How to Mount and Balance TBR Tires?



Mounting and balancing TBR (Truck and Bus Radial) tires may seem like a daunting task, but with the right techniques and equipment, it can be easily accomplished. Properly mounting and balancing tires ensures optimal performance, longevity, and safety on the road. In this article, we will guide you through the step-by-step process of mounting and balancing TBR tires, from preparation to final adjustments. So, let's dive in and learn how to mount and balance TBR tires like a pro!

Preparing for the Task:

Before you begin the mounting and balancing process, it is crucial to gather the necessary tools and equipment. These include:

1. Tire Mounting Machine:

Ensure that you have a reliable tire mounting machine that can handle TBR tires. This machine allows you to secure and inflate the tire onto the rim effortlessly.

2. Balancer:

Use a high-quality tire balancer to achieve optimal balance. A balancer helps distribute weight evenly across the tire, reducing vibrations and enhancing overall performance.

3. Valve Stems:

Make sure you have new valve stems handy. Valve stems deteriorate over time, and replacing them during tire installation prevents air leaks.

4. Lubricant:

A water-based lubricant is imperative for smooth tire mounting. It minimizes friction between the tire bead and rim, making the process easier.

5. Wheel Weights:

Have a range of wheel weights available. These weights are essential to counterbalance any imbalance found during the balancing process.

Mounting TBR Tires:

Mounting TBR tires requires precision and care to avoid damaging the tire or rim. Follow these steps carefully:

1. Clean the Rim:

Prior to mounting, clean the rim thoroughly using a mild detergent and water. Remove any debris, rust, or old valve stems. Inspect the rim for any signs of damage or excessive wear.

2. Inflate the Tire:

Before mounting, ensure the tire is properly inflated to the manufacturer's recommended pressure. Check for any visible damage or irregularities on the tire.

3. Position the Tire on the Machine:

Place the tire onto the mounting machine, ensuring the sidewall aligns with the bead breaker. Use the tire machine's built-in bead breaker to loosen one side of the tire bead from the rim.

4. Apply Lubricant:

Apply a generous amount of lubricant to the tire bead and rim flange. This lubrication eases the mounting process and prevents damage to the tire or rim.

5. Secure the Tire:

With the first side of the tire bead loosened, adjust the mounting machine's arm to secure the tire firmly. Ensure the opposite side of the tire bead is positioned within the rim's drop center.

6. Rotate and Inflate:

Rotate the tire while guiding the bead onto the rim. This step requires patience and finesse. Gradually inflate the tire, periodically checking if the bead is seating properly. Continue inflating until the tire is seated evenly on the rim.

7. Repeat for the Other Side:

Once the first side of the tire is mounted, repeat the process for the other side of the tire. Remember to lubricate the tire bead and rim flange before securing the tire onto the rim completely.

8. Verify Bead Seating:

After mounting both sides, inspect the tire to ensure the beads are seated evenly on the rim. Tap the tire lightly with a rubber mallet to help the beads settle if necessary.

Balancing TBR Tires:

Balancing TBR tires is vital for a smooth ride and extended tire life. Here's how to balance the tires effectively:

1. Secure the Wheel:

Place the mounted tire and rim onto the balancer spindle, ensuring it is securely fastened. The wheel should spin freely without any interference.

2. Measure Wheel Imbalance:

Activate the balancer and allow it to analyze the wheel's imbalance. The balancer will identify the precise location and amount of weight required for proper balance.

3. Attach Wheel Weights:

Based on the balancer's readings, attach the appropriate wheel weights to the designated spots on the rim. Wheel weights are available in various sizes and shapes to match specific balancing requirements.

4. Fine-Tune the Balance:

Recheck the balance after adding weights. If necessary, make minor adjustments by removing, adding, or repositioning weights until the wheel is perfectly balanced.

5. Verify Balance:

Once the wheel is balanced, rotate it manually and observe if it spins smoothly. If there are no noticeable vibrations, the tire is successfully balanced.


Mounting and balancing TBR tires is an essential maintenance task that ensures optimal performance and safety on the road. By following the step-by-step process outlined in this article, you can confidently mount and balance your TBR tires like a professional. Remember to prepare the necessary tools, take your time during the process, and verify the balance for a smooth and comfortable driving experience. Properly mounted and balanced TBR tires will not only enhance vehicle performance but also contribute to a longer tire lifespan. So, equip yourself with the knowledge and skills to tackle this task with ease and keep your TBR tires rolling smoothly on the road.
