Tesla: Foam in the Tires, Between Comfort and Concerns

For the sake of acoustic comfort, Tesla fills the tires of first assembly with foam, sparking both praise and concerns.

The issue appears to be significant among Tesla owners, who are surprised by varying acoustic performance depending on the tires installed on their vehicle from the factory. When the tires are later replaced with mileage, they do not regain the same quietness that initially appealed to them at purchase, etc.

But the real problem lies elsewhere: the failure of these first tires when they include the famous “Tesla foam”. Here is a testimony posted on the first Facebook forum for Tesla Model Y owners in France.

The Advantages: Increased Comfort and Performance

The insertion of foam inside the Tesla tires aims to offer several benefits. Firstly, the foam significantly reduces rolling noise, providing a quieter and more pleasant driving experience. By absorbing vibrations and shocks from road irregularities, it also enhances driving comfort. Additionally, the foam helps stabilize the tires by maintaining a more constant internal pressure despite temperature variations, which can extend their lifespan.

The Disadvantages: Cost and Complexity

However, this technology is not without drawbacks. Adding foam increases manufacturing costs of tires, resulting in a higher price for consumers. Repairing these tires is also more complex and costly, requiring specialized equipment and training in repair centers. Although the impact on energy efficiency is minimal, the additional weight of the foam could slightly affect energy consumption and the range of electric vehicles.

Reliability Issues: Concerned Owners

A major problem reported by several Tesla owners concerns the reliability of the foam. Indeed, some have noticed that the foam detaches inside the tires, causing noticeable imbalances. These imbalances lead to vibrations and driving discomfort, requiring frequent rebalancing. More worryingly, these imbalances can affect handling and vehicle stability, increasing the risk of accidents.

Increased Maintenance and Limited Availability

The deterioration of the foam leads to increased maintenance costs and closer monitoring of tire condition. Furthermore, not all types of tires are available with this technology, limiting options for consumers when replacing their tires.

Conclusion: A Choice to Be Made Carefully

The use of foam in Tesla tires offers undeniable advantages in terms of comfort and noise reduction. However, reliability issues and additional costs must be carefully considered. Tesla and tire manufacturers will need to continue improving this technology to ensure its durability and performance. Meanwhile, drivers should be informed of the pros and cons to make educated decisions about their vehicle.

For those experiencing issues, it is recommended to consult a tire specialist or a Tesla service center to find suitable solutions.
