Performance tires and summer tires are synonymous. I assume you have the VIN? Even though the car is new the odds are pretty high it will show up on either
www.bimmer.work or
www.mdecoder.com . If it shows option 840 High Speed Synchronization then it has staggered summer/performance tires. That’s what I have on my rwd 340i here in Chicago and I have a dedicated set of winter wheels and tires that I swap out twice a year. My winter tires with rwd do better than other folks xDrive with all seasons.
