How do tubeless tires handle tire flex, particularly when cornering aggressively or navigating rough terrain, and are there any differences in how they respond compared to traditional clincher tires? Does the lack of a tube allow for more pronounced tire deformation, potentially leading to improved traction, or does the sealant and tire design mitigate this effect? Are there any specific tire designs or features that enhance the ability of a tubeless tire to handle flex, and do these features come with any trade-offs in terms of weight, durability, or rolling resistance?
