I did not know that about Slime. I used Slime in one of my tractor tires several years ago and never thought anything about leaving it in there. When I finally had to change the tire, I discovered that it corroded the rim pretty bad. I will never use slime again. By the way, you make mounting a tractor tires look easy. I struggled with mounting mine, and I even had the tire sitting in the sun for awhile to make it more pliable.

If someone tells me that they put Slime or Fix A Flat in their tire, I tell them to go to another shop. I change motorcycle tires. I don't get paid enough to clean that crap off of my tire machine after the job.
