Knowing how to change the back tire on a mountain bike is a fundamental skill that every rider should have, as this can get you back on the trail quickly while avoiding unnecessary expenses at the bike shop.
In this step-by-step guide, we’ll walk you through the process of changing the back tire on your mountain bike. We’ll cover essential tools and materials that you’ll need, as well as some useful tips to make the process smoother and faster. So, whether you’re planning a day on the trails or just looking to upgrade your mountain bike maintenance skills, let’s dive into the world of back tire replacement.
Tools Required for Changing a Back Tire on a Mountain Bike
Before getting started on how to change the back tire on a mountain bike, it’s necessary to gather all the essential tools required for the job. The tools you’ll need include a tire lever, a bike stand or prop, a spare inner tube, a pump or CO2 inflator, and a multi-tool kit. Most importantly, ensure that you have the correct size and type of tire and inner tube before attempting to change the tire.
A tire lever is used to remove the tire from the rim. A bike stand or prop holds the bike in place during the process and ensures that it stays upright. The spare inner tube is a crucial backup in case the damaged tube cannot be repaired. A pump or CO2 inflator is used to inflate the tire once the new inner tube has been installed, and a multi-tool kit includes a range of tools such as Allen keys, screwdrivers, and wrenches, which are essential for loosening and tightening bolts during the process.

How to Remove the Back Wheel of a Mountain Bike
Removing the back wheel of a mountain bike is an essential step when changing a tire. Here’s how you can do it yourself.
First, shift the chain so that it is on the smallest cog of the rear cassette. Then, using a wrench, release the brake on the bike. Next, loosen the nuts or quick-release lever that holds the axle in place. Once the nuts or lever are loosened, pull the wheel out of the dropouts on the rear fork. Be sure to keep track of any spacers or washers that may be on either side of the wheel. Once the wheel is removed, you can proceed to change the tire or repair the inner tube. To reinstall the wheel, simply reverse the steps. Place the wheel back into the dropouts, making sure it is centered and aligned properly. Tighten the nuts or lever to secure the axle in place, and reattach any brake cables or quick-release levers that you removed earlier. By following these steps, you can feel confident in your ability to remove and reinstall the back wheel of your mountain bike.
Steps to Remove the Old Tire from the Rim
Removing the old tire from the rim is an essential step in changing the back tire of a mountain bike. This process can be challenging for beginners, but with proper guidance, it can be done quickly and efficiently. Firstly, undo the quick release skewer and remove the wheel from the frame.
Next, using a tire lever or a flat object like a screwdriver, insert the tool between the tire and the rim bead. Pull the lever towards you to lift the tire bead over the rim. Repeat this step on the opposite side of the tire to completely loosen the tire from the rim. Once the tire is loose, you can now remove it from the rim by pulling it off. Be mindful of the inner tube as it may still be attached to the tire. Gently remove the tube and the tire from the rim and set them aside for later examination.

Procedure for Mounting the New Tire onto the Rim
Mounting a new tire onto the rim can be tricky, but by following these simple steps, you can do it with ease. First, take your new tire and examine its direction of rotation. Look for the arrow that indicates the direction of rotation and make sure it is pointing in the correct direction. Then, place one side of the tire onto the rim, starting from the valve hole.
Once you have one side of the tire in place, use your hands to push the other side of the tire onto the rim, starting at the opposite end of the valve hole. Make sure the tire is seated evenly around the rim, and double-check that the direction of rotation is correct. Finally, use your thumbs to push the tire bead into the center of the rim to ensure both sides are securely in place. Congratulations! You have just successfully mounted a new tire on your mountain bike.
Tips for Inflating the New Tire to the Appropriate Pressure
Proper inflation of the new tire is crucial to ensuring a smooth and safe ride on your mountain bike. Before inflating the tire, check the recommended tire pressure specified by the manufacturer. This information is normally located on the sidewall of the tire. Use a reliable tire gauge to measure accurately the tire pressure. Most mountain bikes require a pressure range of between 30 to 50 psi. However, the pressure may differ depending on the type of terrain you will be riding on. For example, bumpy terrains will require pressure on the lower end of the spectrum, while smooth roads will require pressure on the higher end.
When inflating the tire, ensure that the valve cap is removed and the valve stem is in the upright position. Use a pump that can inflate a tire with controlled pressure. This helps to keep the tire from over-inflation which can lead to a burst. Also, take care to avoid pinching the inner tube with the tire bead when fitting the tire onto the rim. Finally, test the tire pressure with a gauge and make adjustments if necessary. By following these tips, you can ensure that your new mountain bike tire is inflated to the appropriate pressure for a safer and smoother ride.
Re-Attach the Back Wheel to the Mountain Bike
Now that you have removed the back wheel from your mountain bike and replaced the tire, it is time to reattach the wheel. But, before you get started, make sure that the tire is properly set onto the rim. Check that the valve stem is straight by using your fingers to push in any bulges that appear close to the valve stem. Then, inflate the tire to the recommended pressure level as stated on the tire’s sidewall.
To reattach the wheel, maneuver the chain back onto the gears of the cassette and then push the wheel into the dropouts. While holding the wheel in place, re-insert the axle through the hub. Make sure that the wheel is firmly in place before you tighten the quick-release skewer. After you have tightened the skewer, spin the wheel to check that it is centered. If the wheel is off-center, loosen the skewer and wiggle the wheel until it is centered. Finally, use a torque wrench to tighten the skewer to the manufacturer’s recommended torque level. Your back tire is now successfully reattached and ready for your next mountain biking adventure!

Methods to Check the Tightness and Alignment of the Back Tire and Wheel.
After successfully installing the back tire on your mountain bike, it is essential to check its tightness and alignment. The first method is to put the bike on a stand and give the back tire a good spin. While the wheel is rotating, observe whether it wobbles or moves from side to side. If you notice any wobbling or movement, it could mean that the wheel is not aligned correctly. To fix this, loosen the bolts holding the wheel in place and adjust it until it spins without wobbling.
The second method is to check the tightness of the bolts holding the wheel in place. It is crucial not to overtighten the bolts as this can damage the wheel or the frame. However, if the bolts are too loose, the wheel can shift, which can be dangerous while cycling. Check the bolts for tightness by using a torque wrench or tightening them by hand to the manufacturer’s recommended torque. Always double-check the alignment and tightness of the back tire before taking your mountain bike on the trails to ensure a safe and smooth ride.
Verdict
Changing the back tire on your mountain bike can seem like a daunting task, but with the right tools and knowledge, it can be done quickly and efficiently. The first step is to gather all the necessary tools and ensure that your bike is secure before beginning the process. Once you have removed the wheel, inspect the tire and replace it if necessary. You can then easily change the tube and reattach the wheel to your bike. Following these steps will get you back on the trail in no time.
