Lancia Dedra SW Wheel Lug Pattern, Offset & Rim Size Reference
The Lancia Dedra SW features specific wheel lug patterns critical for proper wheel fitment and safety. Its lug pattern is defined by lug count and pitch circle diameter (PCD), typically measured in millimeters. This page consolidates wheel mounting specifications such as bolt pattern, offset (ET), and center bore across all years of the Dedra SW.\n\nOffset (ET) values play an essential role in ensuring the wheels sit correctly within the wheel arches, affecting handling and suspension. The center bore size matches the hub diameter to secure the wheel properly and prevent vibrations. Rim sizes vary depending on the model year and trim but always conform to the designated lug pattern and offset.\n\nReference tables available here present year-by-year data for the Lancia Dedra SW, including precise lug count × PCD measurements, suitable offset ranges, and compatible rim diameters. This data supports accurate wheel replacements, upgrades, or retrofits while maintaining vehicle safety and performance.\n\nWhen selecting wheels for the Lancia Dedra SW, verifying compatibility with the documented bolt pattern, offset, and center bore is paramount to avoid fitment issues. This guide helps enthusiasts and professionals identify the correct wheel specifications with ease.
