    I was thinking about filling my caster tires on my walk-behind with Great Stuff (that super-expanding insullation foam at hardware stores). First I would remove the valve core and then fill the tires, allow it to expand, and replace valve core (possibly inflate to increase pressure). My hope would be that this would make these tires completely flat proof. I realize that this is either a Great idea or a terrible one. P.S. I have already tried fix a flat with no improvement on one tire.

    might are you gonna get the stem back in though? stems are installed from the inside of the tire. the caster dont usually have much weight on them so it should be fine. it aint gonna cost bu $5. try it and if it dont work order the real no flat casters from your dealer.

    You may as well run them flat, because the "Great Stuff" is just going to crush to powder once it sets.
    We're replacing all of our caster tires with solid rubber ones as they wear out. Just a thought.

    I have slime in the tires of both ZTRs we run. It works really well. I wouldn't think that it would be too expensive to slime those small tires.
