To provide a tire which uses thermoplastic elastomer and is excellent in stability.SOLUTION: A tire has a tread part and a side wall part which are formed of thermoplastic elastomer composition. A deviation A in a tire radial direction on an outermost surface of a tread crown part satisfies an expression (1) when a prescribed air pressure is filled after performing normal rim assembly: A≤3.0% ...(1). A total thickness T (mm) of the tread crown part and an outer diameter Dt (mm) of the tire satisfy an expression (2): T / Dt≤0.034 ...(2).<Prescribed air pressure> In a case that a virtual volume V of the tire is 15000 cm3 or more: 250 (kPa). In a case that the virtual volume V of the tire is less than 15000 cm3: 0.0152×V+22.553 (kPa). The virtual volume V (mm3) of the tire is calculated based on an outer diameter Dt (mm) of the tire, a sectional width Wt (mm), a cross section height H (mm) when the normal rim assembly is performed and an inner pressure is air pressure: V={(Dt / 2)2-(R / 2)2}×π×Wt; and R=Dt-2H.SELECTED DRAWING: None
