I’ve ran after-market 20x9 and 20x10 offset on my ‘11 X5d for 7 years on Bridgestone Runflats.
They were the Beyern mesh black matte fire forged wheels which did well till a pot hole cracked a rim recently. (Discount Tire)

So I switched back to my silver BMW factory rims.
I have an extra set of Snow RF’s which I’ll probably sell this year (mounted back the repaired Bayern rim set).

I’m debating keeping the X5d but will most likely sell it this Summer/Fall.
Only 40k miles and I have the extended warranty till May 2021.
