Given the increasing trend of riders seamlessly transitioning between gravel and road disciplines, what are the key considerations when selecting a tire that can effectively balance the need for durability, traction, and rolling resistance in both environments? Is the conventional approach of choosing a tire with a moderate tread pattern and width truly the most effective, or are there emerging trends and technologies that suggest alternative approaches, such as the use of road-specific tires with enhanced puncture resistance or gravel-specific tires with optimized rolling resistance? How do factors such as tire casing, tread compound, and internal construction influence the overall performance and versatility of a tire in mixed-surface riding? Are there any notable examples of tires that have successfully bridged the gap between gravel and road riding, and what lessons can be learned from their design and development?
