Question

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

Answer 1

Fast cars need to grip the road well to maintain control at high speed. Wide tires let them contact a larger surface of road. Bicycles are just built as light as possible as you don’t reach the same speeds to have those problems
