Colby valve stem TPMS

What type of tpms sensor does a 2020 sr5 have, and will the Colby work as a emergency replacement for the valve stem?

 

I don’t know for sure, but I would think worst case you would jam a screwdriver in there and bust the double sided tape holding the TPMS. I carry two Colbys but never used them yet.

 

Any other thoughts?

 

The sensor is not mounted with double sided tape. It is a nut and sleeve.

 

Does it keep you from using a Colby stem?

 

To get the sensor out, the tire bead has to be broken loose from the wheel.

 

Well, that certainly cancels out any usefulness of the Colby stems, doesn't it.

 

The Colby can still work from what it looks like. I've never used it but I did just change my TPMS on my own. If this video is really how it works then you should be ok.

You will just have the sensor banging around the rim until you can get it out.

 

So you would just take the outer nut off the TPMS, push the stem in, insert the Colby and leave the inner part of the TPMS loose in the tire till you can get somewhere to remove and repair the tire? That sounds ok in an emergency.

 

Yes just remove the nut. I think it was a 10mm but if it breaks guessing pliers or something will have to do its not on there super tight.

And just push whatever is left of the stem into the tire. It will just be banging around in there. The sensor part in the tire isn't held on to anything the nut holds it in place.

 

Thanks for the info

 

Do you think the sensor would break if it was loose in the tire for a little bit?

 

I would replace it. It might work for a little while but who knows.

But I do know these work. This is what I used when I did the TPMS on my own in my Tacoma. If you want cheap.

Breaking the bead on factory tires isn't so bad. But I can imagine it being painful with LT tires.

 

Yes, plan/budget for the sensor to be destroyed if you push it into the wheel.

You can break the bead with the bottle jack, remove the sensor, then pop the bead back on with a flammable aerosol. However, this is slower than swapping in your spare tire.

 

I found using a scissor jack was better.

My bottle jack would max out before the bead would pop. I figured using 2x4 under the tires or something was more of a pain in the ass than just using a different jack.

I also saw a guy using a 4x4 and he drove another car up it to break the bead.

 

But if the valve stem is damaged enough that you have to replace it with the colby (in an emergency) then you would need a new sensor anyway, right? Since they appear to be one piece?

 

Yes pretty much. The stem is solid so if you ever broke that you need to change the whole thing.

 

It depends on the model year. The 2020 and newer are a little different....same on the Tundra side. The newer models don't like most aftermarket sensors.
