Yeah those Colby Valves seem to be pretty cool
The guy named them after his grandson if I remember correctly

 

Was watching a YT vid from a fave Aussie offroader, and that led me to:
Colby Valve - Tire Valves, Automotive Parts

And:
CV Emergency How to 1080p

Interesting product for sure. Thanks for sharing.

I’ve tore off a couple valve stems in the past and had to break down that area of the tire to fit a new one. It’s not hard but definitely a pain on the trail.

I’d typically just put on my spare and then fix the stem at camp that evening. That emergency style stem looks like a much faster solution. 👍

 

I've seen people just use a funnel tool to change the valve stems from the outside too. Seems to work reasonably well. AME is the company I believe.

 

What a great product. But what about the rest of the TPMS inside the wheel. Bet that sounds great plus throwing it out of balance. 60 years of driving I have never lost a valve stem, but I am new to off roading too.
The Colby will get you back to town. i would say a mus have for a many days excursion.
Luck

 

I deleted TPMS so luckily it simplifies my situation.

My issues with valve stems in the past were from rocks or tree limbs ripping the rubber which caused a leak. It actually took me a minute to diagnose the valve stem being the problem.

 

I wonder if they have TPMS for riding lawn mowers!

That, along with an enclosed air conditioned cab you can bolt on.

If I make my mower comfortable enough, maybe I can get my wife to start taking care of all the mowing!
