2022-2026 Audi Collapsible Spare Wheel Inflation TSB

Owners of certain Audi models may notice that their collapsible spare wheel does not seem to inflate completely when using the compressor from the vehicle's tool kit. This can lead to concerns about the spare tire's readiness for use. Technical Service Bulletin (TSB) 2065160/3 from Audi clarifies this situation, explaining that the perceived underinflation is often a misunderstanding of the tire's design and the correct inflation procedure, rather than a fault with the component itself. This TSB is informational and does not indicate a defect requiring a repair.

Symptoms

Owners may observe that the temporary or collapsible spare wheel does not appear to inflate fully when using the compressor provided in the vehicle's breakdown set. The pressure specified on the collapsible spare wheel might not seem to be reached, leading to concerns about the tire's usability. This perceived issue, such as with the Audi e-tron spare wheel inflation, is the primary symptom addressed by this TSB.

Diagnosis / Trigger Conditions

The TSB explains that the collapsible spare wheel is designed to be used when the tire tread is aligned horizontally with the hub. Due to this design, the side wall of the collapsible spare wheel may not align symmetrically with the rim, which can give the impression that the tire is not fully inflated. The compressor is designed to reach a pressure of 3.5 bar (approximately 51 PSI) after running for a certain period, which is sufficient for temporary use and allows the vehicle to be driven.

This condition is not applicable to vehicles equipped with a 4.2 bar compressor from the factory.

Repair Procedure Summary

This Technical Service Bulletin is informational only, and no specific repair is required or applicable to any Audi warranty. The key to resolving the perceived Audi e-tron spare wheel inflation issue is to follow the correct procedure for fitting and inflating the spare wheel as outlined in the Owner's Manual. The TSB highlights the following steps:

1. Fit Before Inflation: The temporary spare wheel should be fitted onto the vehicle before it is inflated.
2. Inflate on Ground: After fitting, place the vehicle back on the ground, and then inflate the tire using the compressor.
3. Post-Inflation Appearance: The tire may appear more symmetrical after a short drive.

It's crucial to remember that the collapsible spare wheel is intended only for temporary use to enable driving the vehicle again and is not designed for long journeys. Always ensure you do not exceed the permitted maximum speed for the spare tire and replace it with the original tire as soon as possible.

Owner Action

If you experience concerns about your Audi e-tron spare wheel inflation, it's important to consult your vehicle's Owner's Manual for detailed instructions on how to properly fit and inflate the temporary spare wheel. Understand that the visual appearance of the inflated collapsible spare wheel might differ from a standard tire, but the 3.5 bar pressure provided by the compressor is adequate for temporary use. This TSB does not require a visit to the dealer for a repair, as it is an informational bulletin clarifying the design and intended use of the collapsible spare wheel.
