Tire

The invention provides a tire (2), which can realize light weight while inhibiting the strength reduction of a tire body under the condition that the appearance quality is not damaged. A tire (2) is provided with a pair of beads (10), a carcass (12), an inner liner (20), and a separation layer (22) positioned between the carcass (12) and the inner liner (20). The carcass (12) is configured from a single carcass ply (42). The carcass ply (42) is composed of a plurality of carcass cords (44) and topping rubber (46). The total fineness of the carcass cords (44) is from 6000 dtex to 9000 dtex (inclusive). The isolation layer (22) is located between the first bead (10) and the second bead (10). The ratio (ta/td) of the thickness ta of the topping rubber (46) between the separation layer (22) and the carcass cord (44) to the thickness td of the separation layer (22) is from 0.2 to 0.6 (inclusive). 本发明提供一种轮胎(2)，其在不损害外观品质的情况下，能够抑制胎体的强度降低的同时实现轻量化。轮胎(2)具备一对胎圈(10)、胎体(12)、内衬层(20)和位于胎体(12)与内衬层(20)间的隔离层(22)。胎体(12)由一张胎体帘布层(
