Have seen video of folks spraying the expanding foam into tires to make them usable. This is off the Gurilla cart. Wheels are about 4 years old. Did not know such little tires ever had tubes in them anymore. Saw a couple of videos on youtube where folks just drilled a few holes in the tires to release the air, and to have a few points to put in the foam.
Letting it set up till tomorrow hoping 20 hours will be a long enough cure. I realized it was going to way over expand, just not quite this much. Used the whole can, cuz the manufacture even states, you will find it very difficult to ever use again. What I was not smart enough to do was plug the 3 drill holes and the valve stem hole. I think if I had done that, the tire would have been much firmer. I think it is going to work, just believe if the stuff had not been able to escape, it would have made the tire much stiffer.
Pretty sure a new tube would have been at least $10, and new tire maybe $20...This can was of Great Stuff was under $3 with tax! I guess we see tomorrow if it works!
