I know theres been a lot of discussion on why theres no TPMS on the F450s. I personally dont think its bc of the steel in the tires. I say this bc i purchased 19.5” wheels and tires for my 18 F350 and the company I purchased them from tried to sell me TPMS sensors with the wheel and tire combo. Meaning the TPMS sensors would work thru the 19.5” commercial grade tires. I opted for no sensors and turned off the TPMS system in my truck via ForScan.
I believe F450s dont come with TPMS system bc then what does Ford set the sensor range to? 70psi - 110psi? Thats a huge range. Many run their 450 19.5” tire pressures lower when unloaded for better ride quality. If the pressure range is set to 90-110psi, then many would dislike the harsh ride at those higher pressures. Most of the SD TPMS pressure ranges are 15-20psi. Like my stock 350 tires, below 50psi and the light comes on, 70psi is the max per the door sticker. 20psi range.

GVWR being the reason is not it bc the 350 & 450 have the same GVWR and the 350 comes with TPMS.

TPMS works with 19.5” per the wheel&tire company i purchased my 19.5” wheels& tires from. So its not bc 19.5” tires are not able to pass a transmitter signal.

Its not bc the front axle is wider putting the sensors too far from the receiver bc the rear tires are much farther away from the receiver then fronts.

This leaves the only difference or variable between the 350s & 450s is the amount of pressure in the tires.

 

I am going to call you more right than wrong for sure. There is no shortage of NON steel belted 19.5 tires on the market and the reasons why the 450 is speed limited is because of the steel tires. They are incredibly heavy. IF Ford really wanted to do something the dually rims would come with some valve stems that are usable. I just coughed up $100 per tires to install long valve stems on my inner tires and then, of course, they had to be balanced, $20 for the stems installed and $80 to balance. First that is crazy, it costs no more to balance a 19.5 rim than it does to balance any other rim. The rims are not unique, they are a standard rim only a 19.5. The Conti's run about $400 per tires drive out, yet there are many other 19.5 that run far less than $300.

I am a fan of TPMS, I use it constantly on my F 350's, it should be on my 450!

 

I used the TST cap sensors. You must remove the small extensions (1.5in?) that Ford puts on before installing them. It is helpful to have the rear stems at 180deg from each other. That inside wheel is a bit of a PIA but doable even with Centramatics on.

I used TireMinder and find the TST much more user friendly, especially the color version. It's very easy to "drop" the trailer and have just the truck register. You can also setup with multiple trailers as well.

 

 

Thanks for the links! I must have looked right over your original post with the info you posted when I asked the question lol.

 

Whatever the reason, F450’s do not come with TPMS. No, I had to remove the OEM extensions. No, my rear stems came mounted on same side of wheels. I just reach between the duals and screw the sensors on, they fit fine; if you have old style TST sensors remove security cap.

 

I have a 3-year old B&W TST system that I used on my 08 F250 and 37' Montana fiver. I do not have the repeater and a few times when towing in the rain, the trailer sensors were not picked up. Replacing the batteries helped, but I think that the repeater is a good idea. It comes with the new kits. The instructions now state that the flow-through sensors need to be used only on metal valve stems, a lesion I learned the hard way. Other than that, the system worked well on an Alaska trip and a few other shorter trips.

I was planning on using the Ford trailer TPMS system on the new Luxe trailer that we are ordering, however it comes with 17.5" H rated tires and I am not sure if they are steel carcass, if they are, the Ford internal sensors probably will not work, so maybe I will just get a few more TST sensors and upgrade to the new color display with the repeater (the new trailer will have 6 wheels).

One tip on the TST sensors. Buy extra batteries on Amazon. I bought some in Whitehorse in the Yukon and had to pay about $6 each. Amazon cannot ship lithium batteries to Canada.

 

TST internal sensors DO work with steel construction tires (2017 F-450 with factory Continental HSR tires.). HOWEVER, you really need to use the repeater.

 

Same here got a 2020 450 and a triple axle I’m supposed to pickup mid March . I think I’m going to order the TST 507 system with 12 cap sensors. Later on I may pickup a couple of flow through sensors for the spares.

 

Hold the phone! So you're saying that I can mount sensors inside my wheels and they work? Why would Ford not mount them?

 

There has been a fair amount of speculation on why Ford has not addressed this. I don't have anything to add.

Indeed, the TST internal sensors DO work. I found the display unit needs to be within several feet of sensors mounted inside the Continental HSR...hence my comment about using the repeater. I discussed this application with TST and they confirmed it works.

I have not used the truck much since the internal sensor install and need to permanently mount the repeater ...so this has not passed "the test of time". My guess is it will be just fine.

 

Been reading yays and nays on this for a couple of years, but what I have not seen is a for-real install with a write up and a post-install report on a 450 dually with 19.5 OEM tires. Also the total cost of this. I just had my 2 inside tires, replaced the valve stem with one that could be reached. So 2 insider tires, new valve stems installed $20 bucks @ + balance @ $80 bucks each total = $199. I think I got ripped off, dunno, never had 19.5 rims balanced...did I???

 

They don't work with Ford's TPMS systems. There are TPMS systems that work with medium duty tires used by HD Trucks, but they generally require repeaters due to the week signals caused by the steel carcass tires. Ford has obviously chosen a one-size fits all of their vehicles and didn't want to invest in what it would take to handle the F450+.

 

Last fall, I had the Ford TPMS sensors installed in my trailer tires in anticipation of being able to use them with the Ford trailer TPMS system. The tires are Goodyear G614s which I believe are steel carcass. However, until I receive the correct TPMS kit from Ford for a 2020, I will not be able to see if they work. I got the sensors installed for free as I was replacing the tires at the time.

I couple of years ago, I had a valve stem (rubber) fail on my trailer because of the weight of an external TPMS sensor. I got all of the valve stems replaced with metal ones at a Les Schwab dealer for $15 each, I thought that was a good deal.

We have another tread going on the Trailer cam/TPMS wiring problem and there is more info there

Not sure where you would even place a repeater seeing the display/ receiver would be sitting between both axles. Mine is still sitting in the box. I just used the screw on ones and they suck to install.
