Tire Maintenance Tips for the Audi A4
Proper tire maintenance extends tire life and keeps your 2023 Audi A4 safe on the road. Follow these guidelines from NHTSA:
- Check tire pressure monthly — the Audi A4 requires 35/38 PSI (front/rear). Check when tires are cold, before driving.
- Rotate tires every 5,000–7,500 miles — this ensures even wear across all four tires, especially important for vehicles with staggered setups.
- Inspect tread depth regularly — the legal minimum is 2/32", but most experts recommend replacing tires at 4/32" for adequate wet traction.
- Check the DOT date code — tires older than 6 years should be inspected by a professional, regardless of tread depth. The 4-digit DOT code on the sidewall shows the week and year of manufacture.
Choosing Alternative Tires
When replacing tires on your 2023 Audi A4, stay within 3% of the factory tire's overall diameter to avoid affecting your speedometer accuracy, ABS calibration, and traction control. The factory bolt pattern (5x112) and offset (35-45) must also match.
Always verify any alternative size with a qualified tire professional before purchase. For more information on tire safety, see the NHTSA Tire Ratings Search.
