How to Change a Tire on a Mountain Bike [A Step-by-Step Guide]

Last Updated on August 26, 2025 by Jaxon Mike

As an avid mountain biker, I know firsthand how frustrating it can be to get a flat tire while out on the trails. But don’t worry, changing a tire on a mountain bike is a skill that every rider should have in their toolkit. In this comprehensive guide, I’ll walk you through the process step-by-step, so you can get back on the trail and keep shredding.

Assessing the Situation

The first step in changing a tire on your mountain bike is to assess the situation. Take a good look at the tire and determine what caused the flat. Was it a puncture from a sharp rock or thorn? Or did the tube simply fail due to wear and tear? Knowing the root cause will help you address the problem effectively.

Checking the Tire for Damage

Once you’ve identified the issue, it’s time to take a closer look at the tire. Carefully inspect the surface for any visible cuts, gashes, or foreign objects that may have caused the puncture. If you find a large hole or significant damage, you may need to replace the tire entirely.

Preparing to Change the Tire

Now that you’ve assessed the situation, it’s time to gather the necessary tools and materials. You’ll need:

• Tire levers
• A spare inner tube
• A patch kit (just in case)
• A small hand pump or CO2 inflator

Once you have everything you need, find a clean, stable surface to work on, such as a picnic table or the tailgate of your vehicle.

Removing the Tire

With your tools and materials ready, it’s time to start the tire-changing process. Begin by deflating the tire completely, then use your tire levers to pry the tire off the rim. Be gentle and take your time, as you don’t want to damage the tire or the rim.

Removing the Inner Tube

Once the tire is off, carefully remove the inner tube. Inspect the tube for any visible holes or punctures, and determine if it can be patched or if you’ll need to use the spare tube.

Preparing the New Tube

If you’re using a new inner tube, make sure to inflate it slightly to give it some shape before inserting it into the tire. This will make the installation process much easier.

Inserting the New Tube

Carefully place the new tube inside the tire, making sure it’s not twisted or pinched. Start by inserting the valve stem, then work your way around the tire, pushing the tube into the tire’s sidewall.

Reinstalling the Tire

With the new tube in place, it’s time to put the tire back on the rim. Start by hooking one side of the tire onto the rim, then use your tire levers to work the other side of the tire over the rim. Be careful not to pinch the tube as you’re doing this.

Inflating the Tire

Once the tire is fully seated on the rim, use your hand pump or CO2 inflator to inflate the tube to the recommended PSI range, which can typically be found on the tire’s sidewall.

Finishing Touches

After the tire is inflated, give it a final inspection to ensure the tube is properly seated and the tire is securely in place. Spin the wheel to check for any rubbing or irregularities, and make any necessary adjustments.

Conclusion

Changing a tire on a mountain bike may seem daunting at first, but with a little practice, it becomes a relatively simple task. Remember to always carry the necessary tools and supplies, and don’t hesitate to ask for help if you’re unsure about any part of the process. Happy trails!

FAQ

How often should I check my mountain bike tires for wear and tear?

It’s a good idea to inspect your tires before each ride, looking for any cuts, punctures, or signs of excessive wear. As a general rule, you should replace your mountain bike tires every 6 to 12 months, depending on how much you ride and the terrain you’re tackling.

What’s the best way to prevent getting flats on a mountain bike?

There are a few things you can do to reduce the risk of getting flats on your mountain bike. First, make sure your tires are properly inflated to the recommended PSI range. You should also consider using tire sealant, which can help seal small punctures from the inside. Finally, be mindful of the terrain and try to avoid sharp rocks or thorns that could puncture your tires.

Can I patch a tube instead of replacing it?

Yes, you can often patch a tube instead of replacing it, especially if the puncture is small. Use a patch kit and follow the instructions carefully to apply the patch. However, if the tube is significantly damaged or the puncture is large, it’s generally better to replace the tube entirely.

How do I properly store my spare inner tubes?

To ensure your spare inner tubes stay in good condition, store them in a cool, dry place away from direct sunlight. You can also lightly inflate them to help maintain their shape. When packing for a ride, be sure to protect the tubes from any sharp objects that could puncture them.

What’s the best way to dispose of a worn-out tire?

When it’s time to replace your mountain bike tire, don’t just toss it in the trash. Many bike shops and tire retailers will accept old tires for proper recycling or disposal. You can also check with your local waste management authority to see if they have a tire recycling program in your area.
