Single piece rims are more like automotive rims where the tire is pulled onto the rim by stretching over the rim's lip. Removal is done by using a tool to get the stretch and removal started. Various tools can work like those shown as long as the tool tip is blunt. A pair of pliers with the arch of the handle works great to get under the tire bead after the tube has been deflated and pull it up and over the edge of the rim. Once done a second tool can be inserted to hold the tire's bead over the rim's edge.

The pliers is then moved to a second close point to continue the process.

With the outside of the tire now over the rim the tube can be pulled from the rim. Now with the tube removed turn the wheel over and push the tire the rest of the way off the rim if you are replacing the tire and tube.

Installing a new tire and tube begins by placing the tire as much on the rim as possible with both beads of the tire inside the rim at the bottom as you stretch the tire partially onto the rim at the top.

Turn the wheel over and pull the tire bead onto the rim.

Place the partially inflated innertube inside the tire on the rim and push the tire back onto the bottom of the rim so both beads are inside the rim. Be sure the tube is on the rim as much as possible out of the way of the remainder of the tire as it stretches onto the rim at the top.

Use your thumbs to press the remainder of the tire the rest of the way onto the rim. If you must use a tool such as a pair of pliers be careful not to pinch a hole in the innertube between the tool and the rim. This is easy to do. Once the tire is in place inflate the tube and check for leaks.
