Thank you for that bit of info.

My vision was Gumwalls, but after some research I came to realize that the only real gumwalls were as thin as tissue paper. The continental GP4000s tire has been great with flat protection and longevity has been just as good. My LBS just happened to 2 of these yellow sidewalls in the conti's left. It was a compromise on what I had planned. Still gives me a general idea on what I was visioning and the durability that I wouldn't fine in the Vitorria or veloflex.
