To reduce friction I believe? Because they are not needed necessarily unless the driver loses control and has to regain it. Therefore they only need to be small to balance the car
weight reduction bro!
Size of the contact patch really only affects wear. As long as the same amount of weight is on the tyres, and the surfaces are the same (same coefficient of friction), then theoretically speaking the maximum frictional force is the same. In reality it will be slightly lower for reasons I don’t quite understand. The wheels are also smaller so that there is less rotational inertia and less rolling resistance.
Simple, the center of gravity is lowered while still providing. they kind of don’t need traction because: 1. RWD and 2. You are going in a straingt line.
More friction(on non driven wheels) =less speed smaller tires =less friction
