2021 Audi Lineup Normal Load Tire Pressure TSB

This manufacturer communication, identified as NHTSA ID 10180476, provides a detailed tire pressure table for a wide range of 2021 Audi vehicles. The document, titled "MY 2021 Audi Normal Load Condition (up to three people) Tire Pressure Table," serves as a technical service bulletin (TSB) to guide owners and technicians on maintaining optimal tire pressure for various models and tire specifications.

Maintaining the correct Audi e-tron tire pressure and for other Audi models is crucial for vehicle safety, performance, and tire longevity. This TSB specifically outlines pressures for normal load conditions, typically defined as up to three occupants.

Symptoms

This service bulletin does not address a specific vehicle fault or symptom. Instead, it provides essential information for vehicle maintenance. However, incorrect tire pressure can lead to several undesirable conditions:

• Premature or uneven tire wear: Tires can wear out faster and irregularly, requiring earlier replacement.
• Reduced fuel efficiency: Underinflated tires increase rolling resistance, leading to higher fuel consumption.
• Compromised handling and braking: The vehicle's stability, steering response, and stopping distance can be negatively affected, especially in emergency situations.
• Increased risk of tire failure: Severely underinflated tires can overheat and potentially lead to a blowout.

Fault Codes / DTCs

This manufacturer communication, NHTSA ID 10180476, is an informational document and does not list any diagnostic trouble codes (DTCs) or fault codes. It focuses solely on providing recommended tire pressure specifications.

What the Service Bulletin Says

The TSB, titled "MY 2021 Audi Normal Load Condition (up to three people) Tire Pressure Table," is a comprehensive guide to tire pressures for 2021 Audi vehicles. It details recommended front and rear tire pressures in PSI for numerous models, engine variants, and specific tire sizes (e.g., 225/50 R17, 245/40 R18, 255/35 R19, 265/30 R20, 275/35 R21, 285/30 ZR22, 295/40 ZR22, 295/35 ZR23). The table also differentiates between High Performance and All Season tires.

Important footnotes in the document clarify the normal load condition, specifying it as two people in the front and one in the rear for most models. For RS 5, RS 7, RS Q8, and TT RS models, the tire pressure recommendations may vary based on the vehicle's maximum permitted speed (e.g., values for up to 155 mph vs. up to 174 mph or 190 mph). Additionally, some A5/S5/RS 5 Sportback and A8L/S8L models have specific notes regarding four or five seating positions.

What to Do

To ensure optimal safety and performance for your 2021 Audi, it is essential to maintain the correct tire pressure. Locate your specific Audi model, engine size, and tire specifications in the detailed table provided by this TSB (NHTSA ID 10180476). For instance, if you own a 2021 Audi e-tron, find the exact tire size and type to determine the recommended front and rear PSI.

Regularly check your tire pressures, ideally once a month and before long trips, using a reliable tire pressure gauge. Always check pressures when the tires are cold. While this TSB provides comprehensive data, also consult your vehicle's door jamb sticker or owner's manual for additional information specific to your vehicle's configuration. Maintaining the correct Audi e-tron tire pressure (or for any other Audi model) helps prevent issues like premature tire wear and ensures your vehicle handles as designed.
