Removing the Old Mountain Bike Tire
Removing the old mountain bike tire is an important step in changing a tire. Here are the steps to remove the old tire:
- Deflate the tire: Loosen the cap on the air valve and release the air using the correct procedure for your air valve type. This will make it easier to remove.
- Remove the wheel: If you’re removing the rear tire, you may need to lift the bicycle chain out of the way. Unscrew the nut on the other side of the axle with a wrench.
- Loosen the tire from the rim: Insert a tire lever under the outer edge of the tire, then lift it up and over the rim of the wheel. Work a second tire lever clockwise around the circumference of the tire. Insert the second lever near the first one, then press up on the tire. Move the lever clockwise around the tire, pushing up on the tire as you go. Keep going until the entire side is loosened from the frame. You may be able to remove your tire with a spoon or screwdriver, but they can damage your tire.
- Remove the tire from the wheel: After the tire is loosened from the rim, use your fingers to pull the tire off the wheel. You may need to work it back and forth to get it completely off.
- Remove the tube from the tire: Pull the tube out of the tire. The valve stem connects to the tube, not the tire, so removing it first will let you pull the entire tube out.
By following these steps, you can successfully remove the old tire from your mountain bike.
Inspecting the Inner Tube and Rim Strip
Inspecting the inner tube and rim strip is an important part of changing a mountain bike tire. It helps in identifying any potential issues that may cause future flats or damage to the tire. Here’s how to inspect the inner tube and rim strip:
- Remove the wheel: Before you can inspect the inner tube and rim strip, you must remove the wheel from the bike. This can be done by loosening the quick-release lever, unscrewing the nuts or bolts, or releasing the brake if it is a rim brake.
- Remove the tire and inner tube: To inspect the inner tube and rim strip, it is best to remove both completely. First, remove the tire by prying the bead off the rim with tire levers. Then, remove the inner tube by pulling it out of the tire.
- Inspect the inner tube: Always inspect the inner tube when servicing a flat tire. Look for any holes, punctures, or signs of damage. Inflate the inner tube slightly and listen for any hissing sounds, which indicate a puncture.
- Inspect the tire: Inspect the tire for any signs of damage such as cuts, holes, or tears. Look for any embedded objects that may have caused the puncture. Inspect the sidewalls for any cracks or bulges.
- Inspect the rim strip: The rim strip is a thin strip of material that covers the spoke holes in the rim. Inspect the rim strip for any tears or rips. Ensure that the rim strip is centered over the nipple.
- Inspect the rim: Inspect the rim for any damage or sharp edges that may puncture the inner tube. Look for any protruding spokes or sharp corners inside the rim cavity.
- Replace the rim strip: If the rim strip is damaged or worn, replace it with a new one. A worn or damaged rim strip can cause flats by exposing the inner tube to sharp edges in the base of the rim.
Inspecting the inner tube and rim strip is an essential part of maintaining a mountain bike tire. It helps in identifying potential issues that may cause future flats or damage to the tire. By following these steps, you can ensure that your bike is in good condition and ready for the next ride.

Checking Tire Pressure and Alignment
Checking tire pressure and alignment are important parts of changing a mountain bike tire. Here are some tips and information:
Checking Tire Pressure:
- The recommended PSI for a tire is usually stamped onto the sidewall of the tire.
- Tire pressure should be checked regularly before every ride is ideal.
- Most mountain bike tires are rated for 25-50 PSI.
- Tire pressure changes with temperature and elevation, and you may need to adjust the numbers depending on where and when you’re riding.
- You can use a pressure gauge to get an accurate reading of your tire pressure.
- Loads of riders check their pressure with the palm of their hand, using feel to determine how much air is inside. However, this method is less accurate than using a gauge.
- If your tire is not aligned correctly, it can cause uneven wear and tear on your tire.
- To check alignment, spin your tire and observe if there is any wobbling or wiggling.
- If you notice any misalignment, you can adjust the spokes on your wheel to fix the issue.
Overall, taking the time to properly check your tire pressure and alignment can help prolong the life of your tires and improve your riding experience.
