A wheelbarrow is a valuable piece of garden equipment, with the capacity to fill many uses around the yard. A flat tire, however, renders the wheelbarrow useless, unable to carry any type of load. Changing the tube in wheelbarrow tire quickly can be the key to finishing a heavy job, so it's good to know how to do it. The inner tube in a wheelbarrow can be changed easily by following a few simple steps.
Turn the wheelbarrow over. This allows easy access to the wheel.
Remove the cotter pin or bolt from the axle. Slide out the axle with a pair of pliers. The axle should slide out easily, but a few light taps with a hammer should loosen one that sticks. Old, rusty axles may require a squirt of WD-40.
Insert the flat edge of a tire iron or flat screwdriver between the tire and the edge of the wheel to break the bead. Separate the tire from the rim in this manner all the way around the tire. Flip the tire over and repeat the process on the other side.
Push the valve stem out of the hole in the rim.
Remove the damaged tube and replace it with the new one.
Put the tire back on the rim and push the valve stem back through the hole. Fill it with air until the rubber touches the rim in all places. The tire can be difficult to keep in place until the bead is sealed, so wrap an adjustable strap or rope around the circumference of the tire to keep it in place until you get a small amount of air into the tube. Remove the strap and finish inflating the tire.
Replace the wheel by properly positioning it and re-inserting the axle through the center. Replace the bolt or cotter pin to hold it in place and turn the wheelbarrow upright.
