I was changing my tires to summer ones today to find while loading them into my car. The dealer gave me a brand new one instead of my tire when they installed my winter ones back in a the fall!! I am attaching the photo side by side to see the difference, very slight though same exact tire, 2019 design vs 2021 design per tirerack

The dealer says no issues at all, wanted to check with the experts here in the forum to make sure.

New: Blackwall Alternate Design 2021
vs
Old: Style: Blackwall Design 2019

Do both have the BMW star?

hdahman · 05-12-2022, 07:15 AM

yes it does. the difference in pattern is at top edge in the picture.
probably those 2 pics I got from tirerack will show the difference much better

Is there a way to contact BMW to verify such technical question without going to dealer?

I have tried in the past to ask bmw Customer service but they always tell me to go to dealer!

I have those on my X6MC and they are slippery, the EOM was more gripper, with new design pirelli I can drift around the corner given time, original tire wod grip instead of slid.

The issue is I have 3 old tires with old tread pattern and one tire new with what's called black wall alternate design. Dealer said it's fine, I am having hard time to believe it. If as you said the new is slippery, that one tire could cause damage?

One is tagged “performance” and the other “luxury” if you look closely on tirerack
