Abstract

A tire 2 includes a tread 4 and a reinforcing layer 14. The tread 4 includes a rubber composition containing a rubber component and a filler. The rubber component contains SBR and isoprene-based rubber. The filler contains carbon black and silica. The reinforcing layer 14 includes a reference full band BF. An amount CNR of the isoprene-based rubber, an amount BCB of the carbon black, and a ratio (Wj/Wt) of an axial width Wj of the reference full band BF to an axial width Wt of the tread 4 satisfy the following relational expression. CNR + BCB × Wj / Wt ≥ 27.0 <img class="EMIRef" id="4518fd5a-c5c6-4614-b11c-ce11b246765a-ia01" />
