Claim 1:
2. The tire mold according to claim 1, wherein, when a distance from the reference virtual point of intersection to the reference tangent point on a first side of the first projection side is denoted by Xw1m, a distance from the reference virtual point of intersection on the first side of the first projection to the reference virtual point of intersection on a second side of the second projection is denoted by Wcm, a cross-sectional area of the first projection is denoted by Sam, and a cross-sectional area of the second projection is denoted by Sbm, the distance Xw1m from the reference virtual point of intersection to the reference tangent point on the second side is set such that the following formula (1) is satisfied,

Sam/(Sam+Sbm)×100−10≤Xw1m/Wcm×100≤Sam/(Sam+Sbm)×100+10  (1)
