Has anyone heard of or used these Valve Stems?

[SGT ROC]

I am thinking about getting some of these https://smile.amazon.com/Colby-Valve...C7XP21ED0P4KT3 when I get my TPMS system (have not yet decided which system I want). From the reviews on Amazon, Youtube videos, and other web sources, they seem to be a really good way to get metal Valve Stems. They make them for no tool emergency repairs, 1" and 1.5" lengths, .453" and .625". Thoughts?

The Colby Valves are designed to be a roadside repair valve stem for off road enthusiasts. The way they seal on the rim is by using an expanded rubber wedge. This works well for (relatively) low pressure applications. I would question whether or not they could effectively handle the high pressure tires used on RV's (80 - 110 psi range) especially with the added weight of the TPMS on the valve stem spinning at road speed. You could contact Colby directly and get their opinion. Not sure I would trust other opinions. Too many "I haven't had a problem yet" opinions. YMMV...

According to their FAQ page as to pressure "In testing, the Colby Valve held 3,000 psi indefinitely. So, it's safe to say that if you're using it on a wheel, as intended, you can safely run at standard pressures up to 150 psi." I have a question in to find out about using TPMS Cap sensors. They do claim to be 20X stronger than a rubber stem, and not easily torn or damaged in rough use, as in off road and rock climbing. I'll post a response from them.

According to the question and answer on AMAZON " Question:Can you mount a tpms cap sensor on these, such as tireminder, or tst?
Answer:Yes standard Schrader valve cap size

Yes, although if your wheel allows for it(valve opening isn’t to deep), we would suggest the Ultimate Valves for a lower profile

They have a pretty good review rating on Amazon from what I can tell...

This is the reply I got from Colby. I'm posting my Question and their reply.

Question: Can TPMS cap sensors be used with these valves, such as from EEZ TPMS or Tireminder to name a couple

Answer: I know Tireminder is compatible, as I’ve had customers tell us they have recommended us , I am not familiar with the other brand, but I can see no reason they wouldn’t work.

I would recommend however, if compatible with the wheel type, to go with the Ultimate Valves rather than the Permanent, as the shorter length can keep the cap from sticking out so far.

In looking at my wheels, even the longer one would be OK, as the stem points toward the center of the wheel, not outboard. Therefore it wouldn't stick out past the tire and hit anything. I think I'm going to get a couple of the "Ultimates" and see how they look.

Since you need to dismount the tires to fully remove the original rubber stems, why not get standard proven metal stems like these (which I installed on my trailer rims)?

According to all of the information I have seen, including the manufacturer and you tube, even if you cant get all of the valve stem out, that little piece left inside the tire will not hurt anything.

If you like random stuff running loose inside your tires, fine. I prefer not to.

Do you have 15 or 16 inch wheels?

15" six lugs. These stems will fit two different standard size holes.
