Answer 1

I feel like I’m having a stroke, half these answers are wrong and most of the other half seem like they didn’t even read the question correctly.

I interpret the question to be, why do offroad bicycles have fatter tires *when compared to bicycles meant for paved surfaces* while offroad motorcycles have skinner tires *when compared to motorcycles meant for paved surfaces*.

I don’t actually know the answer. But that’s what I think the question was asking.
