The Lucid Air Dream Edition travels up to 520 miles (837 km) on a charge, more than any electric vehicle on the market by a wide margin. If a buyer chooses the larger, 21-inch wheels, however, 39 (63 km) of those miles vanish — a 7.5% range penalty.

To be fair, the bigger shoes do look cool, and they’ll still take you nonstop from New York to Cleveland. But when it comes to wheels and tyres — where the rubber literally meets the road on electric vehicle range — there’s an escalating battle between physics and aesthetics.

But auto executives and engineers must layer in a dizzyingly complex series of compromises when outfitting a car in reality. For every bit of size and/or stickiness, the vehicle sacrifices mileage and efficiency. “Those are just cool wheels,” he explains. “We’re showing that when you get to EV, you can still have fun products.”

Ford likewise concedes that its Mustang Mach-E would go slightly farther if it chose tyres that didn’t corner as well, and its F-150 Lightning could stretch a few more miles on rubber less suited for off-road driving.
