TPMS sensor in spare & night edition wheel for spare

I hope someone will have a bit of insight here.

2020 3500-

First, will an OEM, non-spare wheel work with the wheel hoist? I don’t know why it wouldn’t, but I thought it’s worth asking before I go on eBay and click “buy now”.

Second, would I be able to put a TPMS sensor in my spare, then do a five tire rotation? Or would this fifth sensor hanging out back there, somehow screw with the TPMS?

I’ll be getting new tires in a couple weeks, going with 285/65R20 for the higher load capacity, and I’d like to just get five of them plus a matching night edition wheel, and put my spare into the tire rotation.

Any input on these two points would be greatly appreciated!

Spare tire tpms

Any idea of availability to add tpms to the spare (or spares) using the factory system. Thinking that a dually can read 6 sensors, that functionality should be baked in and enabled through alfaobd or the likes? Looking at picking up one or 2 spare 37's to ride in the bed. I'd like to have that...

I would be concerned with the hoist scratching the wheel up, as well as road debris. If the NE wheel even fits it would have to be mounted with the good surface down. Test it with one of your wheels, but when I’ve looked at it I’ve gotten the impression it won’t work.

As for the TPMS sensor, every time I’ve had wheels with sensors in the bed the readings got funny. It alway read the 4 tires that were installed, but the positions got flipped a couple times (F to R, and R to F). Most the miles were trouble free though. So something to try I guess.

I too will be going to a 285/65R20 on my next set, but I’m not going to bother with the larger spare. Worst case, if you’re loaded that heavy, is you can put the spare up front and have the higher LI tires on the rear axle until you get to a shop.

So, looking at the hoist set-up, there would need to be some sort of rubber grommet added between the hold down and the wheel, or it would significantly scratch the "hub" looking part, where a ram center cap is mounted.

Also, whipping out my trusty measuring tape after getting under there and seeing the clearance the tire has... I am seriously skeptical that a 285/65R20 would even fit in the stock location. It's about 1-1.1" larger in diameter, and there seems to be about ⅜" extra clearance front to back. The exhaust heat shield leaves almost no room to spare.
I'll be getting four tires, then testing to see if one would even fit in the location, before even considering getting a fifth.

I would like to run all tires the same diameter, including the spare, as the difference is likely not a good thing for the friction disk type limited slip in the rear. But, if it won't fit in the spare tire location, there really isn't much I can do. When I get the factory spare down, I'll at least be able to look and see if perhaps the heat shield can be shifted out ½". There's room on the other side of the shield, but I don't know if there is room in the attachment, such that the holes could be slotted out to allow the shield to slide out a bit.

Yes.

I have had my OEM tires at 100% a couple times, so a higher LI isn’t a bad thing.

Same here. I'm typically right at GVWR when towing my 5th wheel (sometimes a bit less, sometimes a hair more depending on the load I carry in the garage, and where my water is located). That extra 880lbs on the tires load capacity would be a margin of safety that would give me more comfort.

Plus, I figure, my SRW (11,800 gvwr) is the same frame and same axle as the DRW (14,000gvrw). So logically speaking, the truck should be WELL capable of another 880lbs of load.
 
Does anyone else have issues with their TPM factory valve stems cracking after a tire pressure check at home?
