The pattern is mainly to change the tire's grip, traction, friction, drainage performance, etc., and play a role in maintaining the tire, inspecting the service life of the tire, and improving the performance of the tire.
Different patterns represent different road conditions. The use of different patterns greatly affects the overall performance of tires. Ice and snow roads, cement roads and better gravel soil roads, indoor forklift real trailers, etc., can choose ordinary light For solid-surface tires or solid tires with ordinary patterns, the deeper the pattern, the greater the elastic deformation of the pattern block, and the corresponding rolling resistance will also increase. For example, a solid tire driving on a road with stagnant water, as the vehicle speed increases, the water between the tread and the road surface will form a water film between the two surfaces before it can be removed, and the tire will be slowly lifted, and under certain conditions, even completely off the road. , So that the vehicle completely loses maneuverability. This phenomenon is called the "water skiing phenomenon" of tires. Driving on gravel roads, steel mills, logging yards, mines and other environments have different requirements for tire patterns. Too shallow patterns not only affect its water storage and drainage functions.
In general, the pattern of solid rubber tires will gradually be worn out in use, becoming smaller and smaller. In order to ensure the effectiveness of the pattern, countries all over the world have formulated clear regulations on tire pattern wear limits. When the convex wear interval of the pattern block is about 1.6mm (1/16 inch) to the bottom of the pattern groove, the tire has reached the time when it is necessary to replace it.
