels but on the back duallies, I could get one on the outer wheel but not on the inner wheel, maybe my hands are too big. Even if I could get the inner's on, I don't think that the outer one would fit as they would hit each other. It looks like i will need to have the outer wheels rotated to provide clearance. I didn't try to take extensions off. Did you use any tricks to get the inner ones on?
Both gauges read the same and also match another gauge that i have, so I think that they are accurate.
I found that my tires were not inflated per the Ford specs on the door frame (90 psi front, 80 psi rear and 90 psi spare). LF was 80 psi, RF was 90 psi, the outer duallies were 80 psi and the inner ones were 105 psi. The spare was 40 psi!
It was easy to let air out of the inner tires using the release on the gauge and I got a chance to use the Milton 553 air chuck with my 5 gal pancake compressor form Harbor Freight which can only get up to 110 psi. It was great to be able to lock the chuck onto the valve stem and be able to let the compressor run as long as needed. The built-in gauge is very nice and easy to read. The 5' hose, in addition to being a good safety factor (don't stand in front of the tire while inflating) was great for airing up the spare, once I crawled under the truck and connected it, i was able to air up the tire from behind the truck which definitely took a while with that compressor. Next on the list is a compressor that will get up to 225 psi as my trailer tires need 110 psi.
Didn't have any problems getting the cap sensors on the dually wheels after taking extensions off. I also didn’t use the locknut and wrench that was supplied. I have the VIAIR 450 RV air compressor and accessories and it made airing up easy . I still need to get a better air gauge. Air compressor pumps up to 150psi. My back tires are the way they came from the factory, it’s tight but the caps screw on ok.

The Milton lock on how does it unlock if it locks on. Do you need to get your hands on it to unlock or???
Looking to get a F450 soon, question is if I get aftermarket wheels and tires (not commercial) and I add in the BT adapter in those tires does the F450 have the hardware to display the TPMS? Is there a special BT sensor I need for the Ford system?
Ford doesn't use BT based TPMS. The non-F450 Super Duty trucks use a 315Mhz TPMS sensors. Not sure if TPMS can be enabled via Forscan... or if Ford even wired in the TPMS receiver in the F450's.

It works like a air hose quick disconnect, except you don't need to grab the outer piece to lock it on, you just push or pull the chuck to lock it on. To disconnect, you need to pull back (or push for the back facing connection). You can do it with two fingers, so it is not hard to do even in between the dually tires. You can do it through the holes in the stock wheels. It is very nice, locks on easy and doesn't leak air. If you have a small compressor like I do that might take a few minutes to get you up to the desired pressure, it is really nice. I hate the old type where you have to keep pushing on the chuck with one hand while holding the valve open with the other hand, then the chuck slips off of the valve stem a few times or your hand get tired. No 4-letter words needed with this setup

I talked to Brian Nichols about this. He has looked into it. The 450 does not have any options to enable TPMS (its not in the software) and it probably does not have the TPMS receiver. You can install the Ford trailer TPMS sensors and use them with the trailer module but then you can't use sensors on a trailer. I am thinking about getting the TST internal sensors (they are band mounted inside the wheel) and having them installed. If you are putting new aftermarket wheels on, that could be done at the same time. Adding the Ford sensors would also require dismounting the tire and they may not fit the valve stem holes in the wheels.
If the truck does not have the TPMS receiver then where would the TST internal sensors report to? Is there a different display? Agree you would want the trailer tires monitored, but I would wan the truck 1st as I do not trailer that often. Thanks for your help

The TST system has a nice color display (yes you now need something else on the dash). It is expandable up to 110 tires and 4 trailers, so for me that makes the most sense. I think that TPMS on a trailer is very important as I have had multiple tire failures on my trailers over the years and very few on the truck. I will not tow without trailer TPMS any more. I have used the TST B&W system on my old 2008 F-250 and 5th wheel for several years and it saved the day a couple of times. You do need the repeater module to get reliable signals from the trailer tires but that is included in several of their kits now. See: https://tsttruck.com/
Here some pictures of the cap style sensors TST507 installed on my 450 . I left the front valve stem extensions on the front but will probably take them off . It will tuck the sensors back some which will look better. I took the factory extensions off the dually wheels . It’s a tight hit but I can take them on and off ok. Rear outside Rear inside Front with factory extensions still on Front wheel with factory extensions

Thanks for the photos!
It appears that you have had the outer rear wheels rotated so the valve stem do not line up, correct?
I have confirmed that the RV Factory uses the TST internal sensors, installs the repeater and supplies the control unit standard. So my new trailer will be setup when I get it. I am thinking about returning the feed through kit and ordering the internal sensors for my truck as that will solve a lot of problems.
Sensors on my F450 look the same as CWTEX. I have not rotated the rear wheels; inner & outer valve stems in same hole. No problem putting the sensors on; just reach between the wheels. Mine are the old cap style, but I removed the security cover. New cap styles will not have the security cover, they will have a lock nut that you probably cannot use. I don't expect anyone to reach between my wheels and steal the sensors. I have had them on my trucks and RV for several years and have not lost one yet.

OK, i will try taking the extensions off of the rear and see if I can get the flow-through sensors on before I make the decision to return them. It's cold and snowy out today, so I may wait for warmer weather

The flow thru sensors might not work; they are quite a bit bigger. I'm not sure they will do you any good anyway since it is so hard adding and measuring air on these duals.
MontanaHauler, is this the Milton chuck you are talking about? Millton 553
Kind of spendy, but worth it if it works. However, what should I do with all the four letter words I have saved up for use while checking tire pressure and removing hub caps?
