Motorcycle tire for running on rough terrain

A motorcycle tire having a block pattern suitable for running on rough terrain is disclosed. Each middle block overlaps with one of crown blocks at least partially in the tire circumferential direction. The top face of each crown block has an axially long rectangular shape. The top face of each middle block has a substantially pentagonal shape having five sides which are an axially inner side extending in the tire circumferential direction, a pair of transverse sides inclined so that the circumferential distance therebetween is gradually increased, and a pair of axially outer sides inclined so that the circumferential distance therebetween is gradually decreased. In a ground contacting patch of the tire in its normally inflated loaded condition and at the camber angle of zero, only an axially inner part of the top face of each middle block contacts with the ground.
