Our local tire dealer has a chemical used in mostly commercial tires but will add it to any tires if wanted. When I purchased new tires for my Z-Turn, I had him add it for about $10 a tire. He said if I get a nail or something. just pull it out and I would see a little white "pimple" appear. That would indicate the compound has sealed the hole. Wouldn't you know within a week of putting on the new tires I found a roofing nail in one. I removed it and sure enough, a little white dot appeared. I never heard the first bit of air from the tire and it has not lost any pressure since they were installed. I took the mower back to the dealer and had him fill the front casters as well and hopefully the results will be the same if I pick up anything in them. You guys may want to check with your local dealers to see if they offer this service. Of course I don't think they will hold if you put a big hole in the tire or cut the side wall. Beats the hell out of Slime!!
