A tire 2 includes a tread 4 formed from a rubber composition containing: a rubber component including a styrene butadiene rubber; and a filler including silica. The tread 4 has a plurality of circumferential main grooves 10. The plurality of circumferential main grooves 10 define a pair of crown land portion 20 in the tread 4. Each crown land portion 20 has a crown narrow groove 24. Each crown narrow land portion 34 defined by the crown narrow groove 24 has a crown sipe 40. An amount CSB of the styrene butadiene rubber, an amount BS of the silica, a groove depth DGs of the crown sipe 40, and a groove depth DGg of the crown narrow groove 24 satisfy the following relational expression.(CSB+BS)/(DGg-DGs)≥5
