Then, stand the wheel up (rest it against your shins if needed) so that the valve hole is on top, and hold the tire/tube over the wheel so that the valve is on top. Inflate the new tube just enough to round it out and remove any wrinkles, and place it inside the tire. If you can't find anything, it's likely it got knocked out during the disassembly procedure. If something sharp is still stuck in your tire, it'll snag the glove. If you don't, the culprit might still be in the tire where it'll just pop your new tube! To find it, remove your glove (or use a rag), and run it around inside the tire in both directions. It's important to find whatever caused the flat and remove it.
Pull the other side of the tire off the same side of the wheel or pry it off with the levers. Then reach inside and fully extract the tube. Continue with your third lever until you can get one side of the tire off. Place another lever about 4 inches away from the first and pry here.
If possible, hook the lever on a spoke (many levers are made to do this), or hold it in place. Starting directly opposite the valve, wiggle a tire lever beneath the tire's edge and pry down to lift. For Schraders, poke the end of the tire lever into the valve to release all the air. For Presta valves, unscrew the tip and press down to let all the air out. Remove the valve cap and nut sometimes found on Presta valves. For fronts, you'll probably need to hold one side of the quick release and turn the other counterclockwise to create clearance to get past the wheel-retention ("safety") tabs on the fork. To extract rear wheels, it helps to pull the derailleur back slightly to clear the axle parts as the wheel passes through. Open the quick release (or loosen the axle nuts) on the wheel with the flat and lift the bike to remove the wheel. Open cantilever brakes (these feature a cable that runs over the top of the tire) by lifting the cable end on one side out of its holder. Look for this if there's no lever on the brake.
Some sidepulls are opened by pressing a button on the lever. Open linear-pulls (also called "direct-pulls" or "V-brakes") by lifting the end of the "noodle" out of its holder. Open sidepull brakes by fully rotating the little lever on the brake upwards. The first step in wheel removal (except for bikes with disc brakes) is opening the brake, which makes it easier to get the wheel out. If it's a rear flat, shift onto the smallest rear cog. Note that, while we've tried hard to answer every possible question you could have about flat tire repair, you only need to read as much as you want.Īs soon as you get that "sinking" feeling or hear the hiss of escaping air, let your ride partners know you have a flat (so they won't disappear over the horizon) and stop in a safe spot. Here are complete instructions for each of the simple steps to fixing your flat tire.
