How to Change a Dirt Bike Tire
Changing a dirt bike tire is no different than changing a tire on an ordinary bike; though the locale might be different if you’re forced to change your tire while out on the trail somewhere.
At any rate, it is assumed you have a replacement tube and tire, and a means for pumping air into it.
Here’s how it works. You first turn your dirt bike upside down so that it is standing upright on the handlebars and seat.
Next, you use two wrenches (generally ones from a toolkit that came with your bike or was purchased later) to loosen the nuts on both sides of the axle of the tire that has gone flat. You hold one side steady, while you turn the nut on the other side. Loosen the nuts till the tire itself comes loose. Pull it free from the bike.
If the tire is only partially flat, release the rest of the air in it. Once the tire is completely flat, use the tire extraction tool (pretty much the same thing as flathead screwdriver) to remove the tire from the rim. What you do is slip the head under the tire at any point, then slide it in either direction. Doing so will cause the tire to lift slightly. When it does, slip the extraction tool under farther so that it passes all the way beneath the tire, then slide some more; that should be enough to cause the tire to come free of the rim.
Set the old tire and tube aside, then unravel the new tube and lay it down on the inside of the new tire with the air valve pointing in. Make sure there are no twists in the inner tube, then put the one part of the new tire and tube that has the air valve on it onto the old rim where there is a hole for it to pass through. Then string more of the tire onto the rim till you’ve got all but the last part wound around the tire. At this point, use the tire extraction tool to assist you in putting the last part of the tire on the rim.
Next, pump up the tire and then let it sit a while, making sure it holds the air okay.
Then, set the new tire and rim onto the dirt bike into the fork where the old one came out. Tighten the nuts on both sides, test to make sure everything is sturdy and stable, and you should be good to go.
