Tire slime: great stuff

For a good while my tires were getting soft like every 3 days. I had to keep inflating them. With no visible marks on the tire, at first I suspected the air Venturi. But it wasn't leaking there neither. I think my tires are getting deflated from the rims, and I am suspecting it is from taking off the tires with the tire irons that carved a little into the aluminum inside the rim. I used tire slime that I found at ace hardware and I must say, it works pretty good so far.
