I've worked with people that worked on bmw OE programs and they go out of their way to push for extreme performance out of tire manufacturers. The i3 tire was actually very revolutionary for the industry(skinny/tall, meaning high sidewall and thin tread width) which had amazing RR.
Trust me if they wanted close enough they would accept bids from 3rd tier tire manufacturers like Toyo, Kumho, Yoko, and Falken, because those guys would literally give their OE tires away for free just to market on the BMW brand. Goodyear(Dunlop in EMEA) spent metric shitton on every BMW OE program. Michelin would lose every single RFP if they submitted tires for different cars.
