Changing a tire can be a daunting task, especially if you’re not mechanically inclined. However, with the right tools and a little know-how, you can easily change a tire on a rim by hand. This step-by-step guide will show you how to do it safely and efficiently.
Before you start, gather the necessary tools and materials: a tire iron, a bead breaker (optional), a rag, and a lubricant. You may also want to wear gloves to protect your hands. Once you have everything you need, follow these steps to put a tire on a rim by hand:
First, lay the tire flat on the ground and insert the tire iron into the space between the tire and the rim. Use the tire iron to pry the tire bead away from the rim. Once the bead is loose, use your hands to pull the tire off the rim. Be careful not to damage the tire bead or the rim. Next, inspect the rim for any damage or debris. Remove any debris or rust with a rag. If there is any damage to the rim, you may need to have it repaired before mounting the new tire. Apply a thin layer of lubricant to the bead of the new tire. This will help the tire to slide onto the rim more easily. Lift the tire onto the rim and start to push it into place, using the tire iron to help you. Once the tire is in place, use the tire iron to pry the bead back over the rim. Finally, inflate the tire to the recommended pressure and check for any leaks.
Gathering the Necessary Tools
Before embarking on the task of mounting a tire onto a rim by hand, it is crucial to gather all the necessary tools to ensure a smooth and efficient process. The following tools are essential for a successful tire mounting:
Tire irons: These specialized tools, typically made of metal, are designed to leverage the tire bead over the rim. Using tire irons involves inserting them between the tire bead and rim and applying force to pry the bead over the rim edge.
Rim protectors: These protective plastic or rubber coverings fit over the rim edge to prevent scratching or damage during the tire mounting process. They serve as a barrier between the metal tire irons and the rim, shielding it from any potential abrasions or nicks.
Valve stem tool: This specialized tool is used to remove and install the valve stem inside the tire, allowing for inflation and deflation. It is crucial to have a dedicated valve stem tool to ensure the proper handling and installation of the valve stem without damaging it.
Lubricant: A tire mounting lubricant, typically a water-based solution or soapy water, is used to reduce friction between the tire bead and rim. This lubrication eases the mounting process and prevents damage to the tire or rim during the bead seating process.
Air compressor and tire gauge: Once the tire is mounted, an air compressor and tire gauge are required to inflate the tire to the proper air pressure specifications. The tire gauge provides an accurate measurement of the tire pressure, ensuring it is within the recommended range.
Additionally, it is recommended to wear safety gloves during the tire mounting process to protect hands from potential cuts or abrasions.

| Tire irons | Metal tools for prying tire bead over the rim |
| Rim protectors | Plastic or rubber coverings to protect rim edge |
| Valve stem tool | Tool for removing and installing valve stem |
| Lubricant | Water-based solution or soapy water to reduce friction |
| Air compressor and tire gauge | For inflating tire and measuring tire pressure |
| Safety gloves | For hand protection during mounting process |
Preparing the Tire and Rim
Before starting, ensure you have all the necessary tools, including tire irons, a bead seater, and a tire gauge. Gathering these items beforehand will save time and prevent interruptions during the process.
Cleaning the Rim and Tire
Begin by thoroughly cleaning the rim and tire surfaces where they will come into contact. Use a wire brush or a stiff brush with detergent and water to remove any dirt, grime, or debris. This step is crucial to ensure a proper seal and prevent air leaks.
Lubricating the Rim
Apply a thin layer of tire lubricant or soapy water to the bead of the rim where the tire will sit. This lubrication will reduce friction and make it easier to mount the tire. It is recommended to use a specific tire mounting lubricant for optimal results.
Inspecting the Rim
Before mounting the tire, carefully inspect the rim for any damage, such as dents, bends, or cracks. Ensure the valve stem is straight and properly aligned.
| Tools |

| Tire irons |
| Bead seater |
| Tire gauge |
| Wire brush or stiff brush |
| Detergent |
| Tire mounting lubricant or soapy water |
Lubricating the Bead
The next step is to apply a lubricant to the bead of the tire. This will help it to slide into place more easily and reduce the risk of pinching the tube. You can use a commercial tire lubricant, or you can make your own by mixing dish soap with water in a spray bottle. Spray the lubricant liberally onto the bead, making sure to pay special attention to the sidewalls.
Once you have lubricated the bead, it’s time to mount the tire onto the rim. To do this, start by positioning the tire so that the bead is aligned with the rim. Then, use your hands to push the tire onto the rim, working your way around the circumference of the wheel. As you push the tire onto the rim, make sure to keep the bead lubricated so that it doesn’t get pinched. Once the tire is fully seated on the rim, you can use a tire lever to finish mounting the tire. Use the tire lever just to help push the non-seated sidewall to the rim by using the tire lever between the tire and rim. Do not use the tire lever to pry the tire on to the rim, this could cause damage to the tire or tube.

| Commercial tire lubricant |
| Dish soap mixed with water |
Inserting the First Bead
Inserting the first bead can be the most challenging step in mounting a tire by hand. Here’s how to do it step by step:
1. Position the Tire:
Place the tire on the rim, aligning the bead with the rim’s edge and leaving about 6 inches of the bead exposed.
2. Use a Tire Lever:
Insert a tire lever between the bead and the rim at a point opposite the exposed portion.
3. Pry the Bead:
Gently pry the bead up and over the rim, working around the circumference of the tire. Be careful not to pinch or puncture the tube.
4. Use Your Feet for Leverage:
Once the bead is mostly over the rim, use your feet for extra leverage. Step on the inside edge of the tire near the exposed bead, using your body weight to push the tire down onto the rim. Grip the tire with one hand and pull up on the bead with the other, while simultaneously pushing down with your foot.
Continue working around the circumference of the tire, alternating feet and prying the bead over the rim until the entire bead is fully seated.
| Step | Description |
|---|---|
| 1 | Position the tire so that about 6 inches of the first bead is exposed. |
| 2 | Insert a tire lever at a point opposite the exposed bead. |
| 3 | Pry the bead up and over the rim, starting at the insertion point and working around the circumference. |
| 4 | Use your feet for leverage to push the tire down onto the rim and pull the bead over. |
Working the Second Bead
Now that one bead is set, you can move on to the second one. This is where it gets a little more challenging, as the tire will be more difficult to stretch over the rim. But don’t worry, with a little patience and effort, you can do it.
Start by pushing the tire down onto the rim
Start by pushing the tire down onto the rim, as close to the first bead as possible. Use your hands or a pry bar to work the tire bead over the rim. You may need to use a lot of force, so be sure to use your body weight to your advantage.
Once the tire bead is over the rim
Once the tire bead is over the rim, you can start to work it around the rim. Use your hands or a pry bar to push the tire bead into the rim’s bead seat. You may need to use a lot of force, so be sure to use your body weight to your advantage.
Work your way around the rim
Continue working your way around the rim, pushing the tire bead into the rim’s bead seat. As you go, you may need to use a pry bar to help you get the tire bead over the rim’s humps. Once the tire bead is fully seated, you can use your hands to smooth it out and make sure it is properly seated.
Inflate the tire
Once the second bead is on, you can inflate the tire to the recommended pressure. This will help to set the beads and make sure that the tire is properly seated on the rim.
Setting the Bead
Once the tire is partially mounted on the rim, it’s time to set the bead. This involves pushing the tire’s bead over the edge of the rim.
Materials Needed:
- Tire levers (2 or 3)
- Soap or lubricant
- Towel or rag
Steps:
- Lubricate the bead and rim: Apply a generous amount of soap or lubricant to the bead of the tire and the rim surface where the bead will sit. This will help the bead slip into place more easily.
- Position the tire: Place the tire over the rim so that the bead is aligned with the edge of the rim.
- Insert a tire lever: Insert a tire lever between the bead of the tire and the rim. Position the lever about 10-15 cm (4-6 in) away from the valve stem.
- Pry up the bead: Use the tire lever to pry up the bead of the tire over the edge of the rim. This may require some force, but be careful not to pinch or damage the tire.
- Remove the tire lever: Once the bead is over the edge, remove the tire lever.
- Work around the rim: Continue this process around the entire circumference of the rim, inserting the tire lever a few centimeters at a time and prying up the bead. Keep the tire levers close together to maintain even pressure and avoid damaging the tire or rim.
Tips for Setting the Bead
- Use two tire levers: This will provide more leverage and make the process easier.
- Keep the levers parallel to the rim: This will help prevent the tire from slipping off the rim.
- Don’t overtighten: Be careful not to apply too much force with the tire levers, as this can damage the tire or rim.
- Use a towel or rag: If you’re struggling to set the bead, try using a towel or rag to protect your hands from the tire levers.
Inflating the Tire
Fine-tuning the Inflation
Once the tire is mostly seated on the rim, it’s time to fine-tune the inflation. Begin by checking the tire’s sidewall for the recommended inflation pressure, typically measured in pounds per square inch (psi). Using a tire pressure gauge, gradually inflate the tire by short bursts, monitoring the pressure carefully. If you overinflate the tire, it can cause a blowout or damage the rim. Equally, underinflation can lead to poor handling and premature tire wear.
Locking the Bead
As you inflate the tire, the bead will gradually lock onto the rim. This is an important step that ensures the tire remains securely in place at high speeds and under various driving conditions. To lock the bead, continue inflating the tire until you hear a series of loud “pops” or “bangs.” These noises indicate that the bead has fully seated on the rim. Once the bead is locked, check the tire pressure again and adjust as necessary to the recommended psi.
Final Checks and Precautions
After inflating the tire, it’s essential to perform a few final checks and precautions to ensure its safety and performance. Check that the tire is properly seated on the rim and that there are no visible bulges or irregularities. Tighten the valve core to prevent any leakages. Additionally, recheck the tire pressure after a few hours or a day of driving to ensure it hasn’t changed significantly.
| Recommended Inflation Pressure | PSI |
|---|---|
| Passenger Cars | 32-35 |
| SUVs | 35-40 |
| Light Trucks | 45-50 |
Checking for Leaks
Once the tire is fully seated on the rim, it is important to check for leaks. This can be done by spraying a mixture of soapy water around the bead of the tire. If there are any leaks, you will see bubbles forming. If you find any leaks, you can use a tire sealant to plug them.
Alternatively, you can check for leaks by submerging the tire in a tub of water. If there are any leaks, you will see air bubbles escaping from the tire.
Here are the steps you can follow to check for leaks using soapy water:
Materials you will need:
| # | Material |
|---|---|
| 1 | Soapy water |
| 2 | Spray bottle |
Steps:
- Spray the soapy water around the bead of the tire.
- Look for any bubbles forming.
- If you find any leaks, mark them with a piece of chalk.
- Use a tire sealant to plug the leaks.
- Re-inflate the tire to the recommended pressure.
Installing the Valve Stem
Before you can install the tire, you need to install the valve stem. The valve stem is a small metal tube that allows air to enter and exit the tire. It is important to make sure that the valve stem is installed correctly, or the tire will not hold air.
1. Thread the valve stem onto the rim.
Start the valve stem by hand and then tighten it using a valve stem tool. Do not overtighten the valve stem, or you could damage it.
2. Apply a few drops of valve stem sealant to the base of the valve stem.
This will help to seal the valve stem and prevent air leaks.
3. Install the valve stem cap.
The valve stem cap helps to protect the valve stem from dirt and debris.
| Valve Stem Height | Rim Hole Diameter |
|---|---|
| 30-50mm | 11.3mm |
| 55mm | 11.5mm |
| 60mm | 12.6mm |
| 65mm | 13.3mm |
| 70mm | 14.6mm |
If you are having trouble installing the valve stem, you may need to use a valve stem tool. A valve stem tool is a small tool that helps to guide the valve stem into the rim hole. You can find valve stem tools at most auto parts stores.
Balancing the Tire
Balancing the tire is crucial for ensuring a smooth and safe ride. Here are the steps to balance a tire by hand:
1. Mount the Tire on the Rim
Place the tire on the rim and align the valve stem with the valve hole. Use tire levers to pry the bead over the rim.
2. Seat the Bead
Inflate the tire to the recommended pressure. This will help seat the bead securely.
3. Remove the Tire Lever
Carefully remove the tire levers while holding the tire in place.
4. Spin the Tire
Rotate the tire slowly and check if there are any noticeable wobbles or imbalances.
5. Use a Balance Weight
If the tire is not balanced, add a balance weight to the heavy side.
6. Check Balance Again
Spin the tire again and check if the balance is improved.
7. Fine-Tune the Weight
If necessary, adjust the weight slightly until the tire spins smoothly and without any apparent imbalances.
8. Secure the Weight
Use a hammer or pliers to secure the balance weight firmly in place.
9. Final Check
Spin the tire one last time to ensure that it is balanced properly.
10. Detailed Guide to Using a Balance Weight
To use a balance weight effectively, follow these steps:
| Step | Description |
|---|---|
| 1 | Determine the heavy side of the tire. |
| 2 | Attach a small balance weight to the heavy side, approximately 1/4 of the way from the valve stem. |
| 3 | Spin the tire and check the balance. |
| 4 | If the imbalance persists, gradually increase the weight until the tire is balanced. |
| 5 | Use a weight gauge or ruler to measure the distance from the valve stem to the weight for future reference. |
