AUDI TTS Wheel Lug Patterns, Offset ET & Center Bore Reference

The AUDI TTS requires specific wheel lug patterns defined by lug count and pitch circle diameter (PCD) to ensure proper mounting. When selecting wheels, understanding the AUDI TTS bolt pattern is crucial for compatibility and safety. This includes verifying the lug count × PCD, usually 5x112 mm for most AUDI TTS models, alongside the center bore dimension that centers the wheel on the hub.\n\nOffset ET values for the AUDI TTS vary by production year but typically range between ET25 and ET45. The offset affects wheel positioning relative to the suspension and fenders, directly impacting handling and clearance. Choosing the correct offset is key to maintaining factory performance and avoiding issues like rubbing.\n\nRim sizes compatible with AUDI TTS wheels generally span from 18 to 20 inches in diameter, balancing aesthetics and ride comfort. Combining the right rim size with accurate bolt pattern specs ensures optimal fitment for the vehicle. Reference tables sorted by year provide detailed AUDI TTS wheel lug patterns, offset ET, and center bore data for precise wheel selection.
