PURPOSE: A pneumatic tire with preventing separation is provided to prevent separation by reinforcing rigidity of a sidewall part and preventing both ends of a carcass turn up part from separating. CONSTITUTION: A pneumatic tire with preventing separation comprises a tread part(21), a side wall part(26), a bead part(27), and a carcass part(23) which comprises a first carcass(24) and a second carcass(25). The first carcass is formed in a belt layer(22) and the second carcass is formed in the first carcass layer. The both ends of the first carcass(28) are turned up through the bead part and inserted in between the belt layer and the carcass part. The both ends of the second carcass(29) are separated from the belt layer with a fixed distance. The width(AW) between both ends of the first carcass has a length of 76%-78% of the tread width(TW).
