how to change dirt bike tire
Step-by-step guide to changing bicycle tiresDuring my most recent tire change, I decided to do a tutorial on how to change a dirty bike tire at home. Changing a bicycle tire can be a daunting and avoidable task for most riders, but with the right tools, it can be done just as easily and is no more difficult than changing the oil. I’ve owned dirt bikes for a long time, I change my tires all the time. I was too stubborn to pay a shop and I’ve always wanted to work on my bike myself. I remember buying my first set of tire irons and quickly destroying the tubes in the first few tire changes and cursing myself that it would be cheaper to take it to the shop. And don’t think twice about it. It’s great to be able to mount your tires as soon as they reach your door, or swap out used tires for different trips, or flip the tires around to use the sharp edge on both sides of the knob. . Here is my step-by-step guide to changing dirt bike tires, from disassembly to reassembly on my 2014 KTM 450 SXF, to a Dunlop Geomax MX32. handOver the years, I have amassed the tools needed to change a dirty bike tire. I started with the 2 curved tire iron and then the 3 spatula after learning a few tricks to make changes easier. After struggling and thinking “There must be an easier way to do this!”, I figured out how to use the Bead Buddy, the tire puller, the tire change lube and finally the specialist tire holder. use. Here is a post where I talk about all the tools I use.
Tires and tubes
Contents
The tires that I am changing and fitting are all Dunlop Geomax MX32 front tires. I’ve had and put more around that only had a few races on them. I am also reusing my Bridgestone Super Heavy Motorcycle Tubes. Some of the other items are Rim Tape, Children’s Powder and Tire Lubricants. I ended up using some black tire spray to attach the lubricant to the pin, but you can buy a specialized lubricant to use on tires and also use cleaner window, although it evaporates quickly and can sometimes dry on you.
Removable wheel

To remove the front wheel, place your bike on a rack or lift to lift the front wheel off the ground. Remove the shaft nut, then loosen the 4 pivot pin bolts. To remove the shaft, you can use a T wrench or an extension ratchet to push the shaft through the fork lugs.
Disconnect the inner tube and lock the rim
After placing the wheel on the tire rack, you will need to deflate the tire and disconnect the tube and lock the rim. Use the valve core tool to pull the valve core out and keep the rest of the disassembly. Remove the core so that the inner tube is fully compressed. If you just deflate the tire by pressing on the valve, the inner tube will still contain some air and will make it harder to remove the tire. After removing the core, remove the valve nut. For the rim lock, you just need to re-tighten the nut but don’t remove it. Once loosened, press down on the rim buckle to make sure it moves freely.
Break the tire bead from the rim
Now you are ready to remove the tire. The first step is to pop the tire out of its bead. What you are trying to do is drop the tire’s bead in the center of the rim. The rim is U-shaped and by dropping the bead in the center it allows the tire to move, so you’ll have a bit more space to pull the bead out to the outside of the wheel. Start by loosening the tire near the rim lock. Hold down the rim lock so the tire can slide backwards. You can spray some lubricant on the tire if it gets stuck.
Raise the tire over the rim
This is the hardest part to change a bicycle tire. Use plenty of tire lubricant and take your time and work on small sections at a time. Spray a generous amount of lubricant on the tires and rims and start with the tire at the rim lock. Place tire irons about 4 inches apart and work one small section at a time. Getting over the first part of the tire is the hardest part, but once you continue, the rest of the tire will slide right away.
Wheels pull over tires
With one side off, flip the tire over and repeat. You want to pull both sides of the tire to the outside of the wheel. When both sides of the tire are on the outside of the wheel, push the wheel down in the tire and pull the wheel over the center of the tire.
Check inner tube, rim tape and rim lock
Check to make sure the rim tape is intact and not broken at any point, dirt can get into the tire and act as sandpaper on the inner tube while riding. With a standard tube, you should change the tube after every tire change. With extra-heavy inner tubes, you might be able to change the tires a few times before they thin out. I ride Bridgestone heavy duty tires and usually go for 3-4 tire changes before changing. The inner tubes wear out like tires and begin to stretch and thin after hours.
Inner tube and tire preparation
Clean the inner tube and make sure the tire is free of sand or other debris. If you are fitting a new tire or reusing an old tire, a good tip is to sprinkle a little baby powder on the tire before adding the tube. The baby powder will act as a dry lubricant between the tire and the inner tube, and help with rubbing and friction to thin the inner tube. Add a small amount to the tire and rotate the tire around to spread evenly. Also, you will notice on the tires there will be a mark, a yellow circle in this case. This marks the bright side of the tire. You should place this marker near the stem of the valve and lock the rim.
Put the inner tube on the wheel

This tool is quite cheap and will save you some effort. Once the valve body is pulled through, tighten the valve nut to hold the spool in place. Then reinstall the valve core.
Put the tire on the wheel
Mounting a car tire is a little different than removing it when you’re changing a dirt bike tire. You can get half a tire by using a 2 curved tire long iron. You will want to place the tire bead between the rim lock and the rim. This allows the tire bead to be in the lower drop center, which helps the tire to be pulled up. You can force most of the tire on the wheel using the tire rack, but the last part I find easier with placing the tire on the ground and using your knees to hold the tire in place. Reach for the curved end of the tire iron and lift the last section over the rim.
Attach the rest of the tire
This is when having a beading buddy and a good set of tire irons comes in handy. Starting from the rim lock, push the tire down to the center of the wheel. Make sure the rim lock is not out of place and keep the tire down with a friend. Work around the tire with the tire iron in small chunks at a time near the end. The last part is always the hardest so use lots of lube and do it in small portions.
Inflate the inner tube to place the beads
The final steps are to tighten the valve stem to inflate the inner tube to place the nut. You’ll have to over-inflate the tire for the bead to “pop”. You can run a finger around the edge of the rim to feel that the tire is fully seated. Once the nut is in place, deflate the tire to 12-15 psi and tighten the rim lock.
Mount the wheel
The final step to changing a dirty bike tire is to install the wheel. Pretty straight forward but with a trick. Use a flat-blade screwdriver to spread the brake pads. This will keep the fork from spinning while you try to stack the brake discs. Read more: how to pluck chicken feathers by hand.
