Hey everyone, excuse my ignorance… I just need some help. I found out recently after getting a wheel balance that the reason my car shakes isn’t bc of the wheels being unbalanced but it’s because some of my wheels are bent up.

So I bought a new set of wheels from an online refurbished wheel seller. I ordered the exact set of wheels I have on the car now. After placing my order, a rep from the company contacted me and asked if I wanted a “staggered set of wheels because that is how they come from BMW”

I’m reading different things and getting different answers and not sure what to do. I heard it can ruin your differential by having 2 different size wheels? Is that true?

I have an AWD 540 and would be putting 2 19x8 on the front and 2 19x9 on the rear
