Question

why do the fastest bicycles have really thin tyres but the fastest cars have very wide tyres

In: Engineering

Answer 1

Fastest cars have narrow tires as well. See SSC Tuatara. You only need wire tires a) when cornering b) when accelerating c) while maintaining ridiculous speed due to air friction if you put the power down to the road using tires (unlike some rocket powered cars).
