I was out cleaning up my wood road and pushed back a tree top when a limb flipped over and knocked out the valve stem from the back tire of my jd compact ,fluid started blowing out so I drove back to where I could get it jacked up and stop the bleeding. I didnít know how I was going to fix it. So I slept on it and the next day I talked to a friend of mine who does tires . I found out that they make a valve stem that goes in from the outside so you donít have to break the tire down pump the ballast and all that goes along with it. I couldnít find one locally,but my friend told me that he had luck putting a regular tubeless valve stem in without breaking the tire down.you just lube it up and work it in with a small screwdriver and after a half a hour of work it went in with no leaks. I forgot to mention I filled it up with beet juice.
