I race electric race cars, 3 weeks ago I drove the NASA “25 Hours of Thunderhill” and I wish tire manufacturers made tires optimized for EV race cars, a 10% reduction in rolling resistance could easily have allowed us to go one more lap between battery swaps.
Great video, excellent summary of the design tradeoff challenges! In an EV race car wind noise predominates, my car is an open cockpit, so a small change in windscreen angle and and different helmet made a big difference, and then I could really hear the tires, which is great for the driver to be able to hear what the tires are “saying” at the limits of grip.
Oh, also, you are right about summer tires vs all-season, make the switch to summer tires when the weather allows, you won’t regret it.
