<P>PROBLEM TO BE SOLVED: To improve riding comfort and steering stability, while securing capacity of an accommodation space S. <P>SOLUTION: A tire wheel assembly body 10 for an in-wheel motor includes a pneumatic tire 12 and a wheel 32. A carcass 24 is stretched over bead cores 20 at both ends via a tread part 14, and both ends of the carcass 24 are folded back at the bead core 20 so as to hold the bead core 20 and a bead filler 22 therebetween. The inner diameter of a bead section 18 located at the inner side of mounting on the vehicle is formed larger than that of a bead section 18 located at the outer side of mounting on the vehicle, to form a tire with a different diameter. When a tire cross sectional height at the inner side of mounting on the vehicle is defined as Hin, a tire cross sectional height at the outer side of mounting on the vehicle is defined as Hout, the height of the bead filler 22 at the inner side of mounting on the vehicle is defined as Fin, the height of the bead filler 22 at the outer side of mounting on the vehicle is Fout, and K is a coefficient, K.Hout/Hin=Fout/Fin, where 1.0≤K≤4.0 (expression 1) is satisfied. <P>COPYRIGHT: (C)2013,JPO&INPIT |
