So today I decided to task fixing the outer dual flat on my drop side. Everyone knows what a pain these things are to break down. I have a mechanical bead breaker that you screw down on the rim the crank the bead loose. You have to do this in about 4 or 5 spots on each side to break it down. After 30 or so minutes, I get the thing off the rim. Pop out the flap and tube and cleaned out the tire. This thing was flat for a couple of months and once I had to do a swamp recovery so it was full of crap. Got it cleaned out, new tube installed, flap inserted and all put back together. Aired it up and down a few times and put the core in. That's when I realized it was still leaking air. CRAP! Mistake #1. I failed to follow my own credo of checking the inside of the tire fully. Took it all back apart and low & behold there is a nail still stuck in the tire. Patched the tube, pulled the nail and reassembled. Victory this time. I tell you all this because I didn't do what I preach. Follow these simple steps. Mark the valve location on the tire. Pull it all apart and check the tube for holes. Once you find them, match the location up with the tire and check it really close in that area for debris in the tire. Had I done this I would have found the nail. Cleanliness inside the tire is imperative, wash it out, wipe it out and vac it out!
