How to Change a 20 inch tire
In this tutorial, we learn how to change a 20 inch tire. First, you will need to remove the valve core with a removal tool. Then, rotate the rim until the beat is separated. From here, secure the rim on a machine so it can be unmounted from the tire. After the tire has come off from the wheel, repeat this on all of the different tires. When finished, use the same tool to put the new tire back on. Then, you will need to inflate the new tire that you just placed on. Finish this off by putting back on the vehicle and you're done!
