Pneumatic tire

A pneumatic tire, comprising:

• a tread portion extending in a tire circumferential direction and having an annular shape;
• a pair of sidewall portions respectively disposed on both sides of the tread portion;
• a pair of bead portions each disposed on an inner side of a respective sidewall portion of the pair of sidewall portions in a tire radial direction;
• a carcass layer mounted between the pair of bead portions;
• at least one belt layer comprising an inner belt layer disposed adjacent to an outer circumferential side of the carcass layer in the tread portion;
• and
• a sealant layer made of an adhesive sealant provided on at least an inner surface of the tread portion;
• a width SW of the sealant layer, a width BW1 of the inner belt layer, and an actual ground contact width CW satisfying a relationship CW≤SW≤BW1;
• a thickness T1 of the tread portion and a thickness S1 of the sealant layer at the tire equator position satisfying a relationship 0.15<S1/T1<0.35;
• and
• a thickness T2 of the tread portion and a thickness S2 of the sealant layer at each end portion position of the sealant layer satisfying a relationship 0.20<S2/T2<0.40.
