Mine also due to be replaced.
Mine is Road II CT??? something like that.
And it was good for 20,000 miles; YES 20 Thousands.
It has some more thread left at least for couple of more thousands.
But the tyre shape went il-regular forming that might not be big problem ??
And gripping power went down little bit.
I've never changed/added typr air pressure during the riding, amaizingly looks like it kept all the original air pressure???
My impressions are,
Best for the commuting or long distance touring on the highway.
At the curver; especially on the highway, bike does not need to be leaned much compared to the canyon tires.
But at the canyon, it does not give best confidence on the leaning >> just for me??
However, it is good enough to enjoy the twisties.. ha ha ha
