Motorcycle tire set

A motorcycle tire set comprising a front wheel tire and a rear wheel tire, wherein

• each of the front wheel tire and the rear wheel tire has a plurality of inclined grooves provided on a tread portion thereof so as to be inclined in a tire circumferential direction,
• each of the plurality of inclined grooves includes a first portion extending in a crown region, a second portion extending in a shoulder region, and a third portion connecting the first portion and the second portion,
• the third portion has a smaller groove width than the first portion and the second portion,
• the first portion, the second portion, and the third portion are inclined in the same direction with respect to the tire circumferential direction,
• the tread portion of the rear wheel tire has a designated tire rotation direction,
• each of the plurality of inclined grooves of the rear wheel tire comes into contact with ground from the first portion toward the third portion based on the tire rotation direction,
• a shortest distance between each of the plurality of inclined grooves and a tire equator is less than 10% of a tread ground-contact width, without crossing the tire equator,
• in each of the plurality of inclined grooves of the rear wheel tire, the third portion extends in the crown region and the shoulder region,
• a midpoint of the third portion is provided in the shoulder region,
• the shoulder region is a region that comes into contact with the ground in a state in which a camber angle is given to the tire,
• the crown region is a region that comes into contact with a flat surface in a state in which the tire is brought into contact with the flat surface with a standardized load at the camber angle of 0 degrees,
• the third portion includes an inner end connected to the first portion,
• a shortest distance along a tread surface between the inner end and the tire equator is 30% to 55% of the tread ground-contact width,
• in each of the plurality of inclined grooves of the rear wheel tire, the third portion includes a first tapered portion having a groove width that decreases from the inner end toward the second portion, and an equal width portion extending with a constant groove width, and
• a virtual line obtained by extending a groove width center line of the equal width portion to the first portion is located on an outer side in a tire axial direction with respect to a groove width center line of the first portion.
