Abstract: The article introduces a new energy electric vehicle specific tire with specifications and
modelsof 255/45R19. Structural design: Inflatable outer diameter 703mm, driving surface width 220mm,
inflatable section width 255mm; Pattern design: Longitudinal drainage grooves with variable width can
enhance the wet grip of tires; The inner and outer sides adopt different arrangements of silent variable pitch
design, effectively reducing driving vibration noise; The unique combination of soundproof grooves and
soundproof windows reduces the overall noise of the entire tire in all directions; Interlocking shoulder pattern
blocks can improve the smoothness of handling; Construction design: The tread adopts a special formula for
new energy electric vehicle tires, which has excellent wet grip, rolling resistance, and anti-static performance;
The tire sidewall is designed with a double composite design, and the belt consists of two layers of steel wire
#
cords, 1 and 2 , using 2+2×0.30HT steel wire. The steel wire ring is designed with a slanted hexagonal shape;
#
The molding process uses a Dutch VMI one-time molding machine, and the vulcanization process is nitrogen
vulcanization. The performance of the finished tires for new energy electric vehicles meets the research and
development standards.
Key words: construction design; specialized for new energy electric vehicles; tires; structural design; static
conductive pre mouth type
