for many years if i have a tire that the bead has been damaged or has trash in it, bends, etc., try the following. air the tire down, buy a can of Pro Stick 5023 65 Hi-Strength Spray Adhesive ( ) and break the bed on both sides, spray the gel adhesive on both wheel beads only. it doesnt take more than one pass with the good kind above. air the tire back up in under 5 minutes after spraying and you will notice the leaks are no longer. if the air tries to escape right after re-seating, it pushes the adhesive into the void and stops the leak. i have yet* to have this fix fail on a tire yet. car/truck/atv/lawnmower. dont sweat breaking them down later when the tire is worn out. this is NOT ANYWHERE NEAR horrible to deal with as tire slime or fix a flat. that crap makes a HUGE mess! stay away from that stuff.

 

dont buy the cheap liquid style that wally sells. make sure it resembles gel, not liquid. should come out looking like spray web.
