Pay special attention to the bead area of the tire, as well as the wheel’s mounting surface, to ensure a clean and secure fit.

After cleaning, it’s essential to lubricate the tire beads. This step helps the tire slide onto the wheel more easily and creates a better seal. Use a tire lubricant or a vegetable-based lubricant specifically designed for this purpose. Apply a thin, even layer of lubricant to both the tire beads and the wheel’s mounting surface, taking care not to over-lubricate, which can cause the tire to slip or spin on the wheel.

With the tire and wheel properly prepared, you’re now ready to proceed with the mounting process.

Demounting the Old Tire

Removing the old tire from the wheel is a crucial step in the tire mounting and demounting process. Here’s a step-by-step guide to demounting the old tire:

1. Deflate the Tire: Before attempting to remove the tire, you must completely deflate it. Use a tire valve tool or a valve core remover to let out all the air from the tire.
2. Break the Bead: The bead is the edge of the tire that fits tightly against the wheel rim. To remove the tire, you need to break the bead free from the rim. This can be done using a tire bead breaker tool or a specialized bead breaker machine. Apply the bead breaker tool to the tire’s sidewall and lever it against the rim to break the bead.
3. Lubricate the Tire: Apply a tire lubricant or a soap and water solution to the tire beads and the rim. This will help the tire slide off the rim more easily.
4. Mount the Tire on the Demounting Tool: Place the tire on a tire demounting tool or a tire machine. This tool is designed to hold the tire securely while you pry it off the rim.
5. Use the Tire Lever: Start at the point where the bead is already broken and insert the curved end of a tire lever between the tire bead and the rim. Carefully work the lever around the circumference of the tire, prying the bead over the rim’s edge.
6. Remove the Tire from the Rim: Once the bead is completely separated from the rim, you can lift the tire off the wheel. Be careful not to damage the rim or the tire during this process.
7. Inspect the Tire and Rim: After removing the tire, inspect both the tire and the rim for any signs of damage, wear, or debris. Clean the rim thoroughly before mounting the new tire.

It’s important to follow proper safety precautions and handle the tire and tools with care to avoid injury or damage. If you encounter any difficulties or are unsure about the process, it’s best to seek professional assistance.

Mounting the New Tire

Mounting a new tire onto a wheel is a crucial step that requires attention to detail and proper technique. Follow these steps to ensure a successful tire mounting process:
