Nevermind, Google was my friend. Good thing I will be changing them soon.What is dry rot? The tyres are only 18 months old.When I put knobby's on my bike there will be wide chicken strips. They are not made to be leaned over that far. Your right about the dry rot on that tire tho. If it were mine I would replace both tires.It appears to be a toss-up as to whether the tires will wear out or dry-rot first. You might try leaning the bike over to extend your mileage. The chicken strips look fine...
