Abstract
A non-pneumatic tire 1 comprises: a radially inner ring 3 coupled with an tire wheel H; a radially outer ring 2 comprising a radially outermost annular tread portion 5 having electrical conductivity, and a radially innermost second portion 6; and radial link portions 4 connecting between the radially outer and inner rings 2 and 3. The second portion 6, radial link portions 4 and radially inner ring 3 are each formed of a resin material containing carbon black to have electrical conductivity. The resin material comprises 0.5 to 20 parts by mass of carbon black having a BET specific surface area of from 300 to 1500 sq·m/g with respect to 100 parts by mass of its resin component. The tread portion 5 is electrically connected with the second portion 6.
Claims7
A non-pneumatic tire comprising:
- a radially outer ring comprising
- a radially outermost annular tread portion whose outer circumferential surface defines a tread surface contacting with the ground, and
- a radially innermost second portion disposed radially inside the tread portion;
- a radially inner ring disposed radially inside the radially outer ring and coupled with a tire wheel;
- and
- a plurality of radial link portions connecting between the radially outer ring and the radially inner ring,
- wherein
- the radially innermost second portion, the radial link portions and the radially inner ring are each formed of a resin material containing carbon black to have electrical conductivity, the resin material comprising 0.5 to 20 parts by mass of carbon black having a BET specific surface area of from 300 to 1500 sq·m/g with respect to 100 parts by mass of its resin component, and
- the radially outermost annular tread portion has electrical conductivity, and electrically connected with the radially innermost second portion.
