Tread pattern transformable structure and system, tire and transformation method

The invention discloses a tread pattern transformable structure. The tread pattern transformable structure comprises a first tread blocky structure, a second tread blocky structure, a third tread blocky structure, a first pattern block, a second pattern block...an N pattern block, and N is an integer greater than or equal to 2. The invention also discloses a tread pattern transformable system,a tire and a transformation method, patterns with different styles can be automatically switched at any time according to road surface conditions, and a tire can deal with various road conditions; the patterns can be automatically switched to snow tire patterns in the snow field; on rainy days, the patterns can be automatically switched to patterns with good drainage performance; and on a dry land, the patterns can be automatically switched to patterns with good wear resistance. According to the road conditions, different patterns can be automatically switched anytime and anywhere to ensure the required performance of th
