The idea was born out of frustration, Johnson recalled, when he blew a valve stem in the midst of a large horsemanship event at his ranch.

“For a farmer, if he’s trying to get a hay crop in and rain’s coming and he blows a valve stem, it could cost him thousands of dollars. Twelve bucks for a tire stem? Give me 10,” Johnson said.

He remembered thinking to himself: “If I could push something in there and cause it to expand in a way that was rugged and sturdy, it would be every bit as rugged as a valve stem inserted from the inside.”

Johnson, who owns The JBiT Ranch with his wife Barbara in Berryville, created his own valve stem.

The rest, from the top of the rubber grommet upward, is “standard public domain,” Johnson said - a standard valve stem with a standard core “like in billions and billions of tires.”
