  • I can speak to motorcycle tires.

    Moto tires are rounded, not flat like car tires. They’re designed to provide an optimal contact patch no matter the lean angle. Often, Moto tires won’t be perfectly rounded, but come to a bit of a point in the middle. This makes for a smaller contact patch going straight, for better fuel economy, and a bigger one while turning for more traction. Finally, moto tires are often made of multiple kinds of rubber: harder in the center for lower rolling resistance, and longer tread life; softer on the sides for more traction while turning.

    I’d bet that small bicycle tires share some of these characteristics, being rounded for sure, possibly others.
