<p>A pneumatic tire (1) comprises a pair of bead cores (10a) and a toroidal carcass layer (20) installed between the pair of bead cores (10a). The carcass layer (20) comprises a circumferential belt layer (70) installed on the tire radial outward of the carcass layer (20), an inner tilted belt layer (80) installed on the tire radial outward of the circumferential belt layer (70), and an outer tilted belt layer (90) installed on the tire radial outward of the inner tilted belt layer (80). An inner belt width (W2) is larger than an outer belt width (W3). The outer belt width (W3) is larger than a circumferential belt width (W1). Shoulder grooves are formed at the positions of 60-80% of a tread ground-contact width (TW) from a tire equator line (CL). The circumferential belt width (W1) is 70-90% of the tread ground-contact width (TW) from the tire equator line (CL).</p> |
