Can you explain the cause of rolling friction?
Can you tell me why, while driving a bicycle, there is less rolling friction when its tyres are fully inflated?

You can get answer to your first question here.
When tires are inflated less area of the tire comes in contact with the ground, and thus there is less kinetic friction.

Friction is more if the Area of Contact of the tire is more.
When Air is completely filled in a Tire, the tire will be in lesser contact with the land as compared to when it has no or less air in it. This will lead to more friction by the tire, which will make it more difficult to drive the bicycle as compared to the earlier tire.
