Can I apply for a patent for the tire platform?

D. 1 method can only be used for invention and creation. 2. Powder has no specific shape and structure. If it can be formed into a fixed shape by other devices, it can be applied to practical purposes, such as mercury in thermometers. 3. The granularity is not clear, and the material is not the object of actual protection. If the material is known, has a specific structure or is applied to a specific product, it can be applied to practical use. If it is not specified in the option, it is deemed not to belong to the above situation. In fact, in actual treatment, particulate matter can be applied to practice, but this is not what the questioner means. Option c is just a personal opinion, please give us your advice.
