I've often wondered what the rolling resistance of the skinny antique car tires were. The wooden/steel banded horse-drawn wagon wheels have a very low rolling resistance, which they have to be, considering their limited output equine power source. The wheel/tire technology of the early cars was derived from the earlier horse-drawn wheel/tire technology and so would be expected to also have low rolling resistance to make the most of the limited power output of the early automotive engines. A Ford Model A weighs about 2200 lbs and runs on 3" wide tires mounted on a 19" wheel. These wheels and tires are still in productuon. It would be pricy, but it would be interesting to see what kind of mileage and handling/braking a set of these would produce if mounted on a modern car.
