Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to a new energy tire. Background Art

[0002] Generally, tire tread patterns include longitudinal grooves, transverse grooves and steel sheets.

[0003] With the increasing depletion of petroleum energy, the automotive industry is increasingly developing towards new energy. New energy vehicles impose more stringent usage conditions on the tires they use compared to gasoline / diesel engine vehicles, thus demanding more rigorous tread pattern designs:

[0004] 1. Lower noise requirements: The use of an electric motor instead of an engine in new energy vehicles reduces the overall vehicle noise, thus increasing the influence of tire noise on the vehicle.

[0005] 2. Higher grip performance: New energy vehicles reach maximum torque instantaneously when starting, so the tires used need higher grip.

[0006] 3. Higher wear resistance: New energy vehicles are generally heavier than fuel vehicles, so the tire load is increased, and thus higher wear resistance requirements are imposed on the tires. Content of the Utility Model
