Understanding Audi S4 Wheel Fitment for 2015: Clearing Up Common Misconceptions

When it comes to fitting wheels on your 2015 Audi S4, there are a lot of misconceptions floating around. One common belief is that all wheels with the same bolt pattern will fit any vehicle. This can lead to confusion and potentially costly mistakes.

Why It Seems True

It makes sense at first glance: if two vehicles have the same bolt pattern, surely their wheels are interchangeable. However, factors like offset, backspacing, and center bore play crucial roles in determining whether a wheel will fit correctly. So, while the bolt pattern is a key detail, it’s not the whole story.
