These new tires with the dual compound are really cool. Sticky rubber on the edges, longer lasting rubber in the middle. I put a set of Road 2CT’s on my bike last summer and couldn’t be happier with them. Even did a track day on them and had a blast. Next thing they need is a tire that senses when you’re wearing out the middle and transfers rubber from the edges to the center. Now that would be cool and for some a HUGE money saver.
