I have a wheelbarrow with a 15 inch tire. It was flat so I used my compressor, unfortunately the stem popped out due to the rubber. Corrosion. I've never replaced a stem in a tubeless tire but decided to give it a try as it's not worth replacing the same type of tire considering how often it's used. Took out the old stem, measured the hole size and ordered this item as it said it was the size I needed. Had to pry back the tire near the hole which was a little tricky as it was a tough old rubber
