GoPro Inside a Car Tire (With Balance Beads)

Summary

In this video, the creator tests the effectiveness of balance beads inside a car tire by mounting a GoPro to capture the real-time impact of these beads on tire balance. Despite some early difficulties in adding the beads, the tire is mounted and tested on a balancing machine, showing surprising results with the beads keeping the tire relatively balanced. The creator then takes the tire for a test drive, navigating bumpy roads and reaching higher speeds to observe the beads' performance under real-world conditions. The experiment concludes with a revelation that the balance beads actually work, leaving the creator intrigued and seeking further understanding of how they function.

Takeaways

• 😀 The project involves mounting a GoPro inside a car tire to observe the effect of balance beads on tire balancing.
• 😀 Balance beads are designed to automatically balance a tire by adjusting to weight imbalances caused by tire wear.
• 😀 The tire being used is in great condition, but the test aims to see how balance beads perform if some rubber pieces break off during driving.
• 😀 The balance beads are primarily used in truck tires but are now being applied to various types of tires, including motorcycles and cars.
• 😀 The process of adding balance beads involves either pouring them directly into the tire or using a bottle to inject them through the valve stem.
• 😀 The initial attempt to inject the balance beads through the bottle method fails, leading to a direct method of dumping them into the tire.
• 😀 After mounting the tire, a balance machine is used to test the tire’s balance before mounting it back on the truck.
• 😀 The balance beads show significant effectiveness, reducing the imbalance to just 2 oz, even with the GoPro inside the tire.
• 😀 After a second test, the imbalance is further reduced to 1.5 oz, proving that the balance beads are dynamically adjusting to changes in tire position.
• 😀 The balance beads maintain their effectiveness even during driving, as demonstrated during a test drive on a bumpy street where the beads kept the tire balanced.
• 😀 The GoPro inside the tire survived the centrifugal forces, and the balance beads performed as expected, with the tire staying balanced despite the tire's dynamic changes.
• 😀 The creator is still puzzled by how the balance beads work but acknowledges that they appear to be effective at maintaining tire balance.

Q & A

What is the main goal of the video project?

The main goal of the project is to test the effectiveness of balance beads inside a tire and see how they work to maintain balance, especially when driving at different speeds and on uneven roads.

How does the speaker plan to test the balance beads?

The speaker plans to test the balance beads by mounting a GoPro inside a tire with the beads and then checking the tire's balance both using a balance machine and by driving the vehicle to observe how the beads affect the tire's performance.

What challenges does the speaker face when trying to insert the balance beads?

The speaker initially struggles to insert the balance beads into the tire using the provided bottle method, as it doesn't flow smoothly. The speaker eventually gives up on this method and opts to manually dump the beads into the tire after removing it from the rim.

What is the speaker's expectation regarding the balance beads' performance?

The speaker does not expect the balance beads to work perfectly but hopes that they will at least improve the tire's balance and compensate for any loss of rubber or tire imbalance.

How does the balance machine show the tire's balance after the beads are inserted?

After mounting the tire on the balance machine, the speaker observes that the tire is only slightly off balance (about 2 oz). This suggests that the balance beads are working, even with the GoPro inside the tire.

What result does the speaker get when testing the tire balance a second time?

When the tire is spun up a second time, the balance improves further to 1.5 oz off balance, confirming that the balance beads are dynamically adjusting to changes in the tire's movement and weight distribution.

What happens when the speaker takes the vehicle for a drive?

During the test drive, despite encountering bumps, the balance beads maintain their position relative to the tire, suggesting that they are effectively balancing the tire in real-time. However, the GoPro is at risk of being detached due to centrifugal force.

Does the GoPro survive the test drive?

Yes, to the speaker's surprise, the GoPro survives the drive, and the balance beads work as expected, despite the high-speed bumps.

What is the speaker's reaction to the performance of the balance beads?

The speaker is surprised and impressed by the performance of the balance beads, as they work better than expected, even though the speaker initially doubted their effectiveness.

How does the speaker feel about the scientific explanation behind how the balance beads work?

The speaker is still unsure about the exact scientific mechanism of the balance beads, especially how they can counteract an off-balance tire, and asks viewers to share their insights on how the beads work.
