Note : There is no skidding. The tires roll smoothly.
Only static friction
Only kinetic friction

Well, obviously there's rolling friction, because the tires are rolling.
Static friction is also applied because since the tires roll smoothly (i.e. pure rolling), the contact point of the tire and road is always at rest. Static friction is applied to objects which are at rest but have a tendency to move.
