Off-road valve stem replacement

I did this. I'm making a how to video to show people what to do.

To sum it up;
took out the Schrader valve, used a high lift jack to break the bead and press the tire down far enough to insert the new valve stem from the inside. Used a co2 / compressed air tank to re-inflate the tire (pop the bead back on).

I'll post the video in a few days.

 

Out today in my 2018 on a sketchy sideways area of the rocky trail a rock sheared off the valve stem. The metal TPMS stems do not have any flex at all. I'm looking for a solution but it looks like all the low profile or the easily field replaceable solutions are for the rubber valve stems not the rigid TPMS sensor stems. Now deciding if I'm going to just remove the TPMS sensors since it only came on most when it was cold or driving up.to.colder high elevation and almost always was the spare. I have an on board air compressor so checking and setting psi is no big deal.
Does anyone have any low profile stem options and field repair from the exterior options or recommendations.

 

I bought the Colby for trail repairs. I haven't used it but it should work for our stems. AFAIK there aren't different requirements for the hole in the rims for TPMS.

 

I'm assuming with the TPMS sensor you can just undo the 12mm exterior nut then let the sensor just bounce around inside (probably ruin it) then nstall the field repair one from the outside. This way you don't have to break a bead and just repair it when you get home.

 

Yes.

I'm also pretty sure you can't separate the stem from the sensor, so once the stem is broken the whole thing is trash anyway. Doubt having the broken TPMS bounce around inside the tire would do any damage. At least not until you could get it repaired.

 

I saw a youtube video of this guy who had this magic device that was from the 1940s or something. Looked like some sort of brass "marital aid" type device but it was an air powered valve stem tool. It was cone shaped on one end so you stick a conventional value stem inside the cone, and the cone squeezes the stem into the tire. No tire removal.

But there are commercial replacement stems out there that you should carry.

Those Colby ones are available on Amazon now.

It could certainly throw the tire balance off, so I'd take it slow, but this would definitely get you off the trail.

 

Colby valves are totally the way to go. They're cheap and take up no space. I always have one or two in the truck. And I know they work because I've seen one in action.

 

Yeah, the video I saw, I can't remember who or where, but it was definitely a cool tool. It was one of those "guess what this thing does". Totally cool, but in the end, totally obsolete since these Colby valves came out.

 

I think I'm going to install the permanent Colby Valves and have some as a spare. I plan on putting the registered TPMS sensors in a pressurized PVC tube I make to trick the computer so the light goes out. Some guys I know did that. With the Colbys you don't ever have the problem of a rubber ball or a TPMS sensor remaining in the wheel that you then have to take out. Colbys are expensive but cheaper than TPMS and low profile and you can't beat how easy they are to change.

 

Something like this might work too. Then you don't have to carry around a PVC pipe everywhere you go.
