(quoted from post at 20:04:27 06/07/18) Eldon Since those front tires are tubeless I would put a good tire sealer in them NOW. I have it in several of the tractors I use that get thorns and such in them. I am not talking the "fix-a-flat type of stuff. I am meaning a true tire sealer. Reseal is one brand name. Slim does make one too but they make others that are not easy to clean up later. So watch which one of those you get. I use JDs just because it is a good price around me. They will keep the rim lubricated and the JD stuff is water soluble. So in the future if you want to switch the rims or even do a conventional patch on the tire all you need to do is wash the tire/rim with water. This sealer stays a liquid and just rides along until you have some thing puncher the tire. It then seals the leak.
How I would do your front tires is take them off and lay them down. Break one bead down. Then just pour a gallon of the sealer in each tire. Inflate and reinstall, your done. In tubeless rear tires I usually put 2-3 gallons per tire.
You can buy the JD sealer in a Gallon jug with a plastic pump and 5 gallon pails. There is a pump for the five gallon pails too. I bought one because I use a lot of this in Garden tractor tires. It also is great in low pressure ATV tires. You do not have to have a pump if your doing like I stated. The sealer will keep in the jug/pail for a long time. I have a five gallon pail on my pump right now that is several years old. Every month or so ( when I think of it) I just pump a couple of stokes into the pail to keep fresher product in the pump. On a pail in storage just shake it around every now and then.
