A non-pneumatic tire includes a rim part in which an insertion groove is formed and being connected with an axle; a tread part formed in a shape of surrounding an outer side of the tire in a circumferential direction thereof and being in contact with the ground; a spoke part formed between the rim part and the tread part and provided with upper arch bodies and lower arch bodies of an arch shape to absorb impacts transmitted from the ground to the tread part; a structural reinforcement part inserted into the inside of the tread part to perform load support and stress distribution of the spoke part; a conductive structure part formed between an outer surface of the rim part and an inner surface of the tread part, and having fiber plated using a metal salt.

A pneumatic tire includes a carcass layer, a belt layer, a tread rubber having a cap tread and an undertread, a pair of side wall rubbers, a pair of rim cushion rubbers, and a grounding tread that is exposed to a road contact surface of the tread rubber and that penetrates the cap tread and the undertread to contact the belt layer in an electrically conductive manner. The grounding tread includes a widened portion having a cross-sectional area that widens toward a contact surface with the belt layer at the contact portion with the belt layer. The widened portion of the grounding tread has a profile shape that bulges outward in a tire width direction.

The invention relates to a vehicle tire comprising a tread portion and a package of reinforcement layers arranged underneath the tread portion. The tread portion comprises a tread base layer arranged underneath the tread layer, and at least one rubber member that extends in the radial direction of the tire from the ground contacting surface to the reinforcement package. The tread layer rubber composition has an electrical resistivity at room temperature of more than 108 ohm-cm, the tread base layer rubber composition of between 106 ohm-cm and 108 ohm-cm, the member rubber composition of less than 106 ohm-cm; and the rubber composition of at least one layer of the reinforcement package has a electrical resistivity at room temperature of less than 106 ohm-cm. The vehicle tire combines a low rolling resistance with improved conductivity to avoid build-up of static electricity.
