Review: THIS IS WHAT YOU NEED! WORKS PERFECT. - QUALITY TIRE TUBE, EASY TO INSTALL, HAS NOT LEAKED. VERY DURABLE.
Review: Mongoose - Mongoose brand tubes. Good thickness, most importantly, reliable quality control. If your buying 20x4 tubes buy these ones and an 8oz bottle of slime per tube. Use your old tubes as tune liners by cutting off the old valve stem and slicing the inside circumference of the old tube. Making a shell that your new tube can wear. Put one side of the tire on the rim then Insert the liner you made with the old tube into the tire, then put in the new tube, starting with the valve ste. Slightly inflating the tube once you have the valve stem in makes it easy to go around pushing the tube into the liner)tire. Once you have it all in there go to the stem part and now press that part of the tire into the rim go around with your left and your right and before they meet at the top of the rim you will get to a point where the tire needs to stretch a little to get on the rim the rest of the way. This is where you use your tire levers to pry from outside inward, being very careful that the top of your lever is against the metal of the rim not the rubber of the tube. Get one lever put in place and hold it there while you get the other leaver to do the same thing on the other side of the stretch, with both sides on levered like that the remaining part that needs to stretch will be shorter. Just press it inbwith your finger. If you can't then squeeze the tire where one of your levers is, so it doesn't come off when you remove it's lever, and use the lever to pry the remaining bead into the rim . Being careful not to pinch the tube. Once is on the rim completely pump it up.
